We are trying to make payments by means of a link following the steps indicated here: link
We are implementing a 'marketplace type' system where 'common' users can pay 'seller' users.
Initially, payments were made correctly. We are using the following stack:
- A web application with the checkout button
- A backend in rails associated with an ACCESS_TOKEN (the seller + the marketplace)
- Visa Debit Card (4002 7686 9439 5619)
The first payments were issued well, but, after some tests, all payments (common and sandbox) with any card, began to fail.
We thought it was a problem with the application, therefore, we created a new application , but we kept coming to a page "We had a problem, try again"
We are waiting for answers. Of course, thank you very much!
