Postman is a popular web development and testing tool for working with APIs and can be downloaded from https://www.getpostman.com/
It provides easy access to the APIs to perform merge operations using your licensed products.
Postman provides extensive features for performing integration testing with our API. It allows for repeatable, reliable tests that can be automated and used in a variety of environments and includes useful tools for persisting data. See the Postman Learning Centre.
