Send Facebook Group Posts to Your Webhook

With the Groups Watcher Pro plan, you can send every new post from your monitored Facebook groups and pages to your own webhook URL. We POST a simple, flat JSON payload to your endpoint so you can pipe posts into your CRM, Slack, Discord, Airtable, or any custom app.

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

Test your webhook

Before or after configuring your endpoint, you can send a test payload to make sure your URL is correct and your server responds. Enter your webhook URL and we’ll POST a sample payload (same shape as the real one) so you can verify everything works.

Request

Method: POST
Headers: Content-Type: application/json
Body: JSON with message and data (see below)

Example: n8n (Slack, Email, SMS, Discord)

You can use the webhook payload in n8n in several ways: post to Slack, send an email, send an SMS via Twilio, and post to Discord. Build a workflow with a Webhook trigger, then add the branches you need. Save the workflow in n8n before testing the webhook URL.
