Action

Why this helps
A welcome can be delayed or forgotten when opt-in confirmation and WhatsApp follow-up happen in separate routines.
- Acknowledge an eligible signup promptly.
- Set expectations in a concise message.
- Reduce manual welcome follow-up.
Setup
Build it in a few focused steps.
- 1Connect OneSignal and Wati to Notis once in the portal.
- 2Create an automation with a plain-language prompt to send a short welcome when your service reports a confirmed WhatsApp-eligible opt-in.
- 3Select an incoming webhook as the trigger and choose a channel for run reports.
- 4Test with one real opt-in and confirm it is within an active session.
