Extend Canvas Automation Beyond Standard Triggers
Your Canvas data lives in multiple systems. Route custom Canvas events to Slack via Notis webhook—when your scripts or external tools detect specific Canvas activity, they can trigger Slack notifications in real-time without rebuilding integrations.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Post message to channel
Deprecated: posts a message to a slack channel, direct message, or private channel. use `send message` instead.
Why this helps
Standard Canvas triggers don't cover your specific workflow. You want to detect custom patterns in Canvas (e.g., submissions with specific keywords, late submissions, incomplete grades) and notify Slack, but the LMS doesn't have those granular triggers.
- Unlimited custom triggers beyond Canvas's standard events
- Connect any system that can POST to Notis
- Detect complex patterns and alert in real-time
- No code needed—plain language prompt handles the logic
Setup
Build it in a few focused steps.
- 1Connect Canvas and Slack.
- 2Create Automation: Name ('Custom Canvas Events'), Prompt ('When a webhook request arrives with Canvas data, post a message to Slack with the event details'), Channel (your monitoring or team channel), Trigger ('notis_webhook').
- 3Your external tools or scripts can now POST to Notis and automatically trigger Slack messages.
Questions about this workflow
How do I send a webhook to Notis?
Notis provides a unique webhook URL after you create the automation. Include it in your external tool's config and POST JSON data whenever an event occurs.
What format should the webhook data be in?
JSON is standard—Notis will parse it and include relevant fields in your Slack message.
Can I trigger other actions besides posting to Slack?
Yes—adjust your prompt to create reminders, archive channels, or other Slack actions based on the webhook data.
