On this page we will share what you can expect when integrating with Visa Payment Passkey Service (VPPS).

Before Integration

To ensure a seamless integration to Visa Payment Passkey Service be sure to have the following prepared:

  • The user's device must have platform authenticators such as Face ID or Touch ID. Currently, VPPS does not provide support to roaming authenticators such as YubiKey.

  • The browser being used must have WebAuthN API support.

  • The integrator must support the Data Exchange API.

  • For browser flows, VPPS is only supported for Cardinal Cruise API. For app flows, when using Web SDK, integrators would need to consider implementation of iframes in their checkout flow.

During Integration

You will need to complete the following steps:

  1. Check FIDO Compatibility

  2. Check for VPPS Enrollment

  3. Enroll a User into VPPS

  4. Authenticate using VPPS

FIDO API Support

The user’s browser will also need to be compatible with the FIDO API. The API has two core components explained in the table below:
