Qualify Facebook Leads via ElevenLabs Voice Calls (n8n + Supabase + Slack)

Auto-qualify Facebook Lead Ads with ElevenLabs AI phone calls—then notify your team in Slack

This n8n workflow captures new Facebook Lead Ads submissions, saves them to Supabase, and—during your calling hours—kicks off an ElevenLabs conversational outbound voice call to qualify leads automatically. When the call ends, it updates the lead record and alerts your team via Slack (with detailed Gmail follow-up for booked/qualified outcomes).

What this workflow does

• Triggers on new Facebook Lead Ads form submissions.
• Normalizes lead fields and checks Supabase for an existing record using the Facebook lead ID to skip duplicates.
• Inserts the new lead into your Supabase leads table.
• Checks business hours against your configured calling window.
• If within calling hours, it sends an HTTP request to ElevenLabs to start an outbound AI phone call, then updates Supabase with the conversation/call ID and call status (or logs failures and alerts Slack).
• If outside calling hours, it marks the lead as queued for manual callback and posts an after-hours notification to Slack.
• Receives an ElevenLabs post-call webhook, extracts the transcript, summary, qualification, and booking signals, and updates the matching Supabase lead by call ID.
• Routes results as booked, qualified (no booking), or other—then sends tailored Slack messages and a detailed Gmail email for booked and qualified leads.

Use cases

• Speed-to-lead qualification for Facebook Lead Ads campaigns with no manual dialing during business hours.
• After-hours lead capture that’s automatically queued for a manual callback team process.
• Lead scoring and follow-up using ElevenLabs transcripts and booking signals, stored in Supabase.
