👁️‍🗨️ Auth Reliance through APIs

ℹ Overview

Auth Reliance is a Transak feature that allows partners to authenticate users without re-login into the Transak authentication flow.

❔How it works

1. The user logs in to the partner application
2. The partner authenticates the user internally
3. The partner calls Transak Whitelabel APIs using two additional headers as below:
   • Partner access token (x-access-token)
   • User's email address (x-user-identifier)
4. Transak validates the request and processes it as a partner-delegated user session.

🚧 Current Limitations & Known Constraints

• Payment Method Restrictions:

  • Supported: Bank transfers and open banking only

  • NOT Supported: Cards, Apple Pay, Google Pay

• Architecture Constraint: Server-to-server communication is limited to the partner's IP whitelisting. (This feature is not supported in frontend widgets)

䷿ Prerequisites

• Auth Reliance enabled on your API key.
• Partner access token generated using https://docs.transak.com/reference/refresh-access-token
