Token endpoint
A token endpoint is an authorization server endpoint where a client exchanges an authorization grant or credential for access tokens.
Software Security for Developers
A token endpoint is an OAuth endpoint that accepts an authorization grant and issues access tokens or other tokens.
- How it is used
- Exchanges an authorization code for access and identity tokens during an OpenID Connect login flow.
- How deep it goes
- Demonstrates endpoint discovery, browser authorization, cURL exchange, and response inspection without detailing server internals.
- Examples
- Uses localhost endpoint discovery, a browser authorization request, a returned code, a cURL token request, and a JSON token response.
- What you can do after
- Operate a token endpoint through a documented authorization-code request and interpret its token response.

Secure APIs
A token endpoint is an authorization server endpoint that exchanges an authorization grant for an access token.
- How it is used
- Exchanges an authorization code for an access token after the user authenticates and grants consent.
- How deep it goes
- Explains the endpoint’s role, discovery, required parameters, encoding, and a focused FastAPI implementation.
- Examples
- Uses an Auth0 token URL, a FastAPI GET /token endpoint, form-encoded parameters, and interactive API documentation.
- What you can do after
- Apply it via FastAPI and requests to exchange an authorization code for an access token.
Spring Security in Action, Second Edition
A token endpoint is an OAuth endpoint where a client exchanges a grant or credential for tokens.
- How it is used
- Exchanges an authorization code for tokens after user authentication, enabling client access to protected resources.
- How deep it goes
- Explains the POST request, authentication, required parameters, matching rules, and token response, but not endpoint implementation.
- Examples
- Uses a localhost cURL request with HTTP Basic authentication and a JSON response containing an access token and ID token.
- What you can do after
- Apply it via an HTTP POST request that submits matching authorization-code parameters and authenticates the registered client.
