The Server control provides support for the 3DS Server role as defined in the EMV® 3-D Secure (EMV 3DS) specification.

Syntax

Server

Remarks

This control is designed to be used in a web server, or in a process used by a web server to facilitate EMV® 3-D Secure (EMV 3DS) functionality. The control is used primarily for the browser-based flow, but also for some operations in the app-based flow as detailed in other parts of the documentation.

Connecting with SSL Client Authentication

Many directory servers require client authentication via a client certificate. The SSLCert* properties are used to load the SSL client certificate. In order to properly authenticate to the directory server the entire certificate chain must be presented to the directory server during the initial SSL handshake. The sections below describe options for making sure the CA chain is included.

Option 1: PFX With CA Certs

The first option is to specify a PFX file which includes both the client certificate, and CA certificates. In this case the control will read the CA certificates from the PFX file and include them in the request.

Option 2: SSLCACerts Configuration Setting

Another option is to specify the CA certificates separately from the client certificate. To do this the SSLCACerts configuration setting may be set to a CrLf separated list of CA certificates. For instance:

Option 3: CA Certs in Windows Store

When running on Windows the CA certificates will also be included in the request if they are present in the Personal store of the user under which the application is running.

Card Ranges

The application using the 3DS Server control should maintain a cache of card range information that can be queried when a transaction is initiated. The RequestCardRanges method will retrieve card range information to be cached.

RequestCardRanges requests card ranges and additional information from the directory server.

When a transaction is initiated, the first step that should be taken is to find information about the card range to which the card number belongs. This includes the protocol version(s) supported by the ACS and DS, and if one exists, any corresponding Method URL (used in the browser flow).

Results of this method should be cached in order to quickly look up information when processing transactions. It is recommended to call this method once every 24 hours at a minimum, and once per hour as a maximum to refresh the cache. The control will not cache the returned values; it is up to the user to cache these values in an appropriate location.

The first time this method is called, SerialNumber will be empty, indicating that all results should be returned. This is an offset the server will use to return only new updates to the card ranges (if any) since the last request. The SerialNumber will be populated after this method returns, and this value should be saved to be used in subsequent calls.

When a response is received, the card ranges will be made available via the component events and properties.

When MessageVersion is set to 2.3.1, the CardRangeData event will fire for each card range data object received, and the Ranges and ACSProtocolInfos properties will be populated to be accessed within the event handler. Optionally, the DS may return a list of URLs that the 3DS Server can use for communication with the DS. If present, these will be available via both the DSURL event and the DSURLs property.

When MessageVersion is set to 2.2.0 or 2.1.0, the CardRange event will fire for each card range that is returned, and the results will also be held in the CardRanges property.

The following properties are applicable when calling this method:

• DirectoryServerURL (required)
• SerialNumber
• ServerTransactionId
• ServerOperatorId
• EnableDownloadCardRangeDataFile (2.3.1 only)

The following properties are populated after calling this method:

• CardRanges
• DSStartProtocolVersion
• DSEndProtocolVersion
• SerialNumber
• DSTransactionId
• ResendRequestCardRanges

Note that when MessageVersion 2.3.1, the card range data is only available using the CardRangeData event.

When using MessageVersion 2.2.0 or 2.3.1, the returned ranges may include ACS Information Indicators. These are used to indicate additional functionality supported by the ACS for the card range(s). For 2.2.0, a ACSInformationIndicator field is exposed in both CardRanges collection and CardRange event. In version 2.3.1, this information is availalbe in the ACSProtocolInfos collection via the Indicator field. Possible values are:

• 01 - Authentication Available at ACS
• 02 - Attempts Supported by ACS or DS
• 03 - Decoupled Authentication Supported
• 04 - Whitelisting Supported
• 05 - Device Binding Supported (2.3.1 only)
• 06 - WebAuthn Authentication Supported (2.3.1 only)
• 07 - SPC Authentication Supported (2.3.1 only)
• 08 - Transaction Risk Analysis Exemption Supported (2.3.1 only)
• 09 - Trust List Exemption Supported (2.3.1 only)
• 10 - Low Value Exemption Supported (2.3.1 only)
• 11 - Secure Corporate Payments Exemption Supported (2.3.1 only)
• 80-99 - Reserved for DS Use

If an error is identified with the card range data received from the directory server when calling the RequestCardRanges method, the ResendRequestCardRanges configuration setting will be true, indicating that the request should be resent. When resending, if SerialNumber was specified for the initial request, it should be set to an empty string before calling RequestCardRanges again. Otherwise, the request can be sent without the serial number again, but the server may respond with an error due to multiple requests within an hour.

Note that retrieving card ranges can consume a lot of memory, especially when retrieving the initial set of ranges. The StoreCardRangeData and UseJsonDOM configuration settings can be set to help minimize the amount of memory used. A CardRangeTempPath setting can also be used to specify a temporary path to which the PRes packet will be temporarily written prior to parsing.

When using MessageVersion 2.3.1, if UseJsonDOM is false, the card ranges will need to be cached and processed after the RequestCardRanges method returns. The card ranges would then need to be processed in the order indicated by the CardRangeRecordsReadOrder configuration setting. A check will also need to be made for overlap of ranges. If issue(s) are found, the ReportCardRangeError configuration setting should be used to report the error to the directory server.

Method Invocation

The GetMethodData method prepares data to be transmitted to the ACS via the cardholder's browser.

When a transaction begins, the card range cache should be queried to find details about the card range to which the card number belongs. If a CardRangeMethodURL is defined for the card range, this method should be used to prepare data to be sent via the cardholder's browser to the CardRangeMethodURL.

If the CardRangeMethodURL is not set for the specified card range, set MethodCompletionIndicator to U before calling SendAuthRequest.

The following properties are applicable when calling this method:

• MethodNotificationURL (required)

This method returns a string which contains encoded data to be sent to the ACS. This includes ServerTransactionId and MethodNotificationURL. After calling this method, the returned string can be transmitted to the ACS via the cardholder's browser.

As per the EMVCo specification, create a hidden iframe in the browser and send a form with the field name threeDSMethodData containing the return value from this method and post the form to the CardRangeMethodURL.

The ACS will record information about the customer's environment and then POST back to the MethodNotificationURL. The page at this URL should expect a form variable with the name threeDSMethodData which will contain the original ServerTransactionId value in order to match the response with the request. The form variable value will be base64url encoded and may be passed directly to the CheckResponse method. The control will decode and parse the received value and populate ServerTransactionId with the value from the received data.

If the response from the ACS is not received within 10 seconds, set MethodCompletionIndicator to N before calling SendAuthRequest.

