Gnosis Pay offers an HTTP JSON API, fully documented using OpenAPI—you can find our specification here. This API reference is auto-generated from our OpenAPI spec, and you can also use the JSON file to generate client code in various programming languages. Most API endpoints require authentication with a JWT obtained via Sign-In with Ethereum (SIWE). For your convenience, we provide a helper app within these docs to help you generate a token and sign Safe transactions. To make API requests using the API Reference playground, simply paste your token into the Authorization Header field.
