Start campaign postcard mailings from connected tools
When another tool signals a campaign follow-up, let Notis carry the mailing forward with the audience and postcard artwork checked first.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Send Postcard
Tool to send a postcard via u.s. mail with specified recipient, sender, and front/back images. use after confirming recipient addresses and design urls. example: send postcard(to name='john doe', ..., front image='https://...', back image='https://...')
Why this helps
Campaign mailings often stall while someone transfers a signal, checks the audience, and gathers artwork manually.
- Start a physical mailing from an existing system signal
- Keep campaign send details together
- Confirm recipient and artwork before mailing
Setup
Build it in a few focused steps.
- 1Connect Docupost once in the Notis portal.
- 2Create an automation and explain how an incoming request identifies a postcard campaign and its confirmed recipients.
- 3Pick the Notis webhook trigger.
- 4Choose where Notis should send run reports.
- 5Test with one real request and confirm the recipient addresses and front and back image URLs.

Message Status Updated
Triggers when a WhatsApp message status changes. IMPORTANT LIMITATION: WhatsApp Cloud API does not provide a native polling endpoint for message status. Status updates are ONLY delivered via webhooks in real-time. This trigger cannot directly poll the WhatsApp API for status updates. This trigger will return empty results as WhatsApp does not support this operation. To track message status updates, you must: 1. Set up a webhook endpoint to receive status notifications from WhatsApp 2. Store the webhook data in your own database 3. Use a different mechanism to query your stored webhook data For more information, see: - https://developers.facebook.com/docs/whatsapp/cloud-api/webhooks