Sending the Authentication Request

SendAuthRequest begins the 3-D Secure transaction flow by sending an authentication request to the DirectoryServerURL.

After calling this method, check TransactionStatus to determine if the cardholder is authenticated (frictionless flow) or further cardholder interaction is required to complete the authentication (challenge flow).

Prior to calling SendAuthRequest, data must to be collected to facilitate fraud checks by the ACS. The following properties are applicable for both app-based and browser-based flows:

• AcquirerBIN (required)
• AcquirerMerchantId (required)
• CardholderName (required)
• CardNumber (required)
• DirectoryServerURL (required)
• MerchantCategoryCode (required)
• MerchantCountryCode (required)
• MerchantName (required)
• MessageVersion (required)
• PurchaseAmount (required)
• PurchaseDate (required)
• RequestorId (required)
• RequestorName (required)
• RequestorURL (required)
• ResultsURL (required)
• AccountType
• AuthenticationIndicator
• BillingAddress*
• CardholderEmail
• CardholderHomePhone
• CardholderMobilePhone
• CardholderWorkPhone
• DecoupledMaxTimeout
• DecoupledRequestIndicator
• DeviceChannel
• MessageCategory
• PurchaseCurrency
• PurchaseExponent
• ServerOperatorId
• ServerTransactionId
• ShippingAddress*
• ThreeRIIndicator

App-Based Flow

In the app-based flow, device specific information is prepared by the 3DS SDK on the customer's device. This is transmitted to the 3DS Server control via a secure channel, the specifics of which are outside the scope of the controls. Set ClientAuthRequest to this data prepared by the 3DS SDK.

Browser-Based Flow

Before calling this method, first check the cached card-range data to determine if a CardRangeMethodURL has been set by the ACS. Card range data may be retrieved by calling RequestCardRanges.

If no CardRangeMethodURL is present for the given card, set MethodCompletionIndicator to U.

If a CardRangeMethodURL has been specified by the ACS for the card number, the URL must be loaded in the cardholder's browser to allow the ACS to collect additional browser information for risk-based decision making. See the GetMethodData for further details.

Once the method URL invocation is complete, the authentication request may be sent. If the method URL invocation failed, set MethodCompletionIndicator to N before calling SendAuthRequest.

The following additional properties are applicable in browser-based flow:

• NotificationURL (required)
• BrowserAcceptHeader (required)
• BrowserLanguage (required)
• BrowserScreenHeight (required in 2.1.0, required in 2.2.0 and 2.3.1 if BrowserJavaScriptEnabled is true)
• BrowserScreenWidth (required in 2.1.0, required in 2.2.0 and 2.3.1 if BrowserJavaScriptEnabled is true)
• BrowserTimeZone (required in 2.1.0, required in 2.2.0 and 2.3.1 if BrowserJavaScriptEnabled is true)
• BrowserUserAgent (required)
• BrowserIPAddress (conditional)
• BrowserJavaEnabledVal (required in 2.1.0, required in 2.2.0 and 2.3.1 if BrowserJavaScriptEnabled is true)
• BrowserJavaScriptEnabledVal (not valid in 2.1.0, required in 2.2.0 and 2.3.1)
• BrowserScreenColorDepth (required in 2.1.0, required in 2.2.0 and 2.3.1 if BrowserJavaScriptEnabled is true)
• AcceptLanguage (2.3.1 only)
• AcquirerCountryCode (2.3.1 only)

Response Handling

After calling this method the TransactionStatus property holds the result. Possible values are:

If the transaction is authenticated (Y or A), no further steps are required. The flow is considered frictionless and the 3-D Secure processing is complete. If processing a payment, the AuthenticationValue and AuthenticationECI values can be included as proof of 3-D Secure authentication.

If the transaction requires a cardholder challenge (C, D or S), further steps are required.

If the transaction is not authenticated, TransactionStatusReason may contain details about the reason.

The following properties are applicable after calling this method:

• AuthenticationECI
• AuthenticationValue
• TransactionStatus
• TransactionStatusReason
• CardholderInformation
• ACSURL (if challenge required)
• ACSChallengeMandatedIndicator (if challenge required)
• AuthenticationType (if challenge required)
• DecoupledConfirmationIndicator

Response Handling - App-Based Flow

After calling this method, ClientAuthResponse is populated with data to be transmitted back to the 3DS SDK. If a challenge is required, the ClientAuthResponse data is used by the 3DS SDK to start when initiating the challenge process.

The 3DS Server is responsible for indicating to the 3DS SDK the results of the SendAuthRequest process, and whether or not a challenge is required. Exactly how this is done is outside the scope of the controls themselves. The response to the 3DS SDK over the secure channel should include information on what to do next.

Note: The TransactionStatus is also populated in the 3DS Server control and may be inspected prior to transmitting ClientAuthResponse back to the 3DS SDK.

Response Handling - Browser-Based Flow

If TransactionStatus is C, then additional steps are required to complete the authentication. The GetChallengeRequest method should be called next to obtain data to be sent to the ACSURL in an authentication window in the customer's browser. Once authentication is complete, the ACS will post the results to the ResultsURL value that was specified when calling SendAuthRequest.

See the GetChallengeRequest method for more details.

If TransactionStatus is D, then decoupled authentication has been accepted by the ACS. DecoupledConfirmationIndicator will have a value of Y as well. Authentication will happen outside of the 3-D Secure flow and, when complete, the ACS will post the results to the ResultsURL that was specified when calling SendAuthRequest.

The DecoupledTimeRemaining value, which is calculated based on the DecoupledMaxTimeout value sent in the initial authentication request, can be checked to see the amount of time remaining before decoupled authentication must be completed. If the ACS does not post the results before this value runs out, it can be assumed that decoupled authentication was not successful.

SPC-Based Authentication

SPC (Secure Payment Confirmation) provides a method to perform a challenge using preestablished FIDO credentials when using a Browser. The SPC authentication can be initiated by the 3DS Requestor via an extra AReq/ARes message pair or by the ACS via a standard Browser Challenge Flow.

For an SPC authentication to execute correctly, the following prerequisites apply:

1. The ACS has an enrolled FIDO authenticator on the device for this Cardholder.
2. The 3DS Requestor and/or the ACS have detected that the Cardholder Browser supports the related SPC APIs (allow="payment *; publickey-credentialsget *"). For the ACS, this information can be obtained via the Browser User Agent data element or via data obtained via the 3DS Method.

SPC-based authentication can be enabled with the following additions:

Prior to sending the initial authentication request packet (AReq) using the SendAuthRequest method, the ThreeDSRequestorSpcSupport configuration setting should be set to True to indicate that SPC is supported by the 3DS Requestor.

