How can I use webhooks for delivery customization?

Topic summary

Main issue: A developer wants a reliable way to keep “Delivery Customizations” (Shopify Functions that modify shipping options at checkout) synchronized between their app and Shopify Admin. They worry that storing rules in their own database will become inaccurate because merchants can enable/disable/delete these customizations directly in Admin.

Key question: Are there Shopify webhooks that fire on create/update/enable/disable/delete events for Delivery Customizations so an external app can stay in sync without stale data?

Context: A screenshot (image) shows the Shopify Admin interface listing Delivery customizations, indicating functions are managed within Shopify. The image is central to understanding the request.

Status/updates: No solution or official guidance is provided in the thread. A second participant asks whether a solution was found, suggesting the question remains unanswered.

Outcome: No decisions or actions recorded. The discussion is open with the core need being event-based notifications (webhooks) for Delivery Customizations to prevent data mismatches.

Hi,

I would like to get information about Delivery Customizations via web hooks. All functions are stored in Shopify, and customers can delete/enable/disable them from the Shopify Admin panel.

If I store the rules in my database, I might have incorrect details because the merchant can delete them directly from the Admin panel.

Hello,
Have you found any solution on this.
