Who Is This For?

This n8n automation workflow is designed for customer support teams, business owners, or service providers who want to automate customer interactions on WhatsApp.

If you regularly receive customer queries about your products, services, or technical issues — and need a system that can instantly respond, fetch data from Google Sheets or Docs, log support tickets, and send human-like replies — this workflow is for you. It’s perfect for teams using Rapiwa, Google Sheets, and Google Docs who want to provide a smart, AI-driven, yet personal support experience.

What This Workflow Does

This workflow is structured around a single intelligent AI assistant called Rapiwa that interacts with customers in real time through WhatsApp.

Key Features

AI-Driven Support Assistant (Rapiwa)
WhatsApp Integration via Rapiwa API
Dynamic Data Access (Google Sheets + Docs)
Knowledge Base Search
Conversation Memory
Automatic Logging
Multi-Product Support

Workflow Overview

  1. Rapiwa Trigger (Start Node)

    • Starts the workflow automatically whenever a new WhatsApp message is received in your Rapiwa account.
    • Example: When a customer sends a message like “What’s the price of SocialVibe?” or “I can’t access my dashboard”, this node triggers the workflow.
  2. If (Check Text)

    • Detects if the incoming message contains text (not just images, videos, or audio).
    • If it’s text, the workflow continues; otherwise, it stops or handles it differently.
  3. AI Agent – Customer Support Agent

    • This is the brain of the system — your AI Assistant (Rapiwa).
    • Interprets the user’s question, retrieves information, and replies in a clear, WhatsApp-friendly format.
    • Reads product details and company info from Google Sheets/Docs.
    • Fetches documentation links from the connected “Support Desk” and product-specific HTTP tools.
    • Logs customer issues to the support sheet for tracking and analysis.
  4. Memory (Session Context)

    • Stores chat history per user session so Rapiwa remembers context during a conversation.
  5. Research (AI Support Tool)

    • Acts as Rapiwa’s research assistant — gathers and organizes information from multiple sources.
    • Sources: Google Sheets, Google Docs, HTTP Tools, and Support Desk.
  6. Replay (Rapiwa Send Message)

    • Sends the AI’s final message back to the customer on WhatsApp using the Rapiwa API.
    • WhatsApp-optimized plain text messages only.

Data & Integrations

🔹 Google Sheets (Database)

  • Product Data Sheet: Holds product names, descriptions, and pricing.
  • Service Data Sheet: Lists offered services with details.
  • Support Log Sheet: Records each issue (Issue, Category, Solution).

🔹 Google Docs

  • Provides company information when a user asks about your organization.

Example Use Case

User Message:
> “Hi, I’m having a problem with my Faculty login.”

Rapiwa’s AI Response:
> “I’m sorry you’re having trouble logging in to Faculty. Please try resetting your password here: https://faculty.spagreen.net/docs/#reset-password
> If the issue continues, I can log this for support. Would you like me to do that?”
