What Are Payment APIs?
Payment APIs are APIs (Application Programming Interfaces) designed for managing payments.
They enable eCommerce sites to process:
- credit cards,
- track orders,
- and maintain customers lists.
In many instances, they can help protect merchants from fraud and information breaches.
They can also simplify regulatory compliance.
Payment APIs can integrate multiple payment sources and provide customers with a means of tracking their payments.
Many of them permit managing recurring subscriptions.
They can also be used for maintaining lists of clients.
The most common users of online payment systems online merchants.
Publishers running blogs and selling for-pay newsletters and information may also make use of payment services.
Some APIs permit brick-and-mortar customers to take payments at a kiosk or by using an inexpensive smartphone attachment.
Before we dive in, let take a look at some important payment API definitions:
- Access Control – Systems for permitting only authorized users to view and/or change information.
