Facebook GraphAPI

This shows a simple use-case of Facebook's GraphAPI. The API is free to use except with a rate-limit, find out more: https://developers.facebook.com/docs/graph-api/overview/rate-limiting#platform-rate-limits

Setup

Register a developer account with Facebook and creating a meta app

• Begin the process by visiting this link: https://developers.facebook.com/docs/development/register/
• Next, register a meta application, this is to get the access token

Install dependencies

pip install -r requirements.txt

Usage

Obtain a long-lived access token

• A long-lived access token last for 60 days, so you can test your applications without the need to regenerate the access token, more info: https://developers.facebook.com/docs/facebook-login/guides/access-tokens/get-long-lived/

https://graph.facebook.com/v16.0/oauth/access_token?grant_type=fb_exchange_token&client_id=${CLIENT ID}&client_secret=${CLIENT SECRET}&fb_exchange_token=${PAGE/USER ACCESS TOKEN}

Using the API

• You can use the built-in api explorer: https://developers.facebook.com/tools/explorer/ or in my case I prefer the usage of Postman
• You need to acquire the page-id of your Facebook's page, which could be obtained from the page's url
• You can begin usage of the API now with:

https://graph.facebook.com/${PAGE ID}/posts?access_token=${ACCESS TOKEN}

Using app.py

• Create a file secret.py or .env and store your credentials, in app.py import the credentials to be used
• Retrieve:
  • Parent post content
  • Child comments' content
  • Child comments' author
  • Reactions
  • Dates
  • Hyperlinks
  • Most reacted comments
