general

Quick start

What it does. Text messages to customers for order updates, one-time codes and promotions, sent to the phone number on their account or guest order. Choose Twilio, MSG91 or Vonage and manage the messages and which events send them.

Who can use it

  • Off until you switch it on.
  • Your plan decides whether you can use it. The module card in Settings → Modules shows Not in your plan (with See plans) or Paid add-on (with Buy add-on) when it is not included. The features list shows which plans include it.

Switch it on

  1. In your admin, open Settings → Modules.
  2. Find SMS Notifications. If it is on the Installed tab, click Enable; if not, open the Browse tab and click Install.
  3. Click Configure, fill in Provider, and save.

Switching it off later stops it working but keeps its data, so switching it back on picks up where you left off.
