400The server cannot or will not process the request due to something that is perceived to be a client error (e.g., malformed request syntax, invalid request message framing, or deceptive request routing).

403The client does not have access rights to the content; that is, it is unauthorized, so the server is refusing to give the requested resource. Unlike 401
Unauthorized, the client's identity is known to the server.

500The server has encountered a situation it does not know how to handle.
