Authorization

Credentials for authenticating the request

What the Authorization header does

Authorization carries the credentials that authenticate a request — most commonly Bearer <token> for API tokens/JWTs, or Basic <base64> for basic auth. Always send it over HTTPS, since anyone who sees the header can reuse the credentials.

Example

Authorization: Bearer <token>

Where it's used

Authorization is a request header. Request headers are sent by the client to describe the request and what the client can accept.
