External Webhook-Driven Cache Invalidation
Your API sends a webhook. Notis purges the URL. No manual intervention needed.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Purge URL
Tool to purge a specific url from the bunnycdn cache. use when you need to invalidate a resource immediately after updating it.
Why this helps
External systems (APIs, build tools, monitoring dashboards) can't trigger CDN cache purges. Manual workaround is slow and error-prone.
- External systems can automatically purge cache without human intervention
- Faster content updates when systems detect changes
- No manual cache management needed for system-driven updates
- Integrates your entire stack without context-switching
Setup
Build it in a few focused steps.
- 1Connect Bunnycdn to Notis
- 2Ask Notis: 'Create a webhook URL that purges a specific URL when called'
- 3Notis will generate a unique webhook URL you can POST to
- 4Configure your external system to call this webhook when cache should update
- 5Test by calling the webhook and verifying the URL gets purged
Questions about this workflow
What format does the webhook expect?
Notis will give you the exact format. Usually a JSON POST with the URL to purge. Simple and standard.
Can I purge different URLs from different systems?
Yes. Create multiple webhooks, one for each URL or system, and configure each system to call its webhook.
Is this secure?
Notis webhooks use unique URLs so only systems you configure can call them. No authentication needed but hard to guess.
