How to learn how to work with REST API?

If you don't know how to work with the REST API, I recommend you check out the Netlas API guide I wrote for Netlas.io.

Netlas Cookbook

There it is very brief and accessible to write how to automate requests in different programming languages (focus on Python and Bash) and process the resulting JSON data.
