Here is a brief explanation of the different status codes 

– 401: Unauthorized – The request requires user authentication.
– 402: Payment Required – This status code is reserved for future use.
– 403: Forbidden – The server understood the request but refuses to authorize it.

Here’s a brief explanation of the different status codes:

– 501: Not Implemented – The server either does not recognize the request method, or it lacks the ability to fulfill the request.
– 502: Bad Gateway – The server received an invalid response from the upstream server while trying to fulfill the request.
– 504: Gateway Timeout – The server, while acting as a gateway or proxy, did not receive a timely response from the upstream server.

– POST: Send data to a server to create a resource.
– PUT: Update or create a resource on the server with the provided data.
– DELETE: Remove a resource from the server.
– OPTIONS: Describe the communication options for the target resource.

409: Conflict – Indicates that the request could not be completed due to a conflict with the current state of the resource, such as a version control conflict.

17) 3) The resource requested has been found and moved temporarily to new URL location.
