PSE Collection

Simulate PSE collection scenarios in the Banking sandbox, including bank selection, acceptance, rejection, and timeouts.

Use these test cases to validate how your integration handles PSE collection intents — bank selection, successful payments, user rejections, and network timeouts.

This page is a sandbox scaffold. The full version will include the list of available sandbox banks, deterministic test cases for each outcome, and the webhook events fired at each step.
