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 an 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.dev.

Additionally, this crate contains several modules:

• client contains a Rust client to make requests via the Open Payments API.
• types contains Rust types for the API.
• snippets contains examples of Rust client usage for getting accustomed to the Open Payments flow.
• http_signature provides tools for working with HTTP Message Signatures.
