Facebook Lead Ads to WhatsApp with GoHighLevel, Redis & Gemini

Turn Facebook Lead Ads into instant WhatsApp conversations—with GoHighLevel, Redis & Gemini

This n8n workflow automatically captures new Facebook Lead Ads submissions, upserts the lead into GoHighLevel, sends an approved WhatsApp welcome template, and stores the first message in Redis to power a Google Gemini WhatsApp sales-assistant reply with conversation context.

What this workflow does

• Captures leads from Facebook Lead Ads the moment a new submission is made.
• Normalizes & validates data (email, name, and phone). If required fields are missing/invalid, it stops processing for that lead.
• Upserts into GoHighLevel by searching for an existing contact using email; if none is found, it creates/updates the contact accordingly.
• Sends a WhatsApp welcome template to the lead and immediately saves the same initial message in Redis using a key based on the lead’s phone digits.
• Listens for incoming WhatsApp messages and ignores non-text messages.
• Generates a reply with Google Gemini, using Redis chat memory to maintain context from the lead’s earlier messages.
• Sends the Gemini-generated response back to the lead via WhatsApp.

Use cases

• Capture real-time Facebook lead form submissions and respond instantly on WhatsApp.
• Automate CRM follow-up in GoHighLevel while keeping WhatsApp conversations contextual with AI.
• Provide a lightweight sales assistant that continues the conversation using Gemini + Redis memory.

Technical details
