Using Postman to test REST API

Hi all ,

I am a newbie to REST API.

I found so many documents from Oracle for the EPM API.

However, I don't know how to use it for my testing.

Currently, some friends tell me that I can use Postman for testing API.

It sounds interesting to me (non-tech person).

And I log in to Postman, based on Oracle's guidance.

Is there anybody using Postman for testing REST API?

Or which software are you using for testing?

Hope to hear about your experience.

Thanks!
