3DS 2 Migration Guide - EMV 3DS 2 SDK Cards Integration

Watch Out!You must have a PCI compliance certificate to enable this feature on your account.

EMV 3DS 2 SDK

The 3DS 2 protocol mandates the integration of an EMV 3DS SDK for processing authentication via in-app flow. This SDK provides capabilities to authenticate processes in the native app UI without redirection to the bank ACS page for cardholder authentication. This improves the overall customer experience. EMV 3DS 2 authentication allows you to:

Collect and pass additional device data to Issuer ACS for risk assessment. In the case of cross-border payments, issuer ACS can use the data passed to decide between frictionless or challenge-based authentication flow.

Watch Out!RBI mandates the challenge flow in India, and hence the issuer cannot opt for frictionless authentication for Indian cards.

If the issuer decides to invoke the challenge-based authentication flow, then you can use the SDK to open the in-app native challenge page, to collect authentication details like OTP instead of redirecting the users.

Integration Steps

Razorpay will provide a ready-to-use 3DS 2 SDK certified by EMVCo. You may use this SDK to process 3DS 2 payment providers, including Razorpay. The SDK-based flow will vary for both Challenge-based and Frictionless authentication flows.

Handy Tips

You may also develop the same and get the SDK certified with the EMVCo.

It should contain the below fields. crv mandatory : string Indicates the curve. kty mandatory : string Indicates the key type. x mandatory : string X coordinate of the curve. y mandatory : string Y coordinate of the curve. authentication_channel mandatory : string This value is used for processing the transaction as an sdk-based flow. The constant value should be app for the SDK transaction. auth_step mandatory : string This value is an indicator for Razorpay to process the authenticate the payment.

Response Parameters

threeDSServerTransID : string Sent by DS via ACH to check the validation of the transaction at each step. acs_transaction_id : string Transaction id used by ACS to identify the transaction. acs_reference_number : string Reference number used by ACS to identify the transaction. acs_signed_content : string Signed (encrypted) response sent by ACS. acs_rendering_type : string Contains Layout rendering information.

Watch Out!

initiate_challenge_via_sdk indicates that the issuer bank has requested a challenge flow.
This challenge flow has to be processed via SDK.

4. Present the Challenge Flow to the Cardholder

In the previous API, if you receive the value of action as initiate_challenge_via_sdk, it means that the challenge flow is required. There are two ways you can use the SDK to process the challenge flow:

Using Razorpay’s EMVCo SDK
Using Direct EMVCo SDK

Using Razorpay EMVCo SDK

Given below is the SDK call to be made to collect 3DS 2 device information:

Initiate the process_challege method.
Provide the data received in the previous API response to the SDK. The parameters required are:
1. directory_server_transaction_id
2. acs_transaction_id
3. acs_reference_number
4. acs_signed_content
5. 3ds_requestor_app_url

Handy Tips

3ds_requestor_app_url- You will not get this parameter in the API response, and you need to pass your app redirection URL to this parameter.

challenge_status

Using Standalone EMVCo SDK

Given below is the SDK call to be made to collect 3DS 2 device information:

Create an instance of `ChallengeParameters`.

Create an instance of ChallengeParameters.

You will need to call the `dochallenge` method.

You will need to call the dochallenge method.

Your app provides the following to the SDK:

directory_server_transaction_id
acs_transaction_id
acs_reference_number
acs_signed_content
3ds_requestor_app_url
challenge_status

Call the `cleanup` method to free up resources.

Call the cleanup method to free up resources.

5. Verify Payment Status on Razorpay Server

You can use your existing integration to verify payment status. Such as:

Poll Payment APIs to check the payment status. This API needs to be hit in a cron job, as payment will get authorized once this API is hit for the first time. And the payment status change will show up on subsequent calls.
Listening to payment callback events or webhooks.
