The Client module is designed for use on mobile devices and facilitates EMV® 3-D Secure authentication.

Syntax

IPWorks3DS.Client

Remarks

The Client class is a counterpart to the 3DS Server class. It is designed for use on mobile devices and supports operations that facilitate EMV® 3-D Secure authentication in both frictionless and challenge flows.

Preparing the Authentication Request

To begin, device specific information must be collected and prepared for transmission to the directory server. This can be done by calling the AddDeviceParam method. Consult the EMV® 3-D Secure Specifications for more details about applicable device parameters for each particular operating system.

The GetAuthRequest method is used to obtain the request message to be send to the directory server. GetAuthRequest encrypts the device info and prepares all the data necessary to be sent by the 3DS Server class in the SendAuthRequest method.

After calling this method, the returned data must be transmitted via a separate secure channel to the server where 3DS Server is being used.

The following properties are required before calling the method:

Calling this method returns required information used by 3DS Server to send the authentication request. Transmit the value returned by this method to the system where 3DS Server is used. The method used to transmit this value is outside the scope of the class.

See SendAuthRequest for details on sending the authentication request after transmitting the data to the 3DS Server.

Calling this method also populates SDKTransactionId which uniquely identifies this transaction and must be used in subsequent calls relating to this transaction, such as SendChallengeRequest.

Interaction With the 3DS Server Class

As mentioned above, the request to the Directory Server must be made by the 3DS Server class which resides on a server under control of the merchant. A web server is required even for app-based authentication both to send the authentication request and to be notified of authentication results later in the flow.

It is expected that a secure channel can be established between the app using the Client class and the server where the 3DS Server class resides in order to transfer information freely.

Sending the Authentication Request

The act of sending the authentication request takes place with the 3DS Server class.

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 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 CardRangesMethodURL has been set by the ACS. Card range data may be retrieved by calling RequestCardRanges.

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

If a CardRangesMethodURL 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 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.

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

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.

Processing the Authentication Response

After the response to the authentication request is received from the 3DS Server class, call CheckAuthResponse to verify and parse the response. See the 3DS Server's SendAuthRequest method for details about obtaining the response.

Before calling this method, ACSRootCerts must be populated with the root certificates used by the ACS to sign the response. This method will validate the signature of the signed content if present.

After calling this method, inspect TransactionStatus to determine if the transaction requires a challenge. If TransactionStatus is C, a challenge is required and SendChallengeRequest should be called to proceed with the challenge flow. If TransactionStatus is D, decoupled authentication will take place outside of the 3-D Secure flow and the results will be posted to the 3DS Server.

If TransactionStatus is Y or A, the transaction is complete.

Challenge Interaction

If TransactionStatus is C, a challenge is required. The challenge takes place between the cardholder and the ACS. During this interaction the class will communicate directly with the ACS from the app where it is used to exchange information.

SendChallengeRequest begins the challenge flow. SendChallengeRequest sends the Challenge Request to the ACS when a challenge is required.

When the TransactionStatus is C after calling CheckAuthResponse, a challenge to the cardholder is required. This method sends the challenge request and parses the response. The ACS may provide multiple challenges to the cardholder during this process. As a result this method may need to be called multiple times throughout the authentication process.

After this method is called, check ChallengeComplete to determine if the challenge process is complete. If it is complete (True), check TransactionStatus to determine the outcome. If ChallengeComplete is False, additional challenge interaction is required.

First Request

The first time this method is called, information about the required challenge is obtained from the ACS. The ACS connection information is automatically set when CheckAuthResponse is called; there is no need to specify any ACS connection information.

All required properties for the first call to this method are automatically set after CheckAuthResponse is called. If the transaction has been canceled, set ChallengeCancellationIndicator to inform the ACS.

After calling this method, the ACS will respond with details about the challenge to be presented to the cardholder. The ACSUIType property indicates the way the ACS will interact with the cardholder. The ChallengeComplete property will be False after the first call to this method since the challenge interaction is not yet complete.

The following properties are applicable when ACSUIType is Text (01), Single-Select (02), or Multi-Select (03):

• ChallengeSelectInfo
• ChallengeInfoHeader
• ChallengeInfoLabel
• ChallengeInfoText
• EnableChallengeInfoTextIndicator
• ExpandableInformationLabel
• ExpandableInformationText
• IssuerImage1
• IssuerImage2
• IssuerImage3
• PaymentSystemImage1
• PaymentSystemImage2
• PaymentSystemImage3
• ResendInformationLabel
• SubmitAuthenticationLabel
• WhyInformationLabel
• WhyInformationText

Use the values in the above properties to populate values in the native UI in the app. The UI must follow the guidelines defined in the EMV® 3-D Secure specification.

