Deadline Visibility: Never Miss a Due Date Again
Due date set in ClickUp. Slack reminder created. When that date approaches, you get reminded in Slack. No email chains, no ClickUp tab refreshing. Just timely awareness.
Trigger
Task Due Date Updated
Triggers when a task's due date is set, changed, or cleared. `changes[]` carries `DueDateChange` entries only; `before` and `after` are millisecond-epoch strings or `null`.
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
Deadlines get set in ClickUp but somehow go unnoticed until the last minute, causing stress and rushed work. Or they're forgotten entirely and delivered late.
- Deadlines surface in your primary communication tool (Slack)
- Reminders are persistent and hard to miss
- Reduces deadline anxiety by catching changes early
- No need for separate calendar management
Setup
Build it in a few focused steps.
- 1Connect ClickUp and Slack to Notis via the portal
- 2Create an automation: 'When a due date is set or updated in ClickUp, create a Slack reminder'
- 3Specify how many days before the due date to remind (e.g., 2 days before, 1 day before, same day)
- 4Select 'Task Due Date Updated' as the trigger
- 5Set a due date on a test task in ClickUp and watch the Slack reminder appear
Questions about this workflow
Can we set different reminder times based on task priority?
Yes. You can ask Notis: 'High-priority tasks remind me 3 days before; others remind me 1 day before.'
What if we have hundreds of tasks with due dates?
This automation only triggers when due dates are *changed*, not retroactively for existing dates. It's forward-looking to prevent notification overload.
Can we include task details in the reminder?
Yes. Notis can include the task name, assignee, description summary, and any custom fields in the reminder text.
