Give shared PDFs a consistent finish
Repeated reports and handouts can arrive with different formatting. Add a standard header or footer when a PDF is shared in Slack.
Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Action
Add PDF Header Footer
Tool to add HTML header and footer to a PDF. Use when you need to embed consistent headers or footers across pages with margin and range options.
Why this helps
Adding the same presentation details to each recurring PDF takes time and creates inconsistent copies.
- Apply consistent presentation details to shared PDFs.
- Reduce repetitive document cleanup.
- Make recurring reports easier to recognize.

- 1Connect Slack and Encodian to Notis once in the portal.
- 2Create an automation and describe the header or footer you want in one plain-language prompt.
- 3Pick the Slack Channel Message Received trigger and select a reporting channel for runs.
- 4Test with a sample recurring PDF shared in Slack.
