Curl POST With Basic Authentication

An example of making a POST request with Basic Authentication credentials using Curl. Basic Authentication credentials are passed to Curl with the --user "login: password" command-line option. The user's credentials are automatically converted by Curl to a Base64 encoded string and passed to the server with an Authorization: Basic [token] header. POST data is passed to Curl with the -d option. In this Curl POST with Basic Authentication header example, we sent a request to the ReqBin echo URL. Click Run to execute the Curl POST request online and see the result.
