Using the All-in-one Workflow of the Web SDK

On this page:

Overview

The all-in-one workflow of the Web SDK is the easiest way to implement 3D Secure 2 check on your payment page without much development effort. Once added, the Web SDK performs all communication required for the 3D Secure 2 check without any manual intervention by the merchant.

You can also download and use the Web SDK demo application to understand more about these flows.

To use this workflow, perform the following steps:

  1. Complete the steps listed in the Web SDK prerequisites and installation topics.

  2. Call the web3dsFlow method. The Web SDK performs the following actions internally after you submit the cardholder’s data:

    1. Calls the lookup method

    2. Calls the deviceFingerprint method

    3. Calls the authenticate method

    4. (If substep 3 needs a challenge) Calls the challenge method

    5. (If substep 4 was called) Calls the getChallengeResult method

  3. Use authentication values received in substep 2 or substep 5 of step 2 to confirm or deny the order.

note

  • If the card used in the transaction does not support 3D Secure 2, the Web SDK triggers the 3D Secure 1.0 check if the clientStartProtocolVersion is set to 1.0.2 in the authenticate request. If the card does not support 3D Secure 1.0 as well, the Web SDK returns an error. If the transaction uses a 3D Secure 1.0 authentication flow, the Web SDK does not call the deviceFingerprint method.

  • In the all-in-one workflow, you cannot access individual responses returned by the above methods. These calls are handled internally. To access individual responses, use the toolkit workflow.

For a detailed description of these methods, see Web SDK toolkit workflow

The all-in-one flow dispatches the following events during the transaction authentication process. You can use these events to track the progress of the authentication process:

  • THREEDS/LOOKUP_START
  • THREEDS/LOOKUP_END
  • THREEDS/DEVICE_FINGERPRINT_START
  • THREEDS/DEVICE_FINGERPRINT_END
  • THREEDS/AUTHENTICATION_START
  • THREEDS/AUTHENTICATION_END
  • THREEDS/CHALLENGE_START
  • THREEDS/CHALLENGE_END
  • THREEDS/RESULT_START
  • THREEDS/RESULT_END

note

If the transaction uses a 3DS 1 authentication flow, the Web SDK does not call the DEVICE_FINGERPRINT_START and DEVICE_FINGERPRINT_END events.

Web SDK Access Credentials

You need to set up your credentials before the SDK can communicate with the 3DS Server. The Web SDK only supports JWT tokens for authentication.

For steps to get a token, see the Authentication topic.

Use the following code to set up your credentials in the Web SDK.

var sdk = new window.Elavon3DSWebSDK(
{
    baseUrl: "https://uat.gw.fraud.eu.elavonaws.com/3ds2",  // Required. URL of Elavon’s 3DS Server.
    token: "JWT TOKEN"  // Generated by using the API key to send a request for a JWT token from the 3DS Server.
});

Call the web3dsFlow method

When you call the web3dsFlow method, it returns a promise.

const response = await sdk.web3dsFlow(request)

Send an authentication request to the 3DS Server

Create an authentication request by calling the web3dsFlow function.

To enable 3DS 1 fallback when the issuer or the account number does not support 3DS 2, set the clientStartProtocolVersion to 1.0.2.

Sample authentication request with only the required parameters

note

For better chances of successful authentication, Elavon recommends that you send both required and optional parameters in the request.

Challenge Window Display Options

When a customer receives a challenge from the issuer, the Web SDK displays an iframe for them to enter information. There are two display types for the challenge window: lightbox or inline. The challengeWindowSize property works in conjunction with the challengeIframeElement and displayMode properties to display the challenge window during a challenge flow.

Lightbox

Lightbox displays a challenge window as a modal over the top of the user’s current screen. It is the default mode of presentation. You can set the lightbox display with the following settings.

{
  // example to show the display mode set to lightbox
  "meta":
  {
    "displayMode": "lightbox",        // Default display mode is lightbox
    "challengeIframeElement": null   // Optional. Container element where challenge content will be displayed within the UI.
  }
}
Inline

Inline display injects the challenge window iframe into the existing page. You can set the challenge window display to inline with the following settings.

