Mark Important Asana Attachments with Slack Stars
A file is attached to an Asana task. That message gets starred in Slack. Important reference material is now easy to find when you need it.
Trigger
Attachment Added to Task
Triggers when an attachment is added to a task.
Action
Add a star to an item
Stars a channel, file, file comment, or a specific message in slack.
Why this helps
Neurodivergent founders struggle with file discovery. When documents, contracts, or designs are attached to Asana tasks, Slack users don't know to look for them. Files get buried in threads and forgotten.
- File discoverability: Starred messages are easy to find in Slack's Saved Items; important attachments don't disappear in thread noise.
- Lightweight organization: Stars are simpler than channels or threads for quick reference material.
- Automatic tagging: No need to manually star messages; Notis does it when the file arrives.
- Single source of truth: Files live in Asana for authority; Slack stars for quick access.
Setup
Build it in a few focused steps.
- 1Connect Asana and Slack to Notis.
- 2Tell Notis: 'Star Slack messages when files are added to Asana tasks.'
- 3Notis asks which Asana project and which Slack channel.
- 4Set 'Attachment Added to Task' as your trigger.
- 5Test by uploading a file to an Asana task; the relevant Slack message should be starred within seconds.
Questions about this workflow
Does this work for specific file types (e.g., only PDF or image files)?
Yes. You can filter by file type in your prompt: 'Star Slack messages only when designs are attached' or 'only when contracts are uploaded.'
What if the same file is attached multiple times?
Each new attachment triggers a star. If the message is already starred, Slack keeps it starred. No duplicates.
Can I use this with multiple Slack channels?
Create separate automations for different Asana projects or channels. Each automation routes attachments to its own channel.
