Transaction linking

For clients using Certta SDKs who subsequently create transactions to perform additional validations, it is crucial to link the session tokens with these transactions to ensure full traceability of the user journey.

This process applies exclusively to clients who use both the SDK for a user session and the API for subsequent validations. If you only use our APIs directly, this step is not necessary.

This linkage is done by sending the Mobile Token (Session Token) at the time of transaction creation. Specifically, include the mobile token in the request body using the parameter referenceToken when calling the endpoint.

Check out Transaction Creation Integration for more details on how to create transactions.

By associating the transaction with the mobile token, you enable a complete audit trail that connects user authentication sessions with subsequent transaction validations, enhancing security and monitoring capabilities.
