Authentication · Request header
Authorization
Credentials for authenticating the request.
What is Authorization?
Authorization carries the credentials the server uses to identify the caller — typically a Bearer token, Basic base64(user:pass), or a signed AWS Signature.
Typical usage
Sent by clients on requests that require authentication.
Examples
OAuth 2.0 / JWT
Authorization: Bearer eyJhbGciOiJIUzI1NiI...HTTP Basic
Authorization: Basic dXNlcjpwYXNzCommon gotchas
Basic authentication is only Base64 encoded — never a substitute for TLS. Always require HTTPS when accepting Authorization.
