CURL is a tool to transfer data from or to a server, using different types of protocol protocols.

Curl POST JSON with string request
Command :
Post example with string object as request body
curl -X POST "your-post-url" -H "accept: text/plain" -H "Content-Type: application/json" -d "\"your string request data\""
In the above command,
-X —-> The HTTP verb indicating operation is GET, POST, PUT or DELETE, etc
–d or --data —-> the data you want to send.
Example 1

CURL POST JSON using Basic Authentication
