This workflow automates customer support across multiple channels (Email, Live Chat, WhatsApp, Slack, Discord) using AI-powered responses enhanced with Retrieval Augmented Generation (RAG) and your product documentation. It intelligently handles incoming queries, provides instant and context-aware answers, and escalates complex or negative-sentiment cases to your human support team. All interactions are logged and categorized for easy tracking and reporting.


Key Features

  • Omnichannel Support: Handles customer queries from Email, Live Chat, WhatsApp, Slack, and Discord.
  • AI-Powered Answers: Uses RAG to generate accurate, context-aware responses based on your product documentation.
  • Automatic Escalation: Detects low-confidence or negative-sentiment cases and escalates them to your human support team.
  • Conversation Logging: Automatically logs and categorizes all conversations for future analysis.
  • Weekly Reporting: Sends automated weekly summaries and metrics to your support team.

How It Works

  1. Trigger: The workflow starts when a new message is received on any supported channel.
  2. Normalization: Incoming messages are normalized into a common format for unified processing.
  3. Context Management: Conversation history is fetched and merged with the new query for better AI context.
  4. AI Response: The workflow uses RAG to generate a response, referencing your product documentation.
  5. Confidence & Sentiment Analysis: The response is scored for confidence and sentiment.
  6. Escalation Logic: If the response is low-confidence or negative, the workflow escalates the case to your support team and creates a ticket.
  7. Response Delivery: The answer (or escalation notice) is sent back to the customer on the original channel.
  8. Logging & Reporting: All interactions are logged, categorized, and included in weekly reports.

Configuration

  1. Connect Your Channels: Set up triggers for each channel you want to support (Email, Webhook, WhatsApp, Slack, Discord).
  2. Add Your Documentation: Integrate your product documentation source (e.g., Google Docs, Notion, or a knowledge base) for the RAG model.
  3. Configure AI Model: Set your preferred AI provider and model (e.g., OpenAI, Azure OpenAI, etc.).
  4. Set Escalation Rules: Adjust confidence thresholds and escalation logic to fit your support workflow.
  5. Integrate Support Tools: Connect your ticketing system (e.g., Zendesk) and reporting tools (e.g., Google Sheets, Slack).
  6. Test the Workflow: Send test queries from each channel to ensure correct routing, AI responses, and escalation.

Notes
