Delete derived assets when webhooks arrive
When your backend or external tool sends a webhook signal, Notis automatically deletes matching derived assets in Cloudinary, keeping storage lean.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Delete Derived Resources
Tool to delete derived assets. use when you need to remove specific derived assets by their ids. example: "delete derived assets with ids [id1, id2]".
Why this helps
Your app generates lots of derived assets in Cloudinary but nobody cleans up old versions, wasting storage and slowing down your account.
- Derived assets deleted automatically
- Storage stays optimized
- Cleanup triggered by backend events
- No manual intervention needed
Setup
Build it in a few focused steps.
- 1Connect Cloudinary to Notis from the portal.
- 2Tell Notis 'Delete derived assets in Cloudinary when I send a webhook signal' or set up with trigger kind notis_webhook.
- 3Notis will provide you with a webhook URL to share with your backend or external system.
- 4Your backend sends a POST to that URL with asset IDs to delete, and Notis deletes them from Cloudinary.
- 5Test by sending a test webhook with a sample asset ID and verify the derived asset is deleted.
Questions about this workflow
How do I send the webhook signal?
POST a JSON payload with asset IDs to the webhook URL that Notis provides. Example: {"asset_ids": ["id1", "id2"]}
What if an asset ID does not exist?
Notis skips non-existent assets and reports which deletions succeeded and which failed.
Can I schedule automatic deletion instead?
Yes. Switch to a cron trigger if you prefer daily or weekly cleanup on a schedule instead of event-based.
