Frequently asked questions

What to consider when designing a partner-native authentication experience.

What is Auth Pass-through?
Auth Pass-through is an integration pattern that allows a platform to securely recognize an already-authenticated customer in a connected payment experience, subject to the provider and implementation.
How does it work?
Typically, the partner backend verifies its own user and exchanges trusted session information with the payment service through server-to-server calls. The exact API design is agreed during integration.
How is the experience different?
Rather than being asked to create a separate login during checkout, an eligible signed-in customer can continue into the payment journey. Additional verification may still be required.
Is a user record still required?
A payment provider may still maintain a customer record for operational, legal and compliance requirements, even when an extra sign-in screen is not shown.
What information identifies the user?
The identifier depends on the final API contract and may include a verified partner customer ID or other agreed information. Avoid exposing sensitive identity data in client-side code.
Is an onboarding call required before checkout?
Some systems require a backend onboarding or account-linking operation before the first purchase. The sequence must be defined by the actual integration provider.
Can the browser directly exchange authentication secrets?
Sensitive trust assertions and partner credentials should remain on a verified backend, not in public browser or mobile application code.
Does this work with Google, Apple or SSO sign-in?
It can be designed to support customers who used different initial sign-in methods, provided your backend securely confirms their session and the partner integration accepts it.
Can it work in a hosted widget?
That depends on the capabilities of the chosen payment provider. Some implementations require a fully white-label checkout rather than an embedded hosted widget.
Can we migrate from an existing widget?
A migration may be possible after reviewing the provider’s authentication options, your checkout implementation and the verification requirements.
Which payment methods are supported?
Payment method availability depends on the connected gateway, jurisdictions, merchant setup and the payment integration—not on authentication continuity alone.
How should the integration be secured?
Use server-side credentials, authenticated requests, short-lived tokens, least privilege, request validation, logging and appropriate network restrictions.
Can multiple backend IP addresses be allowed?
If the integration requires IP allowlisting, multiple verified outbound IP addresses may be configured in coordination with the provider.
Is Auth Pass-through the same as KYC reliance?
No. Authentication confirms an active session; KYC verifies identity under applicable compliance rules. One does not automatically replace the other.
Is Auth Pass-through only for exchanges?
No. The same design pattern can be useful for wallets, neobanks, exchanges and remittance applications, depending on the integration architecture.
