Open Payments SDK grant program

This grant is open from April 1st and applicants will be reviewed on an ongoing basis.

Software development kits (SDKs) reduce the time and effort required to integrate an API like Open Payments into an app. However, creating bespoke SDKs in many programming languages requires broad expertise and duplicative maintenance effort. Tools exist to automate the creation and maintenance of SDKs, but do not yet support the latest security features used by Open Payments.

The Interledger Foundation seeks to improve the developer experience of Open Payments by funding proposals in these themes:

• Support for RFC 9635 Grant Negotiation and Authorization Protocol (GNAP) as a security scheme in the OpenAPI Specification (up to $25,000)
• Support for GNAP in the Kiota SDK generator for TypeScript, PHP, Python, and Go (up to $10,000 per language)
• Support for Rust and Ruby languages in the Kiota SDK generator (up to $25,000 per language)
• Software libraries for RFC 9421 HTTP Message Signatures (up to $5,000 per language)
• Documenting Open Payments flows in Arazzo Specification (up to $1,000)
• Support for Arazzo Specification in the Kiota SDK generator (up to $25,000)
• Support for RFC 9635 in curl (up to $10,000)
   

Open Payments is a universal HTTP API for initiating and authorizing a payment on any payment network. Any financial service provider can implement the Open Payments API to enable its customers to use Open Payments. Websites and apps then integrate Open Payments as API clients to facilitate payments on behalf of their customers.
