Automate WooCommerce Customer Support with Gemini & GPT via Telegram & Gmail

Description

🤖 AI Support Bot for WooCommerce with Gemini & GPT (Telegram & Gmail)

Managing customer support across multiple platforms like email and chat can be a huge time sink. Answering the same questions about order status repeatedly takes your focus away from growing your business. This workflow solves that problem by deploying a 24/7 conversational AI agent to act as your first line of support for your WooCommerce store.

This AI-powered bot can handle customer inquiries from both Telegram and Gmail, understand conversational follow-ups, and use a tool to fetch live order data directly from your WooCommerce store. It's designed to be reliable, with a primary/fallback AI model setup, and robust enough to prevent the common pitfalls of email automation like infinite reply loops.

How It Works ⚙️
The workflow operates in a clear, logical sequence:

📢 Multi-Channel Ingestion: The workflow starts when it receives a message from one of two sources:

Telegram: An instant webhook trigger fires for every new message.
Gmail: A polling trigger checks your inbox every minute for new, unread emails.

💎 Data Normalization: All incoming requests are merged and processed by a Set node. This crucial step transforms the platform-specific data into a universal format that the rest of the workflow can understand (e.g., platform, sender_id, query_text).


🧠 AI Processing: The standardized query is sent to a LangChain Agent. This agent is the "brain" of the operation. It uses Conversational Memory to understand the context of the conversation (like when a user provides an order ID in a follow-up message).

🛠️ Tool Usage: Based on its prompt, the AI Agent determines if it has enough information to use its one available tool: Get an order in WooCommerce. If a valid Order ID is present, it calls the tool to fetch live order details.

📮 Response & Routing: The agent formulates a natural language response. A Switch node then inspects the platform field and routes the response to the correct channel.

✅ Cleanup: For the Gmail path, two final actions occur in parallel: the reply is sent, and the original incoming email is marked as 'Read'. This is a critical step to prevent the workflow from re-triggering on the same email in an infinite loop.

Nodes Used 🔗

This workflow uses a combination of standard nodes and AI nodes to achieve its goal:

Telegram Trigger: To receive messages from Telegram in real-time.
Gmail Trigger: To poll for new unread emails.
Merge: To combine inputs from multiple triggers.
Set: To normalize data into a consistent format.
LangChain Agent: The core AI "brain" that orchestrates the logic, memory, and tools.
Google Gemini & OpenAI: Used as the primary and fallback language models for the agent.
WooCommerce Tool: The tool the AI agent uses to fetch order data.
Switch: To route the final reply to the correct platform.
Telegram: To send the final response to Telegram.
Gmail: To reply to emails and mark them as read.
