PlayFab - Understanding the REST API Architecture

REST API Reference - PlayFab

Fetching and storing data in PlayFab is implemented via REST APIs.

If you have web development experience, this will immediately click.

PlayFab sends a "Request" object to the web server and receives a "Response" object back.

It's actually pretty straightforward, but it can be hard to explain to someone who hasn't seen it before.

If the above doesn't make sense yet, studying web servers will be extremely helpful.

If it does make sense, just think of PlayFab as a web server and use it accordingly.
