Postman - PUT Requests


Advertisements

A Postman PUT request is used to pass data to the server for creation or modification of a resource. The difference between POST and PUT is that POST request is not idempotent.

This means invoking the same PUT request numerous times will always yield the same output. But invoking the same POST request numerous times will create the similar resource more than one time.

Before creating a PUT request, we shall first send a GET request to the server on an endpoint − http://dummy.restapiexample.com/api/v1/employees. The details on how to create a GET request is explained in detail in the Chapter – Postman GET Requests.

On applying the GET method, the Response body obtained is as follows −
