When it comes to API development, my weapon of choice for testing my code is Postman. I start using Postman since it's still a Chrome App. Now it encourages its user to use Postman Native app. I definitely love the idea, but all I can find is a download link without any installation document for Linux Mint.
So, here's what I did:
Download postman
$ wget https://dl.pstmn.io/download/latest/linux64 -O postman.tar.gz
Extract archive
$ sudo tar -xzf postman.tar.gz -C /opt
