- Keep the request and its originating chat together.
- Reduce the chance that users keep seeing stale content.

- 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 identify a Bunny CDN URL in the incoming WhatsApp request and purge that URL.
- 4Choose the notis_webhook trigger and select where run reports should go.
- 5Test with one real WhatsApp request containing a URL you intend to purge.
