Make new subscriber contact setup one less manual step
Let your signup service notify Notis when a subscriber is ready, then create the corresponding Wati contact for a smoother follow-up path.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Add Contact
Tool to add a new contact in wati. use when registering a customer's whatsapp number before sending messages.
Why this helps
Manually adding each new subscriber to a separate WhatsApp contact list creates busywork and invites missed handoffs.
- Register eligible contacts as signups are confirmed.
- Reduce repetitive contact entry.
- Prepare the contact record for a later conversation.
Setup
Build it in a few focused steps.
- 1Connect OneSignal and Wati to Notis once in the portal.
- 2Create an automation in the portal with a plain-language prompt to add a Wati contact when your signup service reports a new subscriber with a WhatsApp number.
- 3Select an incoming webhook as the trigger and choose a channel for run reports.
- 4Test with one real eligible signup and confirm that the contact was added.
Questions about this workflow
Does OneSignal provide a trigger event here?
No. Your signup service sends the webhook to Notis, which then uses the connected tools as described in the prompt.
Should every subscriber be added?
Only describe adding contacts who are eligible and have a usable WhatsApp number in the data your service sends.
