Send Shopify order confirmations via WhatsApp using MoltFlow

Description

What this template does

Sends instant WhatsApp order confirmation messages to customers when they place an order on your Shopify store, powered by MoltFlow (https://molt.waiflow.app).

How it works

Shopify webhook fires on new order creation
Parse order data — extracts customer name, phone, order number, items, and total
Check phone — skips orders without a phone number
Send WhatsApp confirmation — delivers a personalized message via MoltFlow API
Log result — records success or skip for tracking

Set up steps

Create a MoltFlow account (https://molt.waiflow.app) and connect your WhatsApp number
Generate an API key in MoltFlow (Sessions page, API Keys tab)
Activate this workflow in n8n and copy the webhook URL
In Shopify Admin, go to Settings, Notifications, Webhooks and add the n8n URL for Order creation
Set YOUR_SESSION_ID in the Format Order Message code node
Add your MoltFlow API key as an HTTP Header Auth credential (Header Name: X-API-Key)
