Remind Your Slack Team When External Systems Fire
External tool sends a webhook. Notis receives it. Slack reminder lands automatically. Your team acts before the moment passes.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Create a reminder
Create a reminder for a specified time.
Why this helps
Important events in external systems (GitHub issues, form submissions, deployment alerts) don't trigger Slack actions—teams miss them until they check each tool manually.
- Bridges external tools (GitHub, Zapier, APIs) with Slack reminders
- Eliminates manual checking of external systems
- Puts urgent events in front of your team immediately
- Enables custom workflows beyond pre-built integrations
Setup
Build it in a few focused steps.
- 1Connect Slack to Notis.
- 2Create a new automation: 'Webhook reminders to Slack.'
- 3Tell Notis: 'When I send a webhook to you, create a Slack reminder with the message I send.'
- 4Select 'Webhook' as the trigger and Notis will provide you with a unique webhook URL.
- 5Test by sending a test webhook from your external tool (curl, Zapier, or a script) and verify the Slack reminder appears.
Questions about this workflow
What format should my webhook payload be in?
Mention your preferred format in the automation prompt (JSON, form data, etc.), and Notis will guide the parsing or adjust the expected format.
Can I send different reminders based on webhook data?
Yes. Describe the conditions in your prompt: 'if priority is high, remind immediately; if it's low, remind in 1 hour.'
Is the webhook URL secure?
Yes, it's unique to your automation. Treat it like an API key and don't share it publicly.