The following properties are applicable when ACSUIType is Out-of-Band (04):

• ChallengeAdditionalInformation
• ChallengeInfoHeader
• ChallengeInfoLabel
• ChallengeInfoText
• EnableChallengeInfoTextIndicator
• ExpandableInformationLabel
• ExpandableInformationText
• IssuerImage1
• IssuerImage2
• IssuerImage3
• OOBContinueLabel
• PaymentSystemImage1
• PaymentSystemImage2
• PaymentSystemImage3
• ResendInformationLabel
• WhyInformationLabel
• WhyInformationText

Use the values in the above properties to populate values in the native UI in the app. The UI must follow the guidelines defined in the EMV® 3-D Secure specification.

The following properties are applicable when ACSUIType is HTML (05):

• ACSHTML
• ACSHTMLRefresh

In the case of an HTML interaction, the app should create a webview and populate this with the HTML in ACSHTML.

As per the EMV® 3-D Secure specification, the HTML UI is presented to the cardholder via a web view which remains in control of the app. The app must intercept any remote URL requests made from within the web view, and instead handle them within the app. Preventing the cardholder from making requests in the web view to another server is critical to the security of the environment. According to the EMVCo specification, intercepting these requests has two effects:

• Prevents malicious HTML from redirecting a user to a phishing site.
• Conceptually puts the web view form under the control of the ACS, rather than the app.

• Navigation attempts from within the web view must be captured by the app and handled internally. This includes all requests including images, javascript files, css, etc.
• The web view element is not utilized as a browser, but as a UI element whose content is provided by the ACS.

Second Request

The second time this method is called, the purpose is to provide a response to the ACS. At this point the customer should have responded to the challenge provided by the ACS in the response to the first call. If the transaction has been canceled, set ChallengeCancellationIndicator to inform the ACS. The following properties are applicable when calling this method the second time:

• ChallengeDataEntry
• OOBContinuationIndicator

When ACSUIType is Text (01) or HTML (05), set ChallengeDataEntry to the data exactly as it was specified by the cardholder. Do not format or otherwise change the data.

When ACSUIType is Single-Select (02), set ChallengeDataEntry to the name of the selected option. For instance the ACS may provide the user with a selection like:

mobile: **** **** 329
email: s******k**@g***.com

When ACSUIType is Multi-Select (03), set ChallengeDataEntry to a comma-separated list of names of the selected options. For instance if ChallengeSelectInfo contains elements with names like chicago_illinois, st_louis_missouri, and portland_oregon, and the user chose two options, the value specified in ChallengeDataEntry would be chicago_illinois,portland_oregon.

When ACSUIType is OOB (04), set OOBContinuationIndicator to True to indicate the cardholder has pressed the button signaling their completing of the OOB process.

Completing the Challenge

After calling SendChallengeRequest a second time with the cardholder's responses, the ACS may require additional challenges. Check the ChallengeComplete property to determine if the challenge is complete. If False, more challenges are required by the ACS and the same process of displaying the challenge info, collecting the response, and submitting it to the ACS should be performed again.

If ChallengeComplete is True, the challenge interaction is complete and TransactionStatus can be inspected to determine whether the transaction was successful.

Note: As part of the challenge completion the ACS also notifies the 3DS Server of the results. This is done by posting the results to the URL defined by the ResultsURL property of the 3DS Server class.

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"

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.

- (void)setSSLAcceptServerCertEncodedB :(NSData*)newSSLAcceptServerCertEncoded;
 

Default Value

""

Remarks

If it finds any issues with the certificate presented by the server, the class will normally terminate the connection with an error.

You may override this behavior by supplying a value for SSLAcceptServerCert. If the certificate supplied in SSLAcceptServerCert is the same as the certificate presented by the server, then the server certificate is accepted unconditionally, and the connection will continue normally.

Note: This functionality is provided only for cases in which you otherwise know that you are communicating with the right server. If used improperly, this property may create a security breach. Use it at your own risk.

This property is read-only.

- (void)setTimeout :(int)newTimeout;

Default Value

30

Remarks

If the Timeout property is set to 0, all operations will run uninterrupted until successful completion or an error condition is encountered.

If Timeout is set to a positive value, the class will wait for the operation to complete before returning control.

