Postman is a developer tool which make it easy to invoke REST API resources and receive their responses. We created a set of Postman collection that you can download and import into the program. You can set it up in the following steps.
First of all, download and install Postman.
From any API request, on the Authorization tab,
Set the Postman environment; create a key as access_token and copy the obtained access_token to the value. When you set your access_token in Postman environment properties, remember to select the environment you have created, then you can start sending API calls.
To make things as easy as possible, we have created platform-specific code snippets that you can use in your development environment to get up and running quickly.