If SPC is accepted by the ACS, the resulting TransactionStatus should be S. The response will also contain a list of enrolled FIDO (WebAuthn) credentials associated with the cardholder, and SPC transaction data. This data is available in the following configuration settings:

• WebAuthnCredentialListCount
• WebAuthnCredentialListWebAuthnCredential
• WebAuthnCredentialListRelyingPartyId
• SPCTransactionAdditionalData
• SPCTransactionChallenge
• SPCTransactionChallengeInfoText
• SPCTransactionCurrency
• SPCTransactionDisplayName
• SPCTransactionIcon
• SPCTransactionIssuerImage
• SPCTransactionIssuerImageDark
• SPCTransactionIssuerImageMonochrome
• SPCTransactionPayeeName
• SPCTransactionPayeeOrigin
• SPCTransactionPSImage
• SPCTransactionPSImageDark
• SPCTransactionPSImageMonochrome
• SPCTransactionTimeout
• SPCTransactionValue

If a new instance of the Server component will be used after authentication to send the second AReq, the AuthenticationInformation value should be saved to be used later.

This information is relayed to the 3DS Requestor implementation, and the 3DS Requestor invokes the SPC authentication (SPC API) against the WebAuthn Credential list. The cardholder authenticates using the FIDO authenticator on their device, and the 3DS Requestor retrieves the Assertion Data from the SPC API call.

The 3DS Server is then configured to includes this FIDO Assertion Data is then included in a new authentication request by setting the ReqAuthData[Index] and a ReqAuthMethod[Index] of 09. If the AuthenticationInformation value was saved earlier, it can be set via the same configuration setting. If the 3DS Requestor encounters an error during SPC API invokation, this can be indicated using the SPCIncompletionIndicator.

The SendAuthRequest method should then be called again to transmit this data to the ACS (by way of the DS) in a second AReq.

When SendAuthRequest returns, the 3DS Server proceed the same as the regular browser-based flow when the ARes is returned.

When SPC authentication is to be performed, the authenticaton must be completed within 9 minutes. The component will automatically start an internal timer that can be checked using the CheckSPCTimeout configuration setting. This will return the number of seconds left for SPC authentication to complete. If the time has expired before receiving the Assertion Data from the 3DS Requestor, checking this configuration setting will cause the component to automatically send the second AReq message with an SPCIncompletionIndicator value of 03, indicating that SPC authentication timed out.

Note that SPC-based authentication is only available when a MessageVersion of 2.3.1 is used.

Challenge Interaction

If the TransactionStatus is C, a challenge is required.

The GetChallengeRequest method is used to build the Challenge Request (CReq) which will be sent in a form post to the ACSURL property via the cardholder browser.

An iframe should be created in the cardholder's browser, which will be used to send the challenge request and allow the cardholder and ACS to interact directly.

The size of the challenge window (iframe) may be any of the sizes listed in ChallengeWindowSize. Before calling this method set ChallengeWindowSize to the appropriate value to let the ACS know the size of the window on the cardholder's browser.

Calling this method will return a string which should be placed in a creq form variable.

The SessionData setting may also be set with any data that may be helpful to continue processing the transaction after the final challenge response is received at the NotificationURL. To prepare the session data for submission, query EncodedSessionData. The encoded string may then be placed in the threeDSSessionData form variable.

Note: The maximum length of the threeDSSessionData form variable, after being encoded, is 1024 bytes.

Example Form

Response Handling

Once the challenge has been completed by the cardholder, the directory server will post a Results Request (RReq) to the ResultsURL specified when calling SendAuthRequest. See CheckResponse and GetResultsResponse for more details.

The ACS will also post the Challenge Response to the NotificationURL specified when calling SendAuthRequest. This post contains data which may be parsed to verify the challenge results. See CheckResponse for more details.

Response Handling

After a challenge is complete, the Directory Server and ACS will POST data back to the web server for additional processing. CheckResponse parses a variety of messages that are sent to the Server as part of the authentication process.

The following messages can be parsed using this method:

• The threeDSMethodData form variables received at the MethodNotificationURL
• The Results Request (RReq) message received at the ResultsURL
• The cres form variables received at the NotificationURL
• The Operation Request Message (OReq) sent from a DS.

When calling the method, pass the message to be parsed as the Response parameter. The properties which are populated after calling this method vary depending on the type of message being parsed. See below for additional information.

Method Data from MethodNotificationURL

After calling GetMethodData, a request is made to the CardRangeMethodURL. After this, the ACS will make a POST to MethodNotificationURL to inform the requestor of completion. Retrieve the threeDSMethodData form variable value that was POSTed and pass it to this method. After calling this method, the following properties are populated:

• ServerTransactionId

The ServerTransactionId may be used to match the response with the request.

Results Request message from ResultsURL

When a challenge is completed for both app-based and browser-based flows, a POST is made to the ResultsURL with a Results Request message.

Prior to checking this RReq message, the ServerTransactionId can be extracted using the ExtractRReqServerTransactionId configuration setting. This value can then be used to look up details on the transaction that were saved prior to starting the challenge process, including the messageVersion which must be set via the MessageVersion property prior to passing the RReq message to the CheckResponse method.

Pass the body of the HTTP request received at ResultsURL to this method. This contains information about the results, and asks for a Results Response to be sent back containing the ResultsStatus.

After calling this method, the following properties are populated:

• AuthenticationECI
• TransactionStatus
• TransactionStatusReason
• ChallengeCancellationIndicator
• AuthenticationType
• AuthenticationValue

To respond to the POST, set ResultsStatus to the appropriate value and call GetResultsResponse to build a response message to be sent back to the directory server. Use the value from GetResultsResponse in the application as the body of the HTTP response. Set the Content-Type header to application/JSON; charset=utf-8

If TransactionStatus is D and TransactionStatusReason is 29 or 30, this indicates that decoupled authentication should now be performed. When building the Results Response, a ResultsStatus value of 04 should be used. Then, within 60 seconds, a new 3RI authentication must be started with the following field requirements:

• ThreeRIIndicator set to 19, indicating Decoupled Authentication Fallback
• DecoupledRequestIndicator set to Y
• AuthenticationInformation set with threeDSReqPriorRef set to the ACS Transaction ID and threeDSReqPriorAuthMethod set to 02 (Cardholder challenge occurred by ACS).

Final Challenge Response from NotificationURL

In a browser-based flow, the challenge takes place directly between the cardholder and the ACS in a separate iframe or window. The ACS will POST the final challenge response to the NotificationURL after the challenge is complete. Retrieve the cres form variable value from the POST data and pass it to CheckResponse. After calling this method the following properties are populated:

• ServerTransactionId
• TransactionStatus

In addition to the cres variable, a threeDSSessionData variable will be present if SessionData was set before calling GetChallengeRequest. The threeDSSessionData value POSTed to NotificationURL may be passed to EncodedSessionData. Query SessionData to get the decoded session data.

