The 3DS Server class provides support 3-D Secure 2.0 functionality designed with a web server in mind.




This class is designed to be used in a web server, or in a process used by a web server to facilitate 3-D Secure 2.0 functionality. The class 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 class 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:

PHP Example

$ca_int = <<<EOT

$ca_root = <<<EOT

$server->doConfig('SSLCACerts=' . $ca_int . '\n' . $ca_root);

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 class 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 include the protocol version number 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 for subsequent 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 first time this method is called, SerialNumber will be empty, indicating that all results should be returned. The CardRange event will fire for each result that is returned. The results will also be held in the CardRanges property.

The class will not cache the returned values; it is up to the user to cache these values in an appropriate location. The SerialNumber will be populated after this method returns. The SerialNumber should also be saved to be used in the next call to this method.

When making subsequent calls to this method, set SerialNumber to the value received from the last response. This is an offset the server will use to return only new updates (if any) to the card ranges since the last request.

The following properties are applicable when calling this method:

The following properties are populated after calling this method:

When using ProtocolVersion 2.2.0, CardRanges may also include ACSInformationIndicator data. This provides additional information on the functionality that is supported for the card range. This field is a comma separate list of values returned from the server; possible values are:

  • 01 - Authentication Available at ACS
  • 02 - Attempts Supported by ACS or DS
  • 03 - Decoupled Authentication Supported
  • 04 - Whitelisting Supported
  • 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.

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:

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 class 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:

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 class via a secure channel, the specifics of which are outside the scope of the classs. 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:

Response Handling

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

Transaction Status Description
Y Authenticated successfully
C Cardholder challenge required
N Not authenticated
A Not authenticated, but a proof of authentication attempt was generated in AuthenticationValue
U Not authenticated due to technical or other issue
R Not authenticated because the issuer is rejecting authentication
D Challenge required; decoupled authentication confirmed
I Informational only; 3DS Requestor challenge preference acknowledged

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 or D), 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:

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 classs 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 class 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.

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:

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:

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 ProtocolVersion configuration setting 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:

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 your application as the body of the HTTP response. Set the Content-Type header to application/JSON; charset=utf-8

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:

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.

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.
