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 at a time with message and data (group name, post URL, body, images, videos, and more). If your webhook is set to receive all posts, we send a batched body with a posts array. See Batched payload (all posts).

Test your Zapier webhook

Before or after configuring your Zap, you can send a test to your Zapier catch hook URL to make sure it receives data. Open Send test webhook and choose default (keywords / AI validation) or all posts so the sample matches your campaign. Enter the URL and we send the matching sample so you can verify the Zap trigger fires.

Request

• Method: POST
• Headers: Content-Type: application/json
• Body: Structured data with either message + data (one post), or message + posts + a top level timestamp when your Groups Watcher webhook is set to receive all posts (see Batched payload). 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.

Depending on your campaign, Groups Watcher sends one of two layouts of structured data. Default means one post per request with message and data (posts that pass keywords or AI validation). All posts means a batched body with message, a posts array, and a top level timestamp. See Single post and Batched payload below, or the full write-up on Custom webhook.

Single post per request (default)

Each POST has a short message and a data object with all post fields.

{
  "message": "<string>",
  "data": {
    "group_name": "<string>",
    "group_id": "<string>",
    "poster_name": "<string>",
    "poster_url": "<string>",
    "post_url": "<string>",
    "group_url": "<string>",
    "post_id": "<string>",
    "post_type": "regular_post" | "marketplace",
    "body": "<string>",
    "images": ["<url>", ...],
    "videos": ["<url>", ...],
    "timestamp": "<ISO 8601 string>"
  }
}

Batched payload (all posts)

When your custom webhook is set to receive all posts, we send one POST per batch. The message summarizes the count (for example 1 new post in your groups or 3 new posts in your groups). Each element of posts uses the same field names as data above, as a flat object inside the array. The top level timestamp is when we sent the webhook.

{
  "message": "2 new posts in your groups",
  "posts": [
    {
      "group_name": "<string>",
      "group_id": "<string>",
      "group_url": "<string>",
      "poster_name": "<string>",
      "poster_url": "<string>",
      "post_url": "<string>",
      "post_id": "<string>",
      "post_type": "regular_post" | "marketplace",
      "body": "<string>",
      "images": ["<url>", ...],
      "videos": ["<url>", ...],
      "timestamp": "<ISO 8601 string>"
    },
    {
      "group_name": "<string>",
      "group_id": "<string>",
      "group_url": "<string>",
      "poster_name": "<string>",
      "poster_url": "<string>",
      "post_url": "<string>",
      "post_id": "<string>",
      "post_type": "regular_post" | "marketplace",
      "body": "<string>",
      "images": ["<url>", ...],
      "videos": ["<url>", ...],
      "timestamp": "<ISO 8601 string>"
    }
  ],
  "timestamp": "<ISO 8601 string>"
}

Slack, Discord, ntfy, and Teams use different formats. The examples above apply when your automation receives a webhook URL from Groups Watcher (including via Zapier, Make, or n8n).

The field reference table below describes data.* for the default format. For batched all posts, each element of posts uses the same keys as data (flat objects in the array).

Field reference

Example payload

This is what Zapier receives for each new post. Use these fields in your Zap actions (e.g. add row to Google Sheets, send Slack message, create CRM lead).

    "group_name": "Tampa Bay Homeowners",
