Know what a shared file is before opening it
Turn a Slack file mention into a quick properties check, giving you more context before deciding which document to open.
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
Get File Properties
Tool to retrieve properties of a file. Attempts multiple Encodian Filer endpoints and fallbacks.
Why this helps
A stream of file links makes it hard to identify which document needs attention first.
- See properties for a relevant file without opening it first.
- Make document triage more informed.
- Keep file review anchored to the original Slack conversation.
Setup
Build it in a few focused steps.
- 1Connect Slack and Encodian to Notis once in the portal.
- 2Create an automation with a plain-language prompt describing which file references to inspect and which details to report.
- 3Pick the Slack Channel Message Received trigger and select a reporting channel.
- 4Test with a channel message that references an accessible sample file.
Questions about this workflow
Can it inspect any cloud storage provider?
Encodian attempts multiple Filer endpoints and fallbacks, but the file must be accessible to the connected service.
Does the workflow open every link in a message?
Describe the relevant file types and references in the prompt so Notis focuses the check on useful documents.
