# OpenAPI 3.1.0 Specification

An [OpenAPI specification](https://github.com/gr4vy/gr4vy-openapi) is provided for a large part of the API, including all endpoints required for payment processing.
This specification is automatically generated when new features are released, and is used to drive automatic changes to the [server-side SDKs](/guides/get-started#sdks-%26-plugins),
[CLI](/guides/tools/cli), and [Postman collection](/guides/tools/postman).
