Enroll cards by D1 API

Overview

This page explains how the issuer backend can enroll a card and its end user in Click to Pay by calling the D1 API Click to Pay enrol.

Use this backend flow when you want to orchestrate Click to Pay enrollment from the issuer backend without relying on the issuer application to call the API directly.

Key points

• The issuer backend must already know the end user's personal and card details.

• The enrollment is an asynchronous operation. The final result can be retrieved by either:

  • calling the standard getter operation, or

  • enabling D1 backend notifications (check the API summary).

• The TSP associated with the payment network triggers the usual digitization flow. The issuer backend continues to manage this flow as usual; no changes are required. Because Click to Pay applies to e-commerce transactions, approval is generally expected.

This API does not support bulk enrollments. If you need to perform mass enrollment of cards in the Click to Pay service, use batch file registration with Click to Pay auto enrollment.
