Pair an approved WhatsApp template with a letter follow-up
A template review update can be the cue to complete a related physical mailing. Keep recipient and PDF checks in place before Docupost sends.
Trigger
Message Template Status Update
Triggered when the review status of a WhatsApp message template changes — for example approved, rejected, or flagged — on your WhatsApp Business Account.
Action
Send Letter
Tool to send a letter via u.s. mail with specified recipient, sender, and pdf. use after confirming recipient and document details. example: send letter(to name='john doe', to address='123 main st, ...', file url='https://...')
Why this helps
A newly approved communication can still leave a physical follow-up waiting in a separate workflow.
- Turn a template status update into a clear mailing next step
- Keep related physical communication in view
- Confirm recipients and document details before sending
Setup
Build it in a few focused steps.
- 1Connect WhatsApp and Docupost once in the Notis portal.
- 2Create an automation and state which template status change should prompt a letter and what recipient and PDF details to confirm.
- 3Pick the WhatsApp Message Template Status Update trigger.
- 4Choose where Notis should send run reports.
- 5Test with one real template status event and confirm the recipient and PDF URL.
Questions about this workflow
Does this trigger mean the template was approved?
It fires when the review status changes, such as approved, rejected, or flagged. Tell Notis which status should prompt a letter.
Does template approval provide mailing addresses?
No. The Docupost send requires a recipient address and a PDF URL, so those details must be available and confirmed.
Can I use this for a letter campaign?
Yes, when the campaign's recipients and letter document are known. Describe the intended follow-up in the automation prompt.

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
