In REST architecture, the stateless constraint indicates that no client context should be stored on the server between requests. Each request from the client to the server must contain all the information needed to understand and process the request.

Stateless: Ensures that each request is independent and contains all necessary information.

Uniform interface: Defines a standard way of interacting with resources.

Cacheable: Responses must define whether they are cacheable to improve performance.

Client-server: Separates the client and server roles.

The error message in the cURL response indicates that the request requires a valid access token set in the Authorization request header. This error is common when the authorization header is either missing or the token provided is incorrect or expired.

-H "Authorization: Bearer YOUR_ACCESS_TOKEN"