Operation Request Message (OReq)

OReq messages are used to communicate operational information from a DS to the 3DS Server. This message is not part of the 3-D Secure authentication flow.

When an OReq message is received, CheckResponse should be called to validate the message. There may be more than one OReq message sent in a sequence, and CheckResponse should be called for each. The current instance of the Server object can be cached for the duration of the OReq sequence until the final OReq is received. The Operation.SequenceNumber should also be set prior to calling CheckResponse. The component will verify the sequence number of the received OReq to ensure it's not out of sequence.

After calling this method, details are made available in Operation.

If any OReq data element fails validation, Operation.MessageStatus will be set to "02". If the OReq is valid, Operation.MessageStatus will be empty.

If the OReq is valid, determine if the final OReq has been received (Operation.SequenceNumber equals Operation.SequenceTotal). If these values match, the final OReq in the sequence has been received, and GetOperationResponse can be used to generate the ORes message.

For valid OReq messages that are not the final OReq in the sequence, the response should be HTTP Status 200 (OK) with an empty HTTP body.

Logging Notes

Logging in the component is handled through the Log event. This will fire anytime a message is built or a response is parsed, including error messages.

When the Log event is fired, the message in question is made available via the Message event parameter. Properties such as EphemeralKey and DeviceParams are also available when they are gathered by the Client. The other event arguments are LogType and LogLevel:

The LogType parameter indicates the type of the log entry. Possible values are:

• "Info"
• "RequestHeaders"
• "ResponseHeaders"
• "RequestBody"
• "ResponseBody"
• "ProxyRequest"
• "ProxyResponse"
• "FirewallRequest"
• "FirewallResponse"
• "AReq"
• "ARes"
• "CReq"
• "CRes"
• "RReq"
• "RRes"
• "PReq"
• "PRes"
• "Erro"
• "EphemeralKey"
• "DeviceParams"

The LogLevel configuration setting can be used to specify the detail of the logs raised through the Log event. The LogLevel parameter in the event indicates the log level to which the current message belongs.

It is recommended to output all messages raised in this event to a file for record keeping purposes, or for later debugging issues that may have come up.

The Server and Client components also have DataPacketIn and DataPacketOut events that fire anytime a data packet is received or sent, respectively. The entire data packet is then accessible in the DataPacket event parameter. For encrypted packets, this would contain the full encrypted data. This parameter may be inspected for advanced troubleshooting.

The following messages can be parsed using this method:

• The threeDSMethodData form variables received at the MethodNotificationURL
• The Results Request (RReq) message received at the ResultsURL
• The cres form variables received at the NotificationURL
• The Operation Request Message (OReq) sent from a DS.

When calling the method, pass the message to be parsed as the Response parameter. The properties which are populated after calling this method vary depending on the type of message being parsed. See below for additional information.

Method Data from MethodNotificationURL

After calling GetMethodData, a request is made to the CardRangeMethodURL. After this, the ACS will make a POST to MethodNotificationURL to inform the requestor of completion. Retrieve the threeDSMethodData form variable value that was POSTed and pass it to this method. After calling this method, the following properties are populated:

• ServerTransactionId

The ServerTransactionId may be used to match the response with the request.

Results Request message from ResultsURL

When a challenge is completed for both app-based and browser-based flows, a POST is made to the ResultsURL with a Results Request message.

Prior to checking this RReq message, the ServerTransactionId can be extracted using the ExtractRReqServerTransactionId configuration setting. This value can then be used to look up details on the transaction that were saved prior to starting the challenge process, including the messageVersion which must be set via the MessageVersion property prior to passing the RReq message to the CheckResponse method.

Pass the body of the HTTP request received at ResultsURL to this method. This contains information about the results, and asks for a Results Response to be sent back containing the ResultsStatus.

After calling this method, the following properties are populated:

• AuthenticationECI
• TransactionStatus
• TransactionStatusReason
• ChallengeCancellationIndicator
• AuthenticationType
• AuthenticationValue

To respond to the POST, set ResultsStatus to the appropriate value and call GetResultsResponse to build a response message to be sent back to the directory server. Use the value from GetResultsResponse in the application as the body of the HTTP response. Set the Content-Type header to application/JSON; charset=utf-8

If TransactionStatus is D and TransactionStatusReason is 29 or 30, this indicates that decoupled authentication should now be performed. When building the Results Response, a ResultsStatus value of 04 should be used. Then, within 60 seconds, a new 3RI authentication must be started with the following field requirements:

• ThreeRIIndicator set to 19, indicating Decoupled Authentication Fallback
• DecoupledRequestIndicator set to Y
• AuthenticationInformation set with threeDSReqPriorRef set to the ACS Transaction ID and threeDSReqPriorAuthMethod set to 02 (Cardholder challenge occurred by ACS).

Final Challenge Response from NotificationURL

In a browser-based flow, the challenge takes place directly between the cardholder and the ACS in a separate iframe or window. The ACS will POST the final challenge response to the NotificationURL after the challenge is complete. Retrieve the cres form variable value from the POST data and pass it to CheckResponse. After calling this method the following properties are populated:

• ServerTransactionId
• TransactionStatus

In addition to the cres variable, a threeDSSessionData variable will be present if SessionData was set before calling GetChallengeRequest. The threeDSSessionData value POSTed to NotificationURL may be passed to EncodedSessionData. Query SessionData to get the decoded session data.

Operation Request Message (OReq)

OReq messages are used to communicate operational information from a DS to the 3DS Server. This message is not part of the 3-D Secure authentication flow.

When an OReq message is received, CheckResponse should be called to validate the message. There may be more than one OReq message sent in a sequence, and CheckResponse should be called for each. The current instance of the Server object can be cached for the duration of the OReq sequence until the final OReq is received. The Operation.SequenceNumber should also be set prior to calling CheckResponse. The component will verify the sequence number of the received OReq to ensure it's not out of sequence.

After calling this method, details are made available in Operation.

If any OReq data element fails validation, Operation.MessageStatus will be set to "02". If the OReq is valid, Operation.MessageStatus will be empty.

If the OReq is valid, determine if the final OReq has been received (Operation.SequenceNumber equals Operation.SequenceTotal). If these values match, the final OReq in the sequence has been received, and GetOperationResponse can be used to generate the ORes message.

For valid OReq messages that are not the final OReq in the sequence, the response should be HTTP Status 200 (OK) with an empty HTTP body.

Config Method (Server Control)

Sets or retrieves a configuration setting.

