WhatsApp AI Support Workflow with OpenAI, WooCommerce & Notion (n8n)

Instant WhatsApp AI Support—With Guardrails, WooCommerce Lookups, and Notion Knowledge

Turn inbound WhatsApp support into a fast, reliable AI experience. This n8n workflow receives messages through Whapi, screens them with OpenAI safety guardrails, answers using an OpenAI support agent backed by Notion, checks WooCommerce orders/products/customers in real time, and escalates complex issues to a human via Gmail.

What this workflow does

• Receives WhatsApp messages via a webhook endpoint you configure in Whapi.
• Extracts key message fields (sender phone, message type/text, thresholds, and an escalation email) and rejects non-text requests by replying with a “text only” message.
• Applies OpenAI guardrails to detect jailbreak attempts, NSFW content, and off-topic requests—then sends a policy-violation reply when unsafe.
• Responds with an OpenAI support agent using conversation memory keyed to the customer’s phone number.
• Answers with knowledge + live commerce data by searching policies/FAQs in Notion and fetching real-time WooCommerce information when needed.
• Escalates to a human: if the agent decides the case requires support, it emails the details to your support manager via Gmail.
• Sends the final answer back to the customer on WhatsApp using the Whapi API.

Use cases

• Answering product questions using your Notion FAQs
• Status and order-related support by looking up WooCommerce orders
• Handling customer requests while preventing unsafe or off-topic replies
• Escalating returns, billing edge cases, or complex troubleshooting through Gmail
