OAuth Test Client

When working with OAuth2 services, especially when developing first-party implementations, it can be helpful to have a small client application that can test the full oauth2 flow to ensure protocol compliance and functionality.

This software should serve this purpose, providing the most minimal OAuth2 client to act as a testbed when working with OAuth implementations.

Support

This client exclusively supports the latest OAuth 2.1 flow with PKCE and an S256 challenge method. No other flows or variations of OAuth are supported.

Usage

Copy config.yaml.example to config.yaml and fill out the endpoints and credentials for your OAuth provider.

Then just run the program:

go run .

This will start an HTTP server on the configured port (default 8181). Visiting this in your browser will immediately trigger the OAuth flow.
