This call is rate-limited by the user, so property modifications should be batched as much as possible (e.g. at the end of a map or game session). After calling [Set Property](/old-kb/old-toolkit-for-steamworks/unreal/blueprint-nodes/functions/set-property.md) or [Remove Property](/old-kb/old-toolkit-for-steamworks/unreal/blueprint-nodes/functions/remove-property.md) for all the items that you want to modify, you will need to call [Submit Update Properties](/old-kb/old-toolkit-for-steamworks/unreal/blueprint-nodes/functions/submit-update-property.md) to send the request to the Steam servers. A [Steam Inventory Result Ready](/old-kb/old-toolkit-for-steamworks/unreal/blueprint-nodes/events/inventory-results-ready.md) callback will be fired with the results of the operation. ### Return Value Returns an Update Handle that can be used with Set Property, Remove Property and Submit Update Properties. ## Nodes
