Understanding HTTP Status Codes

When you send an API request to the server, the server returns a response along with the status codes. The status code helps you understand whether the request was successful or any error occurred.

The following are the most commonly used HTTP Status Codes along with their descriptions:

Status Code	Result	Description
200 OK	Success	The request was successful, and the server returned the expected response.
201 Created	Resource Created	The request was successful, and a new resource was created on the server.
204 No Content	Success (No Data)	The request was successful, but the server did not return any content.
