Best API to accept payments
Looking for information on how to design a good API to accept payments? Many of the considerations are the same as building an API. You must build upon sensible verbs, abstractions and data structures that are easy to understand and composable.
An application program interface (API) is a set of instructions — including tools, protocols, and routines — for building a software application. The API determines how the software pieces interact.

But what does your company need to know to design a good payments API?
Consider these three things:
- You don’t get to define the world. When designing a payment API, many of the fundamental objects like credit cards and ACH debits as well as operations like authorizations and refunds matter. Your programming team has to work with all these objects to determine for themselves whether reasoning happens at the server, application or cluster level, for example.
- There’s a lot you don’t have to do. There’s a lot of legacy code out there, but you don’t have to follow rules of the past. Since you’re in a position to think things through from the beginning, you can figure out what processes to throw away – and what’s essential.
- Users will know right away if you do a good job. Users know what they need from a payments API, and it’s hard to implement something without someone noticing almost immediately. After all, you’re working with money, and customers at every level will quickly tell you if the fund isn’t moving correctly. You must design the API while not duplicating the mistakes of the past, a tricky balance.
