SelectAccount

Let customers select their bank accounts within the Trustly flow
Updated 8 days ago

Overview

Initiates a new order where customers can select and verify one of their bank accounts.

You can find more information about how to present the Trustly URL in Trustly URL presentation.

When the account has been verified an Account notification is immediately sent to the NotificationURL.

A typical flow is:

  1. The merchant makes an API-call to SelectAccount and redirects the end-user to the url.

  2. The end-user selects his/her bank and completes the identification process.

  3. The end-user is redirected back to the merchant at the SuccessURL, note that the account might not be verified yet at this point.

  4. When the account is verified, Trustly sends an Account notification to the merchant's system with information about the selected account
