Payment Service Providers (PSPs)

Welcome to the Sentinal® Integration Documentation. This guide is specifically tailored for Payment Service Providers (PSPs) aiming to integrate seamlessly with the Sentinal® system. The Sentinal® API, designed around REST principles, ensures a predictable and standardized integration experience. This page will provide an overview of what PSPs are, what they need to do, and the specific API endpoints they must integrate with.

What are Payment Service Providers (PSPs)?

Payment Service Providers (PSPs) are third-party companies that provide businesses with the ability to accept various payment methods, including credit cards, bank transfers, and other payment methods. PSPs streamline the payment process by managing transactions and ensuring they are processed securely and efficiently.

Responsibilities of PSPs Integrating with Sentinal®
