Share Asana Attachments in Slack Automatically
A design is attached to an Asana task. Slack immediately posts it to the team channel. Everyone sees the file without digging through Asana.
Trigger
Attachment Added to Task
Triggers when an attachment is added to a task.
Action
Post message to channel
Deprecated: posts a message to a slack channel, direct message, or private channel. use `send message` instead.
Why this helps
File discoverability fails for distributed teams. Attachments in Asana are invisible to Slack users who live in their own tools. Important designs, contracts, or decisions go unseen.
- Team visibility: Attachments are posted to Slack so everyone knows when important files arrive.
- One-way flow: Files flow from Asana to Slack; team works in their preferred tool.
- Context included: Posts include task name and link so readers know the file's context.
- Searchable: Slack's file search makes attachments easy to find later.
Setup
Build it in a few focused steps.
- 1Connect Asana and Slack to Notis.
- 2Tell Notis: 'Post Asana task attachments to the [Channel] Slack channel.'
- 3Notis asks which project and which Slack channel.
- 4Select 'Attachment Added to Task' as your trigger.
- 5Test by attaching a file to an Asana task; it should appear in your Slack channel.
Questions about this workflow
Can I filter by file type?
Yes. Tell Notis: 'Post only design attachments' or 'only spreadsheets.' Notis filters by file extension.
What if multiple files are attached at once?
Notis posts each file to Slack. If five designs are attached, the channel gets five posts (or one thread with five files, depending on your preference).
Does the Slack post include a link to download the file?
Yes. Notis includes a direct link to the attachment so team members can download without opening Asana.