The class will use DoEvents to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not freeze and remains responsive.

If Timeout expires, and the operation is not yet complete, the class .

Note: By default, all timeouts are inactivity timeouts, that is, the timeout period is extended by Timeout seconds when any amount of data is successfully sent or received.

The default value for the Timeout property is 30 seconds.

TogglePositionIndicator Property (Client Module)

AddDeviceParam Method (Client Module)

Adds a device parameter to the collection.

Syntax

• Swift
• Objective-C

public func addDeviceParam(field: String, value: String, valueType: Int32, category: Int32) throws -> Void

- (void)addDeviceParam:(NSString*)field :(NSString*)value :(int)valueType :(int)category;

Remarks

AddDeviceParam adds a new device parameter to the DeviceParams collection. These parameters should be obtained from the consumer device and a full list of available parameters can be found in the EMV® 3-D Secure SDK-Device Information document provided by EMVCo.

The ValueType parameter specifies the type of the value. Possible values are:

• 1 (Array)
• 2 (String)

Most parameters will have a value type of 2 (String), which will contain a single, string value. Some parameters, however, may require an array of strings. For example, the A040 parameter is defined as containing a set of paired Bluetooth devices. All of these devices can be specified via an array like so: client.addDeviceParam("A040", "[\"firstDevice\", \"secondDevice\", \"thirdDevice\"]", 1, 1);

There are four categories of device information parameters:

DV - Data Version

This is the version of the data being specified. This is 1.0 by default, but can be set to a different value as shown below. When setting the data version, only the value of the parameter needs to be specified. client1.AddDeviceParam("", "1.1", 2, 0);

DD - Device Data

This category is used to specify the device parameters collected from the mobile platform. // the device platform is Android client1.AddDeviceParam("C001", "Android", 2, 1); // the device model is an HTC One (M8) client1.AddDeviceParam("C002", "HTCOne_M8", 2, 1);

DPNA - Device Parameter Not Available

This category is used to specify reasons for unavailable device parameters. // IP Address couldn't be specified because of a "market or regional restriction on the parameter." client1.AddDeviceParam("C010", "RE01", 2, 2);

SW - Security Warning

This category of parameter is used to specify security warnings. These are used to let the directory server know of the result of checks made by the application upon initialization. When setting security warning parameters, only the name of the parameter needs to be specified. // the device is jailbroken client1.AddDeviceParam("SW01", "", 2, 3); // A debugger is attached to the app client1.AddDeviceParam("SW04", "", 2, 3);

AddExtension Method (Client Module)

Adds an extension to the collection.

Syntax

• Swift
• Objective-C

public func addExtension(id: String, name: String, critical: Bool, data: String) throws -> Void

- (void)addExtension:(NSString*)id :(NSString*)name :(BOOL)critical :(NSString*)data;

Remarks

Data necessary to support requirements not otherwise defined in the 3-D Secure message are carried in Message Extensions. AddExtension adds a new extension to the Extensions collection.

Note: The maximum number of extensions is 10.

AddRequestField Method (Client Module)

Adds a field to the data in the request.

Syntax

• Swift
• Objective-C

public func addRequestField(name: String, value: String, valueType: Int32) throws -> Void

- (void)addRequestField:(NSString*)name :(NSString*)value :(int)valueType;

Remarks

This method can be used to extend the requests constructed by the class. When this method is called, the component will add the specified field to the end of the request.

CheckAuthResponse Method (Client Module)

Checks the received packet.

Syntax

• Swift
• Objective-C

public func checkAuthResponse(authResponse: String) throws -> Void

- (void)checkAuthResponse:(NSString*)authResponse;

Remarks

After the response to the authentication request is received from the 3DS Server class, call CheckAuthResponse to verify and parse the response. See the 3DS Server's SendAuthRequest method for details about obtaining the response.

Before calling this method, ACSRootCerts must be populated with the root certificates used by the ACS to sign the response. This method will validate the signature of the signed content if present.

After calling this method, inspect TransactionStatus to determine if the transaction requires a challenge. If TransactionStatus is C, a challenge is required and SendChallengeRequest should be called to proceed with the challenge flow. If TransactionStatus is D, decoupled authentication will take place outside of the 3-D Secure flow and the results will be posted to the 3DS Server.

If TransactionStatus is Y or A, the transaction is complete.

Config Method (Client Module)

Sets or retrieves a configuration setting.

