In-app authentication

In-app authentication is an ID&V method where the End User authenticates in the issuer application.

After authentication, you can activate the digital card in two ways:

1

Activate using the issuer backend

The token requestor passes the digitalCardId to the issuer application.

The issuer application calls the issuer backend.

The issuer backend activates the digital card using the D1 API (see Resume digital card API).

2

Activate using the D1 SDK

Use the D1 SDK in the issuer application to activate the digital card directly.

This requires integrating the D1 SDK in the issuer application. For this, please check details at in-app authentication section for the functionality offered in the context of the Push Provisioning service.

In both cases, the issuer application must be launched by the token requestor and receive a digitalCardId.

This app-to-app integration is payment network-specific. Please refer to the guideline Integrate in-app ID&V for xPay and coordinate with the Thales delivery team.
