Most payment products assume a person is clicking pay. A program is not that. You would not hand it your card.
Rill keeps those apart. You put money in with a card. Then you set a limit. The program can only spend inside that limit.
It pays a pay link. Not your homepage. After it pays, it gets what that link promised.
You can try this in test first. Same idea. The money is not real until you switch.
A person puts the money in. A program spends it under a cap.
