Hackbot adds features to Facebook Groups through automation.
An instance of Hackbot is running on Hackathon Hackers.
1. Install Hackbot
$ npm install -g hackbot
2. Get your long-lived Facebook access token
Note: This process is annoying. Please consider implementing this through a web-based OAuth flow.
You'll need to set a few configuration options before using Hackbot: your Facebook Group ID, the refresh rate in milliseconds (5s is a good number), and the IDs of the group's moderators to the configuration file.
To generate an access token, open up the Facebook Graph API Explorer and make sure you're using a custom application. Click "Get Access Token" and make sure the
publish_actions permissions are ticked.
Click the blue "Get Access Token" in the modal. Copy the short-lived access token and navigate in your browser to the following URL:
https://graph.facebook.com/oauth/access_token? client_id=APP_ID& client_secret=APP_SECRET& grant_type=fb_exchange_token& fb_exchange_token=SHORT_LIVED_ACCESS_TOKEN
SHORT_LIVED_ACCESS_TOKEN with the proper values. Take the long-lived (60 day) access token in the body and save it somewhere for safe-keeping. You'll need it when you run Hackbot below.
3. Collect the Graph IDs of your group's moderators
You can use the Graph API Explorer to find the numeric Graph API IDs of your group's moderators.
Keep in mind that Facebook's user IDs are unique to each application, so you'll have to get creative. Try digging through your friends list at
There will be much better usage documentation coming soon, but here's how it works:
$ hackbot GROUP_ID ACCESS_TOKEN -m MOD_ID1,MOD_ID2,MOD_ID3 -s close,delete --interval 5
$ git clone email@example.com:kern/hackbot.git $ npm install $ npm run dev -- [see usage above]
Lint before committing:
$ npm run lint
