For negative reviews, a Slack alert is sent to the support team, followed by an attempt to create a support record in Supabase for tracking and follow-up.\n\n\n### Setup steps\n1. Configure the **Webhook** node and connect it to your Facebook Page review source or webhook provider.\n2. Review the **Global Configuration** node and adjust field mappings if your incoming payload structure differs.\n3. Connect your **Slack** credentials and select the channel where alerts should be delivered.\n4. Connect your **Supabase** credentials and configure the table where support records should be stored.\n5. Activate the workflow to begin monitoring Facebook Page reviews automatically.\n"