Syntax

servercontrol.Config ConfigurationString

Remarks

Config is a generic method available in every control. It is used to set and retrieve configuration settings for the control.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the control, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

GetChallengeRequest Method (Server Control)

Builds the Challenge Request (CReq) for browser-based flow.

Syntax

servercontrol.GetChallengeRequest 

Remarks

The GetChallengeRequest method is used to build the Challenge Request (CReq) which will be sent in a form post to the ACSURL property via the cardholder browser.

An iframe should be created in the cardholder's browser, which will be used to send the challenge request and allow the cardholder and ACS to interact directly.

The size of the challenge window (iframe) may be any of the sizes listed in ChallengeWindowSize. Before calling this method set ChallengeWindowSize to the appropriate value to let the ACS know the size of the window on the cardholder's browser.

Calling this method will return a string which should be placed in a creq form variable.

The SessionData setting may also be set with any data that may be helpful to continue processing the transaction after the final challenge response is received at the NotificationURL. To prepare the session data for submission, query EncodedSessionData. The encoded string may then be placed in the threeDSSessionData form variable.

Note: The maximum length of the threeDSSessionData form variable, after being encoded, is 1024 bytes.

Example Form

Response Handling

Once the challenge has been completed by the cardholder, the directory server will post a Results Request (RReq) to the ResultsURL specified when calling SendAuthRequest. See CheckResponse and GetResultsResponse for more details.

The ACS will also post the Challenge Response to the NotificationURL specified when calling SendAuthRequest. This post contains data which may be parsed to verify the challenge results. See CheckResponse for more details.

GetMethodData Method (Server Control)

Prepares method data to be sent to the ACS before the authentication request is sent.

Syntax

servercontrol.GetMethodData 

Remarks

The GetMethodData method prepares data to be transmitted to the ACS via the cardholder's browser.

When a transaction begins, the card range cache should be queried to find details about the card range to which the card number belongs. If a CardRangeMethodURL is defined for the card range, this method should be used to prepare data to be sent via the cardholder's browser to the CardRangeMethodURL.

If the CardRangeMethodURL is not set for the specified card range, set MethodCompletionIndicator to U before calling SendAuthRequest.

The following properties are applicable when calling this method:

• MethodNotificationURL (required)

This method returns a string which contains encoded data to be sent to the ACS. This includes ServerTransactionId and MethodNotificationURL. After calling this method, the returned string can be transmitted to the ACS via the cardholder's browser.

As per the EMVCo specification, create a hidden iframe in the browser and send a form with the field name threeDSMethodData containing the return value from this method and post the form to the CardRangeMethodURL.

The ACS will record information about the customer's environment and then POST back to the MethodNotificationURL. The page at this URL should expect a form variable with the name threeDSMethodData which will contain the original ServerTransactionId value in order to match the response with the request. The form variable value will be base64url encoded and may be passed directly to the CheckResponse method. The control will decode and parse the received value and populate ServerTransactionId with the value from the received data.

If the response from the ACS is not received within 10 seconds, set MethodCompletionIndicator to N before calling SendAuthRequest.

GetOperationResponse Method (Server Control)

Builds and returns the Operation Response Message (ORes) to be sent back to the Directory Server.

Syntax

servercontrol.GetOperationResponse 

Remarks

This method builds the Operation Response Message (ORes) to be sent back to the Directory Server in an HTTP reply to the final Operation Request (OReq) message. It returns a JSON object containing the fields required for the ORes.

When an OReq message is received, CheckResponse should be called to validate the message. There may be more than one OReq message sent in a sequence, and CheckResponse should be called for each. While several OReq messages may be received in a sequence (totalling Operation.SequenceTotal), the ORes message is only expected to be generated using GetOperationResponse after the final OReq. For valid intermediate OReq messages the response should be HTTP Status 200 (OK) with an empty HTTP body.

After passing the final received OReq message to the CheckResponse method, all the properties required to be set before building the ORes will have been populated except for Operation.MessageStatus, which indicates whether or not the message was successfully received for further processing, or provides more detail to the DS on why the requested action could not be completed.

Possible values include:

If any OReq data element fails validation from CheckResponse, Operation.MessageStatus will be set to "02". The ErrorPacket can be queried and should be returned to the DS.

For valid OReq messages, Operation.MessageStatus will be empty. Next, determine if the final OReq has been received (Operation.SequenceNumber equals Operation.SequenceTotal). If these values match, the final OReq in the sequence has been received, and GetOperationResponse can be used to generate the ORes message.

Once Operation.MessageStatus has been set, GetOperationResponse can be called and will return a string containing the reply to be sent in the response. In the HTTP server, use the string returned from this method as the body of the reply and set the Content-Type header to application/JSON; charset=utf-8

GetResultsResponse Method (Server Control)

Builds and returns the Results Response Message (RRes) to be sent back to the directory server.

Syntax

servercontrol.GetResultsResponse 

Remarks

This method builds the Results Response Message (RRes) to be sent back to the directory server in the HTTP reply to the Results Request (RReq). It returns a JSON object containing the fields required for the RRes.

After passing the received RReq message to the CheckResponse method, all the properties required to be set before building the RRes will have been populated except for ResultsStatus, which indicates whether or not the message was successfully received for further processing, or provides more detail to the ACS on why the challenge could not be completed.

Possible values include:

The Server can use the value of the RequestorChallengeInd to determine whether or not a value of 02 is appropriate. It must use the necessary error handling logic when processing ARes messages to determine whether or not a value of 03 is appropriate.

Once ResultsStatus has been set, GetResultsResponse can be called and will return a string containing the reply to be sent in the response. In the HTTP server, use the string returned from this method as the body of the reply and set the Content-Type header to application/JSON; charset=utf-8

Interrupt Method (Server Control)

Interrupts the current action.

Syntax

servercontrol.Interrupt 

Remarks

This method interrupts any processing that the control is currently executing.

RequestCardRanges Method (Server Control)

Requests card ranges from the directory server.

Syntax

servercontrol.RequestCardRanges 

Remarks

RequestCardRanges requests card ranges and additional information from the directory server.

When a transaction is initiated, the first step that should be taken is to find information about the card range to which the card number belongs. This includes the protocol version(s) supported by the ACS and DS, and if one exists, any corresponding Method URL (used in the browser flow).

Results of this method should be cached in order to quickly look up information when processing transactions. It is recommended to call this method once every 24 hours at a minimum, and once per hour as a maximum to refresh the cache. The control will not cache the returned values; it is up to the user to cache these values in an appropriate location.

