Authorization
Sends credentials to authenticate your request.
What it does
The Authorization header tells the server who you are. Common schemes: Bearer (tokens), Basic (username:password), and API-Key.
Bearer token
Most common for APIs:
Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...
API key (common alternatives)
Some APIs use custom headers like X-API-Key or Api-Key instead of Authorization. Check the API docs for the exact header name.
Basic auth
Username and password, base64-encoded:
Authorization: Basic dXNlcm5hbWU6cGFzc3dvcmQ=
