Webhook Stock Changes

Webhook Stock Changes

Hi!
I created a webhook for item updates. Therefor, I created a Webhook under Automation > Workflow Actions for the Item-Module and a Workflow-Rule under Automation > Workflow Rules for the Item-Module.

Everything is working so far except the Stock. Is there a possibility to also trigger Stock Updates made by "Inventory Adjustment", "Purchase Orders", etc. That means only 1 hook to rule them all ^^

Or do I have to create extra hooks for all the Modules separately?
