Send Telegram Alert When Canvas Webhook Is Received
External systems send Canvas updates to a webhook, but your team doesn't hear about them. Notis catches incoming webhooks and sends Telegram alerts so nothing slips through.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Send Message
Send a text message to a telegram chat using the bot api.
Why this helps
Webhooks from third-party Canvas tools (enrollment systems, synchronization jobs, etc.) fire silently. Critical updates go unnoticed until something breaks.
- Know immediately when external Canvas tools send updates
- Build custom automation workflows outside Notis trigger library
- Catch integration errors before they impact course data
Setup
Build it in a few focused steps.
- 1Connect Canvas and Telegram to Notis.
- 2Create an automation: "When a webhook arrives, send me a Telegram message with the details."
- 3Notis generates a unique webhook URL for you to share with external tools.
- 4Provide the webhook URL to your Canvas sync tool or external system.
- 5Test by triggering the webhook from the external tool and confirming the Telegram message arrives.
Questions about this workflow
What does the webhook URL look like?
Notis generates a unique HTTPS URL (e.g., https://notis.app/webhook/abc123) that you provide to external tools.
Can I parse webhook data in the message?
Yes. Your prompt can ask Notis to extract specific fields from the incoming webhook and include them in the Telegram message.
Is the webhook secure?
Yes. Notis uses HTTPS and can validate webhook signatures if the sending tool supports it.
