Working with APIs Using JWT (JSON Web Tokens)
Explains the structure of a JSON Web Token (header, payload, and signature) and how the login-then-bearer-token flow works between a client and a protected API. Shows how to create tokens with PyJWT including an expiration claim, verify and decode them with proper error handling for expired and invalid tokens, and attach them to API requests via the Authorization header. Covers refresh tokens for silent session renewal and closes with four security best practices: HTTPS, short-lived tokens, HTTP-only cookie storage, and token blacklisting.