The first time this method is called, SerialNumber will be empty, indicating that all results should be returned. This is an offset the server will use to return only new updates to the card ranges (if any) since the last request. The SerialNumber will be populated after this method returns, and this value should be saved to be used in subsequent calls.

When a response is received, the card ranges will be made available via the component events and properties.

When MessageVersion is set to 2.3.1, the CardRangeData event will fire for each card range data object received, and the Ranges and ACSProtocolInfos properties will be populated to be accessed within the event handler. Optionally, the DS may return a list of URLs that the 3DS Server can use for communication with the DS. If present, these will be available via both the DSURL event and the DSURLs property.

When MessageVersion is set to 2.2.0 or 2.1.0, the CardRange event will fire for each card range that is returned, and the results will also be held in the CardRanges property.

The following properties are applicable when calling this method:

• DirectoryServerURL (required)
• SerialNumber
• ServerTransactionId
• ServerOperatorId
• EnableDownloadCardRangeDataFile (2.3.1 only)

The following properties are populated after calling this method:

• CardRanges
• DSStartProtocolVersion
• DSEndProtocolVersion
• SerialNumber
• DSTransactionId
• ResendRequestCardRanges

Note that when MessageVersion 2.3.1, the card range data is only available using the CardRangeData event.

When using MessageVersion 2.2.0 or 2.3.1, the returned ranges may include ACS Information Indicators. These are used to indicate additional functionality supported by the ACS for the card range(s). For 2.2.0, a ACSInformationIndicator field is exposed in both CardRanges collection and CardRange event. In version 2.3.1, this information is availalbe in the ACSProtocolInfos collection via the Indicator field. Possible values are:

• 01 - Authentication Available at ACS
• 02 - Attempts Supported by ACS or DS
• 03 - Decoupled Authentication Supported
• 04 - Whitelisting Supported
• 05 - Device Binding Supported (2.3.1 only)
• 06 - WebAuthn Authentication Supported (2.3.1 only)
• 07 - SPC Authentication Supported (2.3.1 only)
• 08 - Transaction Risk Analysis Exemption Supported (2.3.1 only)
• 09 - Trust List Exemption Supported (2.3.1 only)
• 10 - Low Value Exemption Supported (2.3.1 only)
• 11 - Secure Corporate Payments Exemption Supported (2.3.1 only)
• 80-99 - Reserved for DS Use

If an error is identified with the card range data received from the directory server when calling the RequestCardRanges method, the ResendRequestCardRanges configuration setting will be true, indicating that the request should be resent. When resending, if SerialNumber was specified for the initial request, it should be set to an empty string before calling RequestCardRanges again. Otherwise, the request can be sent without the serial number again, but the server may respond with an error due to multiple requests within an hour.

Note that retrieving card ranges can consume a lot of memory, especially when retrieving the initial set of ranges. The StoreCardRangeData and UseJsonDOM configuration settings can be set to help minimize the amount of memory used. A CardRangeTempPath setting can also be used to specify a temporary path to which the PRes packet will be temporarily written prior to parsing.

When using MessageVersion 2.3.1, if UseJsonDOM is false, the card ranges will need to be cached and processed after the RequestCardRanges method returns. The card ranges would then need to be processed in the order indicated by the CardRangeRecordsReadOrder configuration setting. A check will also need to be made for overlap of ranges. If issue(s) are found, the ReportCardRangeError configuration setting should be used to report the error to the directory server.

Reset Method (Server Control)

Clears all properties to their default values.

Syntax

servercontrol.Reset 

Remarks

This method clears all properties to their default values.

ResetTransactionInfo Method (Server Control)

Resets transaction specific information.

Syntax

servercontrol.ResetTransactionInfo 

Remarks

This method must be called between transactions when using the same control instance.

Each transaction that is attempted uses transaction specific values that should not be re-used in subsequent transactions. Call this method to make sure that any transaction specific information is cleared between transactions.

This method resets only the transaction specific information without resetting any other values which have been configured. This allows re-use of the same component instance.

SendAuthRequest Method (Server Control)

Sends the authentication request to the directory server.

Syntax

servercontrol.SendAuthRequest 

Remarks

SendAuthRequest begins the 3-D Secure transaction flow by sending an authentication request to the DirectoryServerURL.

After calling this method, check TransactionStatus to determine if the cardholder is authenticated (frictionless flow) or further cardholder interaction is required to complete the authentication (challenge flow).

Prior to calling SendAuthRequest, data must to be collected to facilitate fraud checks by the ACS. The following properties are applicable for both app-based and browser-based flows:

• AcquirerBIN (required)
• AcquirerMerchantId (required)
• CardholderName (required)
• CardNumber (required)
• DirectoryServerURL (required)
• MerchantCategoryCode (required)
• MerchantCountryCode (required)
• MerchantName (required)
• MessageVersion (required)
• PurchaseAmount (required)
• PurchaseDate (required)
• RequestorId (required)
• RequestorName (required)
• RequestorURL (required)
• ResultsURL (required)
• AccountType
• AuthenticationIndicator
• BillingAddress*
• CardholderEmail
• CardholderHomePhone
• CardholderMobilePhone
• CardholderWorkPhone
• DecoupledMaxTimeout
• DecoupledRequestIndicator
• DeviceChannel
• MessageCategory
• PurchaseCurrency
• PurchaseExponent
• ServerOperatorId
• ServerTransactionId
• ShippingAddress*
• ThreeRIIndicator

App-Based Flow

In the app-based flow, device specific information is prepared by the 3DS SDK on the customer's device. This is transmitted to the 3DS Server control via a secure channel, the specifics of which are outside the scope of the controls. Set ClientAuthRequest to this data prepared by the 3DS SDK.

Browser-Based Flow

Before calling this method, first check the cached card-range data to determine if a CardRangeMethodURL has been set by the ACS. Card range data may be retrieved by calling RequestCardRanges.

If no CardRangeMethodURL is present for the given card, set MethodCompletionIndicator to U.

If a CardRangeMethodURL has been specified by the ACS for the card number, the URL must be loaded in the cardholder's browser to allow the ACS to collect additional browser information for risk-based decision making. See the GetMethodData for further details.

Once the method URL invocation is complete, the authentication request may be sent. If the method URL invocation failed, set MethodCompletionIndicator to N before calling SendAuthRequest.

