An application program interface (API) is a set of instructions used to build a software application. If you are interested in building an application program, you need to be sure to use logical data structures and sensible verbs that are easy to understand. Building a payments API is no different. Here are some things you need to consider when building a payments API.
- A lot of things are predefined. Things like credit cards, ACH debits, authorizations, and refunds have already been defined and your team needs to be able to work with these things.
- You don’t have to do everything. It’s not necessary to follow the old legacy code rules. Because you’re building from the ground up, you can decide what is really essential and what processes are unnecessary.
- It’s easy to tell when you’ve done a good job. When your business is money, your users will be quick to let you know when something isn’t working as it should. You need to design a predictable API that functions better than old systems.
The UniPay payment gateway from United Thinkes was built from the ground up so that it works smoothly and integrates seamlessly. If you want a good payments API, UniPay may be the answer.
