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.
