Send Facebook Group Posts to Zapier

With the Groups Watcher Pro plan, you can send every new post from your monitored Facebook groups and pages to Zapier. Use Webhooks by Zapier to get a catch hook URL, add it in Groups Watcher, and we deliver post details you can wire into Google Sheets, Slack, email, CRM, or 6,000+ apps. Most alerts arrive in under 60 seconds.

This feature is available on the Pro plan. Check pricing here.

Set up Zapier

1. In Zapier, create a new Zap. Choose Webhooks by Zapier as the trigger.
2. Select Catch Hook and continue. Zapier will give you a unique URL.
3. Copy that URL and paste it into Groups Watcher as your webhook URL (in your campaign or Pro plan setup).
4. When you are ready to test, trigger a post from Groups Watcher (or use the test tool below); Zapier will receive the data and you can map fields in your Zap.

The information we send matches our custom webhook doc: one alert per request with message and data (group name, post URL, body, images, videos, and more).

Test your Zapier webhook

Before or after configuring your Zap, send a test to your Zapier catch hook URL. Open Send test webhook, enter the URL, and we send a sample POST so you can verify the Zap trigger fires.

Request

• Method: POST
• Headers: Content-Type: application/json
• Body: JSON with message and a data object (one post per request). Full reference: Custom webhook.

Payload (Zapier trigger data)

For the default format, the body has a short message (summary line) and a data object with all post fields. In Zapier map data.group_name, data.post_url, data.body, and so on in your Zap steps.

Each POST includes a short message and a data object with all post fields. See the full write-up on Custom webhook.

Payload shape

  "message": "<string>",
  "data": {
    "group_name": "<string>",
