What you’re describing is probably being detected and flagged as fraud or money laundering by software. If they didn’t have protection in place this would be abused. You can use test credit cards.

They have obligations to shareholders to not allow fraud because that is their entire business on the line. I would assume their end of the integration is more like electricity and always on/working and if there are issues I’d be looking at my code first.