The following additional properties are applicable in browser-based flow:

• NotificationURL (required)
• BrowserAcceptHeader (required)
• BrowserLanguage (required)
• BrowserScreenHeight (required in 2.1.0, required in 2.2.0 and 2.3.1 if BrowserJavaScriptEnabled is true)
• BrowserScreenWidth (required in 2.1.0, required in 2.2.0 and 2.3.1 if BrowserJavaScriptEnabled is true)
• BrowserTimeZone (required in 2.1.0, required in 2.2.0 and 2.3.1 if BrowserJavaScriptEnabled is true)
• BrowserUserAgent (required)
• BrowserIPAddress (conditional)
• BrowserJavaEnabledVal (required in 2.1.0, required in 2.2.0 and 2.3.1 if BrowserJavaScriptEnabled is true)
• BrowserJavaScriptEnabledVal (not valid in 2.1.0, required in 2.2.0 and 2.3.1)
• BrowserScreenColorDepth (required in 2.1.0, required in 2.2.0 and 2.3.1 if BrowserJavaScriptEnabled is true)
• AcceptLanguage (2.3.1 only)
• AcquirerCountryCode (2.3.1 only)

Response Handling

After calling this method the TransactionStatus property holds the result. Possible values are:

If the transaction is authenticated (Y or A), no further steps are required. The flow is considered frictionless and the 3-D Secure processing is complete. If processing a payment, the AuthenticationValue and AuthenticationECI values can be included as proof of 3-D Secure authentication.

If the transaction requires a cardholder challenge (C, D or S), further steps are required.

If the transaction is not authenticated, TransactionStatusReason may contain details about the reason.

The following properties are applicable after calling this method:

• AuthenticationECI
• AuthenticationValue
• TransactionStatus
• TransactionStatusReason
• CardholderInformation
• ACSURL (if challenge required)
• ACSChallengeMandatedIndicator (if challenge required)
• AuthenticationType (if challenge required)
• DecoupledConfirmationIndicator

Response Handling - App-Based Flow

After calling this method, ClientAuthResponse is populated with data to be transmitted back to the 3DS SDK. If a challenge is required, the ClientAuthResponse data is used by the 3DS SDK to start when initiating the challenge process.

The 3DS Server is responsible for indicating to the 3DS SDK the results of the SendAuthRequest process, and whether or not a challenge is required. Exactly how this is done is outside the scope of the controls themselves. The response to the 3DS SDK over the secure channel should include information on what to do next.

Note: The TransactionStatus is also populated in the 3DS Server control and may be inspected prior to transmitting ClientAuthResponse back to the 3DS SDK.

Response Handling - Browser-Based Flow

If TransactionStatus is C, then additional steps are required to complete the authentication. The GetChallengeRequest method should be called next to obtain data to be sent to the ACSURL in an authentication window in the customer's browser. Once authentication is complete, the ACS will post the results to the ResultsURL value that was specified when calling SendAuthRequest.

See the GetChallengeRequest method for more details.

If TransactionStatus is D, then decoupled authentication has been accepted by the ACS. DecoupledConfirmationIndicator will have a value of Y as well. Authentication will happen outside of the 3-D Secure flow and, when complete, the ACS will post the results to the ResultsURL that was specified when calling SendAuthRequest.

The DecoupledTimeRemaining value, which is calculated based on the DecoupledMaxTimeout value sent in the initial authentication request, can be checked to see the amount of time remaining before decoupled authentication must be completed. If the ACS does not post the results before this value runs out, it can be assumed that decoupled authentication was not successful.

SPC-Based Authentication

SPC (Secure Payment Confirmation) provides a method to perform a challenge using preestablished FIDO credentials when using a Browser. The SPC authentication can be initiated by the 3DS Requestor via an extra AReq/ARes message pair or by the ACS via a standard Browser Challenge Flow.

For an SPC authentication to execute correctly, the following prerequisites apply:

1. The ACS has an enrolled FIDO authenticator on the device for this Cardholder.
2. The 3DS Requestor and/or the ACS have detected that the Cardholder Browser supports the related SPC APIs (allow="payment *; publickey-credentialsget *"). For the ACS, this information can be obtained via the Browser User Agent data element or via data obtained via the 3DS Method.

SPC-based authentication can be enabled with the following additions:

Prior to sending the initial authentication request packet (AReq) using the SendAuthRequest method, the ThreeDSRequestorSpcSupport configuration setting should be set to True to indicate that SPC is supported by the 3DS Requestor.

If SPC is accepted by the ACS, the resulting TransactionStatus should be S. The response will also contain a list of enrolled FIDO (WebAuthn) credentials associated with the cardholder, and SPC transaction data. This data is available in the following configuration settings:

• WebAuthnCredentialListCount
• WebAuthnCredentialListWebAuthnCredential
• WebAuthnCredentialListRelyingPartyId
• SPCTransactionAdditionalData
• SPCTransactionChallenge
• SPCTransactionChallengeInfoText
• SPCTransactionCurrency
• SPCTransactionDisplayName
• SPCTransactionIcon
• SPCTransactionIssuerImage
• SPCTransactionIssuerImageDark
• SPCTransactionIssuerImageMonochrome
• SPCTransactionPayeeName
• SPCTransactionPayeeOrigin
• SPCTransactionPSImage
• SPCTransactionPSImageDark
• SPCTransactionPSImageMonochrome
• SPCTransactionTimeout
• SPCTransactionValue

If a new instance of the Server component will be used after authentication to send the second AReq, the AuthenticationInformation value should be saved to be used later.

This information is relayed to the 3DS Requestor implementation, and the 3DS Requestor invokes the SPC authentication (SPC API) against the WebAuthn Credential list. The cardholder authenticates using the FIDO authenticator on their device, and the 3DS Requestor retrieves the Assertion Data from the SPC API call.

The 3DS Server is then configured to includes this FIDO Assertion Data is then included in a new authentication request by setting the ReqAuthData[Index] and a ReqAuthMethod[Index] of 09. If the AuthenticationInformation value was saved earlier, it can be set via the same configuration setting. If the 3DS Requestor encounters an error during SPC API invokation, this can be indicated using the SPCIncompletionIndicator.

The SendAuthRequest method should then be called again to transmit this data to the ACS (by way of the DS) in a second AReq.

When SendAuthRequest returns, the 3DS Server proceed the same as the regular browser-based flow when the ARes is returned.

When SPC authentication is to be performed, the authenticaton must be completed within 9 minutes. The component will automatically start an internal timer that can be checked using the CheckSPCTimeout configuration setting. This will return the number of seconds left for SPC authentication to complete. If the time has expired before receiving the Assertion Data from the 3DS Requestor, checking this configuration setting will cause the component to automatically send the second AReq message with an SPCIncompletionIndicator value of 03, indicating that SPC authentication timed out.

Note that SPC-based authentication is only available when a MessageVersion of 2.3.1 is used.

CardRange Event (Server Control)

Fired when the response to a Preparation Request Message (PReq) is received.

