Sync Asana Task Comments Directly to Slack

A comment arrives on an Asana task. Your Slack channel shows it instantly. No email forwarding, no screenshot sharing, no missed feedback.

Deprecated: posts a message to a slack channel, direct message, or private channel. use `send message` instead.

Why this helps

Discussion fragmentation breaks context for neurodivergent teams. When stakeholders comment on Asana tasks, other team members may never see those comments if they live in Slack. This creates misaligned assumptions and repeated questions.

  • Unified discussion: All task feedback lives in one Slack thread, eliminating fragmented conversations.
  • Context preservation: Comments include the task name and link so readers understand scope immediately.
  • No notification lag: Slack gets the comment instantly, so nobody misses critical feedback.
  • Async-friendly: Team can catch up on comment threads at their own pace via Slack, not forced real-time Asana checking.

Setup

Build it in a few focused steps.

  • 1Connect Asana and Slack to Notis.
  • 2Ask Notis: 'Post comments from Asana task [Task Name] to Slack' or specify a project.
  • 3Notis confirms the Asana project and target Slack channel.
  • 4Select 'New Comment on Task' as the trigger and pick a notification channel for run reports.
  • 5Test by adding a comment to an Asana task; it should appear in your Slack channel within seconds.

Questions about this workflow

Will every comment post to Slack, or can I filter by author or keyword?

Notis can filter comments by author (e.g., 'only post comments from the project lead') or keyword (e.g., 'only post comments containing urgent or block'). Specify this in your automation prompt.

Does Notis include attachments or links from Asana comments?

Yes. Notis extracts comment text, links, and references, and includes them in the Slack post. File attachments are linked so Slack users can click through.

What if I want different tasks' comments in different Slack channels?

Create separate automations for different Asana projects or task tags. Route each to its own Slack channel.
