What does a 403 Forbidden error mean in Postman PUT request?

A 403 Forbidden error in a Postman PUT request indicates that the server understands the request but refuses to authorize it. This usually means the client (Postman) doesn't have the necessary permissions to perform the action. It's not an error on the client's part; it's a permissions issue on the server. Common causes include insufficient user privileges, incorrect authentication, or a firewall blocking the request.
