To utilize the Facebook API, similar to the Login with Facebook or Facebook Graph API, you have to make a Facebook app. At the point when you make a Facebook app, that application will have an App ID and an App Secret. You need these credentials to do nearly anything with Facebook, including experiencing the OAuth authorization flow and working with Facebook's Graph API.
With the App ID, you can send API requests to Facebook for information. The Facebook app secret can be utilized to decode the encrypted data.
A Facebook App ID is a unique number that distinguishes your application when you demand promotions from Audience Network.
Each application on Audience Network must have a unique Facebook App ID. You may as of now have an App ID if your application utilizes Facebook Login or Facebook Analytics for Apps.