Syntax

Sub servercontrol_CardRange(RangeStart As String, RangeEnd As String, RangeAction As String, ACSStartProtocolVersion As String, ACSEndProtocolVersion As String, DSStartProtocolVersion As String, DSEndProtocolVersion As String, ThreeDSMethodURL As String, ACSInformationIndicator As String, Valid As Boolean)

Remarks

The CardRange event fires for each range of card numbers to be added or removed from the cache. The RangeAction parameter indicates whether the range specified by the RangeStart and RangeEnd arguments is to be added or deleted from the current cache.

Note that the card ranges must be processed in the order returned.

These card ranges are also returned outside this event in the CardRangeStart, CardRangeEnd, CardRangeAction, CardRangeACSStartProtocolVersion, CardRangeACSEndProtocolVersion, and CardRangeMethodURL properties.

CardRangeData Event (Server Control)

Fired when the response to a Preparation Request Message (PReq) is received. This event is used for card range data returned when version 2.3.1 of the protocol is used.

Syntax

Sub servercontrol_CardRangeData(RangeAction As String, IssuerCountryCode As String, DSProtocolVersions As Integer, Status As Integer)

Remarks

When card ranges are requested using using MessageVersion 2.3.1, the CardRangeData event will fire for each card range data object received in the Preparation Response Message (PRes) returned from the directory server.

This data indicates the most recent protocol versions supported by the ACS and, optionally, the DS that hosts that range. If configured, the ACS URL for the 3DS Method will be included as well, along with the 3DS features supported by the ACS, such as Trust List or Decoupled Authentication.

The RangeAction parameter indicates whether the ranges defined in the Ranges property are to be added, deleted, or modified in the current cache.

Within the event, a few properties will also be populated, both with details for the current ranges in question. The Ranges collection will hold the card ranges for which the rest of the data applies. The ACSProtocolInfos collection will hold protocol versions and other associated information supported by the ACS for the card ranges.

DataPacketIn Event (Server Control)

Fired when receiving a data packet from the server.

Syntax

Sub servercontrol_DataPacketIn(DataPacket As String)

Remarks

This event fires when a packet is received. The entire data packet (including all framing and error detection characters) is contained in the DataPacket parameter. This parameter may be inspected for advanced troubleshooting, or to extract additional response properties beyond the scope of this component.

DataPacketOut Event (Server Control)

Fired when sending a data packet to the server.

Syntax

Sub servercontrol_DataPacketOut(DataPacket As String)

Remarks

This event fires right before each data packet is sent. The entire data packet (including all framing and error detection characters) is contained in the DataPacket parameter. This parameter may be inspected for advanced troubleshooting, or may be modified to support additional features beyond the scope of this component.

DSURL Event (Server Control)

Fired for each DS URL present in the Preparation Response Message (PRes).

Syntax

Sub servercontrol_DSURL(ThreeDSServerToDsUrl As String, DSCountryCode As String)

Remarks

The DSURL event fires for each DS URL returned from the directory server when requesting card ranges via the RequestCardRanges method.

Each DSURL object contains a ThreeDSServerToDsUrl and, optionally, a CountryCode. For a given card range, if the Issuer Country Code matches the DS CountryCode, the 3DS Server uses this ThreeDSServerToDsUrl to communicate with the DS. If there is no match, the 3DS Server uses the default 3DS Server to DS URL.

Error Event (Server Control)

Information about errors during data delivery.

Syntax

Sub servercontrol_Error(ErrorCode As Integer, Description As String)

Remarks

The Error event is fired in case of exceptional conditions during message processing.

ErrorCode contains an error code and Description contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

Log Event (Server Control)

Fires once for each log message.

Syntax

Sub servercontrol_Log(LogLevel As Integer, Message As String, LogType As String)

Remarks

Logging in the component is handled through the Log event. This will fire anytime a message is built or a response is parsed, including error messages.

When the Log event is fired, the message in question is made available via the Message event parameter. Properties such as EphemeralKey and DeviceParams are also available when they are gathered by the Client. The other event arguments are LogType and LogLevel:

The LogType parameter indicates the type of the log entry. Possible values are:

• "Info"
• "RequestHeaders"
• "ResponseHeaders"
• "RequestBody"
• "ResponseBody"
• "ProxyRequest"
• "ProxyResponse"
• "FirewallRequest"
• "FirewallResponse"
• "AReq"
• "ARes"
• "CReq"
• "CRes"
• "RReq"
• "RRes"
• "PReq"
• "PRes"
• "Erro"
• "EphemeralKey"
• "DeviceParams"

The LogLevel configuration setting can be used to specify the detail of the logs raised through the Log event. The LogLevel parameter in the event indicates the log level to which the current message belongs.

It is recommended to output all messages raised in this event to a file for record keeping purposes, or for later debugging issues that may have come up.

The Server and Client components also have DataPacketIn and DataPacketOut events that fire anytime a data packet is received or sent, respectively. The entire data packet is then accessible in the DataPacket event parameter. For encrypted packets, this would contain the full encrypted data. This parameter may be inspected for advanced troubleshooting.

MessageExtension Event (Server Control)

Fired when a Message Extension is present in a message being parsed.

Syntax

Sub servercontrol_MessageExtension(Name As String, Id As String, Data As String, Critical As Boolean, Recognized As Boolean)

Remarks

Enables the parsing of Message Extension data by firing when extensions have been included in a ARes, CRes, RReq or PRes message that is being parsed. Message Extensions carry additional data not defined in the 3DS Protocol. This event fires once for each such extension. Event arguments correspond to the four elements comprising the extension, as well as an indication of whether or not the extension is recognized:

If a 3-D Secure application receives a message containing a critical extension that it does not recognize, it must treat it as invalid and return Error Code = 202. This event will fire before the exception is thrown.

SSLServerAuthentication Event (Server Control)

Fired after the server presents its certificate to the client.

Syntax

Sub servercontrol_SSLServerAuthentication(CertEncoded As String, CertSubject As String, CertIssuer As String, Status As String, Accept As Boolean)

Remarks

During this event, the client can decide whether or not to continue with the connection process. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether or not to continue.

When Accept is False, Status shows why the verification failed (otherwise, Status contains the string OK). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.

SSLStatus Event (Server Control)

Fired when secure connection progress messages are available.

Syntax

Sub servercontrol_SSLStatus(Message As String)

Remarks

The event is fired for informational and logging purposes only. This event tracks the progress of the connection.

Config Settings (Server Control)

The control accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the control, access to these internal properties is provided through the Config method.

Server Config Settings

SSL Config Settings

Trappable Errors (Server Control)

Server Errors

HTTP Errors

The control may also return one of the following error codes, which are inherited from other controls.

TCPClient Errors

SSL Errors

TCP/IP Errors
