Payments API
The PaySimple Payments API is a high-performance, scalable REST API purpose-built for partners requiring payment gateway functionality. It is the quickest way for you to begin payment acceptance, and for most businesses, this is our standard recommendation. To view our Payments API Guides and API Reference, please select v2019 in the dropdown in the upper left corner of this page.

API 4 and API 5
API 4 is our full-featured legacy API. This API is customer-centric and best suited for businesses that need additional features that are not supported in our Payments API. API 4 will continue to be fully supported and maintained for the foreseeable future. API 5 is another API that builds upon API 4 features. API 4 and API 5 will be used in conjunction for some functionality, such as Authorization.
API 4 and API 5 Guides can all be found on this page, in the left navigation.
API 4 Endpoints - See API Reference tab on the top of this page.
