Updated quantity in inventory_levels/update webhook

[vinh0225]

How to get the updated quantity of inventory when capturing inventory_levels/update webhook?

The payload contains only inventory_item_id, location_id, available, updated_at and admin_graphql_api_id.
Why Shopify team doesn't add updated_quantity here? Or is there any other alternative solution?

Here is the payload example:

{
  inventory_item_id: 48083112919313,
  location_id: 87276519697,
  available: 50,
  updated_at: '2023-11-24T02:30:21-05:00',
  admin_graphql_api_id:
'gid://shopify/InventoryLevel/123788624145?inventory_item_id=48083112919313'
}
