Send document letters from a Notis webhook
Connect an existing system's ready signal to a physical letter, with Notis checking that the mailing details are complete.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
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 completed document process can still require a manual handoff before the letter gets printed and mailed.
- Bridge a ready signal from another system to physical mail.
- Reduce repetitive handoffs after document completion.
- Keep recipient and PDF confirmation part of the instruction.
Setup
Build it in a few focused steps.
- 1Connect Docupost once in the Notis portal; connect any other app involved if needed.
- 2Create an automation in Automations, New Automation, or tell Notis from any channel.
- 3In one instruction, say to send the letter when the webhook indicates readiness and recipient, sender, and PDF URL are confirmed.
- 4Pick a webhook trigger and choose where run reports go.
- 5Test with one real HTTP request and verify letter details before sending.
Questions about this workflow
What starts this workflow?
An HTTP request to the Notis webhook starts it. The request should provide the context your instruction needs.
Does the webhook generate the PDF?
No. The letter action uses a PDF URL supplied by the request or otherwise available to Notis.
