Auth Reliance | Transak | Documentation

Auth Reliance allows partners to authenticate users without requiring them to re-login into the Transak authentication flow. This feature is exclusively available for Whitelabel API integrations.

Problem Statement

Integrating third-party payment services often forces users to create separate accounts and log in multiple times, disrupting the user experience and increasing friction in the conversion funnel.

Here are some of the key challenges with traditional authentication flows in payment integrations:

Redundant authentication

Users must re-authenticate with third-party services even though they’re already logged into your platform.

Higher drop-off rates

Additional authentication steps create friction points that lead to user abandonment and lower conversion rates.

Poor user experience

Users are confused about why they need to create yet another account or log in again during payment flows.

Slower transaction flows

Multiple login steps add unnecessary delays to time-sensitive payment transactions.

Our Solution

Auth Reliance eliminates redundant logins by allowing partners to pass authenticated user credentials directly to Transak, creating a seamless, uninterrupted payment experience.

Here are some of the key benefits of the Auth Reliance solution:

Seamless Authentication

Users stay authenticated without re-entering credentials or creating new accounts.

Higher Conversion

Reduce friction and drop-offs by eliminating redundant authentication steps.

Better UX

Keep users in your app’s flow without disrupting their journey.

Backend Security

Server-to-server authentication with IP whitelisting ensures secure transactions.

How does it work?
