Examining the Short-Lived Access Token

The next step in the flow: the access token

In the last lesson, we walked through the Facebook authorization flow. Just before that, we had set up our “Login with Facebook” button, which is the starting point for your users in going through the flow. At the time, you clicked on the “Login with Facebook” button, and you logged in with your Facebook credentials and saw some JSON data output to the screen, with an accessToken included in it.

Now that we have walked through the authorization flow, you see why getting that accessToken is an important step for moving along in this flow.
