I’ve been trying to get into working with how to use APIs in programming, which can be really useful with any solution that uses REST APIs (such as vSphere, Cisco ACI, and a myriad of others). There are several commands to be used, but there are four basic commands that will get you started. These commands fulfill the CRUD (Create, Read, Update, Delete) criteria. They are: Put, Get, Post, and Delete.
By using a REST client such as POSTMAN, which is a Google Chrome extension, we can use these commands to manipulate the technology. POST will CREATE something, GET will READ it, PUT will update it, and DELETE will of course DELETE it.
