To make a POST request to an API endpoint, you need to send an HTTP POST request to the server and specify a Content-Type request header that specifies the data media type in the body of the POST request. The Content-Length header indicates the size of the data in the body of the POST request. In this Sample API POST example, we send a POST API request to the ReqBin echo URL.

The primary purpose of APIs is to hide the internal details of how the system works and show only those parts that are visible and accessible to external systems, keeping them consistent even if the internal implementation change later.
