Clear a Bunny pull zone cache from WhatsApp
When a broad refresh is intended, turn the request into a full pull zone purge.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Purge Pull Zone
Tool to purge the entire cache of a pull zone. use after updating origin or critical content to ensure no stale assets are served.
Why this helps
A full cache purge has a larger impact than refreshing one URL, so requests need to be clear and easy to review.
- Handle broad refresh requests from the chat where they arrive.
- Keep the requested pull zone in view for the run.
- Avoid manually switching to Bunny CDN to initiate the purge.
Setup
Build it in a few focused steps.
- 1Connect 2chat and Bunnycdn once in the Notis portal.
- 2Create an automation in Automations, New Automation, or tell Notis from any channel to create it.
- 3In one instruction, tell Notis to run a full purge only when the incoming WhatsApp request clearly identifies the pull zone and requests a full refresh.
- 4Choose the notis_webhook trigger and select where run reports should go.
- 5Test with one real request for a pull zone where a full purge is appropriate.
Questions about this workflow
Is this the same as purging one URL?
No. This uses the Purge Pull Zone action, which purges the entire cache of a pull zone.
Can Notis infer which pull zone to purge?
The request or your instruction needs to provide enough information to identify the intended pull zone. The available action description does not specify how the zone is selected.
Should I use this for every asset update?
Use it when a broad cache purge is intended. For a single resource, use a URL-specific purge workflow.