Syntax

• Swift
• Objective-C

public func config(configurationString: String) throws -> String

- (NSString*)config:(NSString*)configurationString;

Remarks

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

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, 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.

GetAuthRequest Method (Client Module)

Prepares data to be sent by the 3DS Server.

Syntax

• Swift
• Objective-C

public func getAuthRequest() throws -> String

- (NSString*)getAuthRequest;

Remarks

GetAuthRequest encrypts the device info and prepares all the data necessary to be sent by the 3DS Server class in the SendAuthRequest method.

After calling this method, the returned data must be transmitted via a separate secure channel to the server where 3DS Server is being used.

The following properties are required before calling the method:

Calling this method returns required information used by 3DS Server to send the authentication request. Transmit the value returned by this method to the system where 3DS Server is used. The method used to transmit this value is outside the scope of the class.

See SendAuthRequest for details on sending the authentication request after transmitting the data to the 3DS Server.

Calling this method also populates SDKTransactionId which uniquely identifies this transaction and must be used in subsequent calls relating to this transaction, such as SendChallengeRequest.

Interrupt Method (Client Module)

Interrupts the current action.

Syntax

• Swift
• Objective-C

public func interrupt() throws -> Void

- (void)interrupt;

Remarks

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

Reset Method (Client Module)

Clears all properties to their default values.

Syntax

• Swift
• Objective-C

public func reset() throws -> Void

- (void)reset;

Remarks

This method clears all properties to their default values.

ResetTransactionInfo Method (Client Module)

Resets transaction specific information.

Syntax

• Swift
• Objective-C

public func resetTransactionInfo() throws -> Void

- (void)resetTransactionInfo;

Remarks

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

In an App-Based flow the following are reset:

• Internal ephemeral encryption keys
• Values added by AddRequestField
• ACSHTML
• ACSHTMLRefresh
• ACSUIType
• ChallengeAdditionalInformation
• ChallengeComplete
• ChallengeDataEntry
• ChallengeInfoHeader
• ChallengeInfoLabel
• ChallengeInfoText

SendChallengeRequest Method (Client Module)

Builds and sends the Challenge Request in an app-based challenge flow.

Syntax

• Swift
• Objective-C

public func sendChallengeRequest() throws -> Void

- (void)sendChallengeRequest;

Remarks

SendChallengeRequest sends the Challenge Request to the ACS when a challenge is required.

When the TransactionStatus is C after calling CheckAuthResponse, a challenge to the cardholder is required. This method sends the challenge request and parses the response. The ACS may provide multiple challenges to the cardholder during this process. As a result this method may need to be called multiple times throughout the authentication process.

After this method is called, check ChallengeComplete to determine if the challenge process is complete. If it is complete (True), check TransactionStatus to determine the outcome. If ChallengeComplete is False, additional challenge interaction is required.

First Request

The first time this method is called, information about the required challenge is obtained from the ACS. The ACS connection information is automatically set when CheckAuthResponse is called; there is no need to specify any ACS connection information.

All required properties for the first call to this method are automatically set after CheckAuthResponse is called. If the transaction has been canceled, set ChallengeCancellationIndicator to inform the ACS.

After calling this method, the ACS will respond with details about the challenge to be presented to the cardholder. The ACSUIType property indicates the way the ACS will interact with the cardholder. The ChallengeComplete property will be False after the first call to this method since the challenge interaction is not yet complete.

The following properties are applicable when ACSUIType is Text (01), Single-Select (02), or Multi-Select (03):

• ChallengeSelectInfo
• ChallengeInfoHeader
• ChallengeInfoLabel
• ChallengeInfoText
• EnableChallengeInfoTextIndicator
• ExpandableInformationLabel
• ExpandableInformationText
• IssuerImage1
• IssuerImage2
• IssuerImage3
• PaymentSystemImage1
• PaymentSystemImage2
• PaymentSystemImage3
• ResendInformationLabel
• SubmitAuthenticationLabel
• WhyInformationLabel
• WhyInformationText

Use the values in the above properties to populate values in the native UI in the app. The UI must follow the guidelines defined in the EMV® 3-D Secure specification.

The following properties are applicable when ACSUIType is Out-of-Band (04):

• ChallengeAdditionalInformation
• ChallengeInfoHeader
• ChallengeInfoLabel
• ChallengeInfoText
• EnableChallengeInfoTextIndicator
• ExpandableInformationLabel
• ExpandableInformationText
• IssuerImage1
• IssuerImage2
• IssuerImage3
• OOBContinueLabel
• PaymentSystemImage1
• PaymentSystemImage2
• PaymentSystemImage3
• ResendInformationLabel
• WhyInformationLabel
• WhyInformationText

Use the values in the above properties to populate values in the native UI in the app. The UI must follow the guidelines defined in the EMV® 3-D Secure specification.

