To create an API User, you need the following things in place: X-Reference-Id and Ocp-Apim-Subscription-Key

1. X-Reference-Id


This is used as User ID since the Sandbox is a Mock Environment so we kinda create our own ids and send them over
to the sandbox so it can uniquely identify the user
Get the value for this here: https://www.uuidgenerator.net/api/version4
Remember to keep this safely as we will use it when configuring our POST request
Lets say you have your X-Reference-Id as: 9f92971b-cd2e-4feb-9053-0b14d53ac4f5

2. Ocp-Apim-Subscription-Key


Get this from the Primary or Secondary Key of your Collections | Enable remote collection of bills, fees or taxes subscription.
