Move approved overdue invoice notices to the mail
Turn an approved next step into a physical notice with recipient and document details checked first.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Send Letter
Submits a letter for paid printing and postal delivery; the mailing cannot be undone.
Why this helps
Following up on overdue invoices can stall when the decision to mail has been made but the address, PDF, and mailing task still need manual coordination.
- Start the mailing from an existing receivables process.
- Keep recipient and document checks with the send instruction.
- Reduce the manual handoff between approval and postal delivery.
Setup
Build it in a few focused steps.
- 1Connect Ai ml api and Docupost once in the Notis portal.
- 2Create an automation for approved overdue invoice notices.
- 3Tell Notis to send the supplied notice PDF only after the recipient and document details are confirmed.
- 4Choose the webhook trigger and a report channel.
- 5Test with one real notice that is approved to mail.
Questions about this workflow
Does this decide which invoices are overdue?
No. The webhook request should come from a process that has identified and approved the notice to mail.
What must be available before sending?
The request needs the letter PDF and recipient and sender details, and those details must be confirmed before sending.
