Enable smart, real-time answers in your WhatsApp groups using a custom webhook, Pinecone vector database, and no Facebook Business setup.

🟡 Note: This template uses a custom WhatsApp webhook. It does not use the official WhatsApp Business API.


👥 Who is this for?

This workflow is designed for individuals and teams who want to enable smart WhatsApp group automation — without going through Meta’s official WhatsApp Business API. Ideal for small businesses, internal teams, communities, and personal power users.


❓ What problem is this solving?

Setting up WhatsApp bots with intelligent responses often requires approval from Meta and a verified business account. This workflow removes those barriers by using a self-hosted webhook to handle incoming messages and respond using a document-trained AI via Pinecone.


⚙️ What this workflow does

  • Connects a regular WhatsApp number to a custom webhook
  • Adds the bot to any group chat (it stays silent unless mentioned)
  • Indexes documents from Google Drive into Pinecone
  • Responds with intelligent, context-aware answers from your custom knowledge base
  • Auto-updates its knowledge every minute as the document changes

🛠️ Setup

Step 1: Connect Google Drive

Step 2: Configure Pinecone

  1. Create an index in Pinecone
    • Dimension: 1536
  2. Select this index in both Pinecone nodes
  3. Click Test Workflow to ingest your document into Pinecone

Step 3: Get Access to the WhatsApp Webhook

Step 4: Test WhatsApp Integration

  • One-on-one test: Send a message from another number
  • 👥 Group test: Add the bot to a group; it will only respond when tagged

🧩 How to customize this workflow

  • Modify the system prompt inside the AI agent node to control tone and behavior
  • Update the connected Google Doc to match your specific domain (e.g. FAQs, SOPs, product manuals)
  • Adjust the Pinecone sync frequency if you want updates more or less often

📚 Use cases

  • Customer Support: Instant, intelligent replies in WhatsApp without live agents
  • Team Knowledge Bot: Tag the bot for quick access to SOPs and internal docs
  • Community Groups: Automate common questions while keeping noise low
  • Personal AI Assistant: A WhatsApp chatbot trained on your notes and files
