Facebook Page Negative Review Watchdog → Slack Escalation + Supabase Ticket
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 Import the provided n8n workflow JSON. Configure the Facebook Page Review Trigger webhook URL in your Facebook integration. Review and adjust the Global Configuration node to match your incoming payload structure. Connect your Slack credentials and select the channel for alerts. Connect your Supabase credentials and configure the table used for storage. Activate the workflow — monitoring starts instantly.
