Notis

Combine submitted PDFs into one packet

Send a request with the PDF URLs and get one combined document without a manual merge step.

Trigger

Webhook received

Notis starts this workflow when an external tool or custom backend sends an HTTP request.

Action

Merge multiple PDFs into one

Tool to merge multiple PDF files into a single PDF. Use when you have multiple PDF URLs and want one combined PDF.

Why this helps

Collecting several PDFs into one packet adds small but distracting admin work.

  • Combine submitted documents in one run.
  • Reduce repetitive file handling.
  • Make a packet easier to review or share.

Setup

Build it in a few focused steps.

  • 1Connect CustomJS once in the Notis portal.
  • 2Create an automation in Automations, New Automation.
  • 3Tell Notis to merge the PDF URLs supplied with each request into one PDF.
  • 4Pick a Notis webhook trigger and choose where run reports go.
  • 5Test with one real request containing multiple PDF URLs and review the result.

Questions about this workflow

What should the webhook request include?

It needs to provide multiple PDF URLs that CustomJS can use for the merge.

Can it merge files that are only in Drive without URLs?

The merge action expects PDF URLs, so the request or instruction must provide accessible URLs.

ActionInstant

File Shared (Permissions Added)

Triggers when new sharing permissions are granted to a file or folder. Uses Drive's `changes.list` endpoint with inline `permissions` in the `fields` mask so each change carries the file's current permission set provider-atomically. We diff that against `seen_permission_keys` to identify newly added grants. Drive page tokens are the primary cursor; if Drive rejects a stored token, the trigger raises `PollingTriggerError` without clearing state rather than silently re-baselining and dropping events. Limitation: truly ephemeral permissions (added and revoked between two polls without any other file modification in between) are not detected. Drive Activity API would catch those but requires an additional OAuth scope and a different payload contract.
