Why Your Sandbox Payments Stay in "PENDING" Status
When testing open banking payments through the Bank Modelo Sandbox, you'll notice that all payment requests remain in a "PENDING" state. This is normal and expected behavior.
How the Sandbox Works
The Bank Modelo Sandbox is specifically designed to allow developers and users to test their payment integration flows without processing actual transactions. This environment intentionally keeps payments in the "PENDING" state to:
Verify that your payment requests are properly formatted
Confirm that banking information is correct
Test the application's handling of the initial payment response
Simulate the user journey up to the authorization point
