How to send order status SMS from Webflow e-commerce with Twilio and one route handler
Blog post from Webflow
Webflow E-commerce stores can send order confirmation and status-update SMS messages through a Webflow Cloud Next.js Route Handler and Twilio’s Messages API without third-party automation platforms. The integration requires a Webflow E-commerce site, Cloud project, Twilio SMS-capable number and API credentials, site token, and a checkout Additional Info field to collect phone numbers, since standard Webflow order data includes only names and emails. The handler preserves the raw webhook body, validates Webflow’s HMAC signature and timestamp to prevent spoofing and replay attacks, extracts order details and phone data, and uses `fetch` with Twilio API-key authentication to send targeted messages for new, fulfilled, refunded, or disputed orders. Webhooks for new orders and changed orders should be registered through Webflow’s API because each receives a distinct signing secret and API-created webhooks include the validation signature header. The guidance also covers testing with real or zero-total orders, local exposure through ngrok, Twilio and Webflow logs, and common problems such as Workers-runtime incompatibilities with the Twilio Node SDK, incorrect webhook secrets or premature body parsing, and absent phone fields, including on PayPal checkout pages.
