Status Codes

Every valid HTTP request receives a response that is comprised of three main components:

• A 3-digit response status code that gives information about the success or failure of the request, the returned content, and other information specific to the request.

(2) The response header(s), which vary by request. These headers contain metadata information about the request, the response, the response data, and/or attributes of the server.

(3) The response body where free-form text information can be returned to the requester in either JSON (default) or XML format and in a standard defined by the application. This is where application-specific data pertaining to representation, success, and errors is returned to the requester.

Comprehensive list of HTTP status codes: https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html

Lgfapi uses many of the available HTTP response status codes to convey success or failure of the request back to the user. All response status codes fall into 1 of 4 categories:

1xx – Informational

2xx – Success

3xx – Redirection

4xx – Failure
