How WhatsApp automation works in n8n
n8n connects to WhatsApp through the official WhatsApp Business Cloud API (from Meta). You add a WhatsApp Business Cloud node to send messages and a trigger to receive them, then wire in your other tools — Shopify, your CRM, or an AI model — with no code. This is the compliant, ban-safe way to automate WhatsApp at scale.
1. Instant order and shipping updates
Trigger on a Shopify or WooCommerce order event and send a WhatsApp message with the order number and a tracking link. Customers get updates where they actually read them, and your support inbox stays quiet.
2. AI auto-reply agent
Receive an incoming WhatsApp message with the trigger, pass it to Claude, and send back an accurate answer drawn from your FAQ or order data. Add an IF guardrail so anything the AI is unsure about is handed to a human.
3. Lead capture to WhatsApp
When a new lead fills out a form (Typeform, Facebook Lead Ads), send them an instant WhatsApp welcome and notify your sales rep in the same run. Speed-to-lead wins deals.
4. Appointment and payment reminders
A Schedule Trigger checks tomorrow's bookings in Google Calendar or Calendly and sends a WhatsApp reminder, cutting no-shows. The same pattern works for unpaid invoices from Stripe.

What you'll need
A Meta WhatsApp Business account and a verified number, then the WhatsApp Business Cloud credential in n8n. Templates for the first outbound message must be pre-approved by Meta — n8n sends them once approved. Explore WhatsApp recipes to start from a working workflow.

Will automating WhatsApp get my number banned?
Not if you use the official WhatsApp Business Cloud API, which n8n supports. Bans happen when people use unofficial libraries that scrape the consumer app. Stick to the official API and approved message templates and you're compliant.
Do I have to pay for WhatsApp messages?
Meta charges per conversation (rates vary by country), separate from n8n. Service and utility messages like order updates are inexpensive; there's also a free tier of service conversations each month.
Can the AI agent reply in the customer's language?
Yes. Claude detects and replies in the incoming language automatically, so a single WhatsApp agent can handle a multilingual audience without extra setup.
