Facebook Page Negative Review Watchdog → Slack Escalation + Supabase Ticket

This workflow automatically monitors Facebook Page reviews, detects negative feedback (≤ 2 stars), alerts the support team via Slack and attempts to create a support record in Supabase with built-in error handling.

This workflow listens for Facebook Page reviews through a webhook. When a review with a rating of 2 stars or less is received, the workflow prepares and standardizes the incoming data, sends an immediate Slack alert to the support team and attempts to store the review as a support record in Supabase. If the database operation fails, a fallback Slack alert is triggered with the relevant error details.

You receive:

• Instant Slack alerts for negative Facebook reviews.
• Centralized data preparation via a global configuration step.
• Automated support record creation.
• Error visibility if storage fails.
• No manual monitoring of Facebook reviews.

Ideal for customer support teams that want immediate visibility and structured tracking of negative customer feedback.

Quick Start – Implementation Steps

1. Import the provided n8n workflow JSON.
2. Configure the Facebook Page Review Trigger webhook URL in your Facebook integration.
3. Review and adjust the Global Configuration node to match your incoming payload structure.
4. Connect your Slack credentials and select the channel for alerts.
5. Connect your Supabase credentials and configure the table used for storage.
6. Activate the workflow — monitoring starts instantly.

What It Does

This workflow automates negative review handling:

1. Receives Facebook Page review data via a webhook.
2. Prepares and standardizes key review fields using a global configuration step.
3. Checks whether the review rating is ≤ 2 stars.
4. Sends a formatted Slack alert to the support team with full review context.
5. Attempts to create a support record in Supabase.
6. Detects Supabase insert failures.
7. Sends a fallback Slack alert including the Supabase error message if record creation fails.

This ensures no negative review is missed, even if downstream storage encounters issues.

Who’s It For

This workflow is ideal for:

• Customer support teams.
• Social media monitoring teams.
• SaaS companies handling public feedback.
• Operations teams needing visibility into failures.

How It Works

1. Facebook Page Review Trigger
   Receives new review data via POST webhook.

2. Global Configuration
   Maps and standardizes incoming review fields such as rating, review text, reviewer name and page name for consistent downstream usage.

   Filters reviews and allows execution only for negative ratings.

4. Slack – New Negative Review Alert
   Sends an immediate Slack notification with:

   • Page name
   • Reviewer name
   • Rating
   • Review text

5. Create Support Case (Supabase)
   Attempts to store the review as a support record.

6. Check Case Creation Failure
   Verifies whether the Supabase insert returned an error.

7. Slack – Case Creation Failed Alert
   Sends a fallback Slack alert including review context and Supabase error details.

Setup Steps

1. Import the workflow JSON into n8n.
2. Open Facebook Page Review Trigger and copy the webhook URL.
3. Configure your Facebook system to send review events to this webhook.
4. Review the Global Configuration node and update field mappings if needed.
5. Connect Slack API credentials and select the desired channel.
6. Connect Supabase credentials and configure the target table.
7. Save and activate the workflow.
