Automate Slack reminders from your Airtable deadlines
Stop manually setting Slack reminders for every Airtable deadline. Notis automatically creates reminders timed to keep you on track, so you never miss a milestone.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
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
You copy deadlines from Airtable to Slack reminders manually (if at all), which adds friction and means some dates never get reminders at all.
- Never manually create Slack reminders again
- Ensure every deadline has a built-in alert
- Set reminders for days before (not day-of) so you can plan ahead
- Reduce the cognitive load of juggling dates across platforms
Setup
Build it in a few focused steps.
- 1Connect Airtable and Slack to Notis (one-time).
- 2Create an automation: 'When a new deadline is added to [Airtable table], create a Slack reminder for [X days before] the due date.'
- 3Select 'Webhook' as the trigger to accept incoming deadlines.
- 4Configure the reminder timing (e.g., '3 days before', 'the morning of', 'a week prior').
- 5Send your first test deadline through Airtable and confirm the Slack reminder appears at the right time.
Questions about this workflow
Can I set different reminder times for different types of tasks?
Yes. Create separate automations for each category (e.g., client deadlines get a 5-day reminder, internal tasks get 2-day reminder).
What if I change a deadline in Airtable after the reminder is set?
The original reminder will still fire at its scheduled time. You can manually delete it in Slack or create a new automation to update reminders based on changes.
Do reminders work for recurring deadlines?
If your Airtable table has a recurring field, you can ask Notis to create reminders for each occurrence automatically.
