Get Reminded in Slack When Asana Files Arrive
A contract or design is attached to an Asana task. Slack reminds you to review it within your preferred timeframe. No forgotten documents, no missed deadlines.
Trigger
Attachment Added to Task
Triggers when an attachment is added to a task.
Action
Create a reminder
Creates a slack reminder with specified text and time; time accepts unix timestamps, seconds from now, or natural language (e.g., 'in 15 minutes', 'every thursday at 2pm').
Why this helps
Document review is easy to forget for neurodivergent teams, especially when files are buried in Asana tasks. Documents pile up, and critical approvals get delayed.
- Timely review: Reminders surface files when they arrive, so documents don't languish.
- Document-specific: You can set different reminder times for different file types (contracts need faster review than designs, for example).
- Batch-friendly: Multiple attachments trigger multiple reminders, which stack naturally in Slack.
- No manual reminders: Stop creating review reminders by hand. Notis does it automatically.
Setup
Build it in a few focused steps.
- 1Connect Asana and Slack to Notis.
- 2Tell Notis: 'Remind me in Slack when files are attached to [Project]' or 'remind me in 2 hours.'
- 3Notis asks which project and reminder timing.
- 4Select 'Attachment Added to Task' as your trigger.
- 5Test by attaching a file to an Asana task; a Slack reminder should appear at your specified time.
Questions about this workflow
Can I set different reminder times for different file types?
Yes. Create separate automations: 'When contracts are attached, remind in 1 hour' and 'When designs are attached, remind in 4 hours.'
What if multiple files are attached to the same task?
Each attachment triggers its own reminder. If five files arrive, you get five reminders (which is great for attention allocation).
Does the reminder include a link to the file?
Yes. Notis includes a link to the Asana task so you can click straight to the file.
