Facebook Graph API and more

Delphi comes with all the components you need for you to enjoy this chapter. We will basically use the TRESTClient component to do this. First, you'll be taught how to authenticate with Facebook and get an access token, and then how to run an Open Graph query to get user information. Being able to authenticate on Facebook is very useful if you are creating any kind of content application for Android or iOS.

The Graph API is the key way to interact with the Facebook platform. It is a low-level API that uses applications to query data, publish new posts, manage ads, upload photos, and more.
