When I was younger (a question about exactly how much younger is outside the scope of this article), the word “token” meant fun. You see, just a couple of times a year, I would get to go to an arcade and play some amusing video games with my friends.
I would like to share a small part of my learnings from my first ever official project: POS/EDC machine integration with our billing system. This was an exciting challenge where I got hands-on experience working with APIs and vendors.
How does a Payment Machine actually work?
It's simple, start by initiating/creating a transaction, then retrieve its payment status.
Here, initiate/create refers to POST methodand Retrieve refers to GET.