The following properties are applicable when ACSUIType is HTML (05):

• ACSHTML
• ACSHTMLRefresh

In the case of an HTML interaction, the app should create a webview and populate this with the HTML in ACSHTML.

As per the EMV® 3-D Secure specification, the HTML UI is presented to the cardholder via a web view which remains in control of the app. The app must intercept any remote URL requests made from within the web view, and instead handle them within the app. Preventing the cardholder from making requests in the web view to another server is critical to the security of the environment. According to the EMVCo specification, intercepting these requests has two effects:

• Prevents malicious HTML from redirecting a user to a phishing site.
• Conceptually puts the web view form under the control of the ACS, rather than the app.

• Navigation attempts from within the web view must be captured by the app and handled internally. This includes all requests including images, javascript files, css, etc.
• The web view element is not utilized as a browser, but as a UI element whose content is provided by the ACS.

Second Request

The second time this method is called, the purpose is to provide a response to the ACS. At this point the customer should have responded to the challenge provided by the ACS in the response to the first call. If the transaction has been canceled, set ChallengeCancellationIndicator to inform the ACS. The following properties are applicable when calling this method the second time:

• ChallengeDataEntry
• OOBContinuationIndicator

When ACSUIType is Text (01) or HTML (05), set ChallengeDataEntry to the data exactly as it was specified by the cardholder. Do not format or otherwise change the data.

When ACSUIType is Single-Select (02), set ChallengeDataEntry to the name of the selected option. For instance the ACS may provide the user with a selection like:

mobile: **** **** 329
email: s******k**@g***.com

When ACSUIType is Multi-Select (03), set ChallengeDataEntry to a comma-separated list of names of the selected options. For instance if ChallengeSelectInfo contains elements with names like chicago_illinois, st_louis_missouri, and portland_oregon, and the user chose two options, the value specified in ChallengeDataEntry would be chicago_illinois,portland_oregon.

When ACSUIType is OOB (04), set OOBContinuationIndicator to True to indicate the cardholder has pressed the button signaling their completing of the OOB process.

Completing the Challenge

After calling SendChallengeRequest a second time with the cardholder's responses, the ACS may require additional challenges. Check the ChallengeComplete property to determine if the challenge is complete. If False, more challenges are required by the ACS and the same process of displaying the challenge info, collecting the response, and submitting it to the ACS should be performed again.

If ChallengeComplete is True, the challenge interaction is complete and TransactionStatus can be inspected to determine whether the transaction was successful.

Note: As part of the challenge completion the ACS also notifies the 3DS Server of the results. This is done by posting the results to the URL defined by the ResultsURL property of the 3DS Server class.

DataPacketIn Event (Client Module)

Fired when receiving a data packet from the server.

Syntax

• Swift
• Objective-C

func onDataPacketIn(dataPacket: Data)

- (void)onDataPacketIn:(NSData*)dataPacket;

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 (Client Module)

Fired when sending a data packet to the server.

Syntax

• Swift
• Objective-C

func onDataPacketOut(dataPacket: Data)

- (void)onDataPacketOut:(NSData*)dataPacket;

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.

Error Event (Client Module)

Information about errors during data delivery.

Syntax

• Swift
• Objective-C

func onError(errorCode: Int32, description: String)

- (void)onError:(int)errorCode :(NSString*)description;

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 (Client Module)

Fires once for each log message.

Syntax

• Swift
• Objective-C

func onLog(logLevel: Int32, message: String, logType: String)

- (void)onLog:(int)logLevel :(NSString*)message :(NSString*)logType;

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"

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.

SSLServerAuthentication Event (Client Module)

Fired after the server presents its certificate to the client.

Syntax

• Swift
• Objective-C

func onSSLServerAuthentication(certEncoded: Data, certSubject: String, certIssuer: String, status: String, accept: inout Bool)

- (void)onSSLServerAuthentication:(NSData*)certEncoded :(NSString*)certSubject :(NSString*)certIssuer :(NSString*)status :(int*)accept;

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 (Client Module)

Fired when secure connection progress messages are available.

Syntax

• Swift
• Objective-C

func onSSLStatus(message: String)

- (void)onSSLStatus:(NSString*)message;

Remarks

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