Open Payments

What is Open Payments?

Open Payments is an open API standard that can be implemented by account servicing entities (e.g. banks, digital wallet providers, and mobile money providers) to facilitate interoperability in the setup and completion of payments for different use cases including:

  • Web Monetization
  • Tipping/Donations (low value/low friction)
  • eCommerce checkout
  • P2P transfers
  • Subscriptions
  • Invoice Payments

An Open Payments server runs two sub-systems, a resource server which exposes APIs for performing functions against the underlying accounts and and authorisation server which exposes APIs compliant with the GNAP standard for getting grants to access the resource server APIs.

This repository hosts the Open API Specifications of the two APIs which are published along with additional documentation at https://openpayments.guide.

Additionally, this repository also contains three published libraries:

The code for the landing page is in ./docs.