{
  // example to show the display mode set to inline
  "meta":
  {
    "displayMode": "inline",
    "challengeIframeElement": document.getElementById('iframe-container') // Optional. Container element where challenge content will be displayed within the UI.
  }
}

The challengeWindowSize value defines the width and height (in pixels) of a container that will hold the iframe containing a challenge if requested. The default value is 05, which means the challenge window will occupy the full screen. Valid values of a challenge window size are:

  • 01 = 250 X 400
  • 02 = 390 X 400
  • 03 = 500 X 600
  • 04 = 600 X 400
  • 05 = full screen

note

You can test different authentication scenarios for supported card schemes using the test card numbers on the Test scenarios page.

3DS 2 - Sample authentication response (frictionless / no challenge)

The authenticated property in the authentication response indicates if the authentication was successful. The value is true if the issuer authenticated the transaction. The authentication response will return a message and an authenticationValue, if available.

{
  "messageType": "ARes",  // Returned as ARes in case of a frictionless flow.
  "messageVersion": "2.1.0",  // 3DS protocol version used in the authentication.
  "threeDSServerTransID": "6a719458-2b1e-4577-95e7-dd030ef79afb", // 3DS Server Transaction ID.
  "dsTransID": "bb76e30c-9c1b-421e-a905-2d84ae9c9802",  // Directory Server (DS) Transaction ID.
  "acsTransID": "da8626f4-4fdf-438d-8d31-1e252a08efca",  // Access Control Server (ACS) Transaction ID.
  "acsReferenceNumber": "ELAVON_ACS_EMULATOR_REF_NUMBER32",  // Unique identifier assigned by the EMVCo Secretariat upon Testing and Approval.
  "acsOperatorID": "ELAVON_ACS_EMULATOR_OPERATOR_ID1",    // DS assigned ACS identifier.
  "dsReferenceNumber": "ELAVON_3DS_DS_EMULATOR_REF_NUM32",  // EMVCo-assigned unique identifier to track approved DS.
  "transStatus": "Y",   // Transaction status.
  "authenticationValue": "1iqJgyBQ1/DALPHOkiluJ1HWg6g=",    // Authentication value returned by the issuer.
  "eci": "05",    // Authentication value returned by the issuer.
  "authenticated": true,  // true when authentication is successful and false when the issuer denied authentication.
  "message": "Account Verification Successful" // Result of the authentication request in a descriptive text.  
}

For a detailed description of each parameter, see Authentication parameters description

note

  • If transStatus is Y and eci and authenticationValue field values are present, the transaction is authenticated and the liability shifts to the issuer. The authenticated field is also set to true.
  • If transStatus is A and eci and authenticationValue field values are present, the transaction attempted an authentication and the liability shifts to the issuer. The authenticated field is set to false because only an authentication attempt was made; however, the presence of eci and authenticationValue field values guarantees liability shift.
  • Any other transStatus result does not result in a liability shift.

3DS 2 - Sample authentication response (challenge flow)

If the issuer needs more information from the cardholder to authenticate the cardholder, the authentication response returns the issueChallenge value as true.

{
  "messageType": "RReq",  // Returned as RReq in case the issuer challenged the user to complete the transaction.
  "messageVersion": "2.1.0",    // 3DS protocol version used in the authentication.
  "threeDSServerTransID": "9e2861d3-d9cf-4403-8e71-f5c941ba9a6b",   // 3DS Server Transaction ID.
  "dsTransID": "b30d06a3-fbd3-4767-a838-70f9e52863e8",    // Directory Server (DS) Transaction ID.
  "acsTransID": "ef958dfe-ca47-4986-824e-0b99ab33e353",   // Access Control Server (ACS) Transaction ID.
  "authenticationType": "01",    // Indicates the type of authentication method the Issuer used to challenge the cardholder.
  "authenticationValue": "QJH8cSWa0cxCr6VuL9gm4dbKGh8=",  // Authentication value returned by the issuer.
  "eci": "05",   // Electronic Commerce Indicator.
  "interactionCounter": "01",   //Indicates the number of authentication cycles attempted by the Cardholder.
  "messageCategory": "01",    //Identifies the category of the message for a specific use case. 01 = PA.
  "transStatus": "Y",   // Transaction status.
  "authenticated": true,  // Returned as false when the issuer denied authentication.
  "message": "Account Verification Successful" // Result of the authentication request in a descriptive text.  
}
