Web API: InventoryService AddItem problem

[Indigowd]

I recently started looking into setting up storing items with the Steam service, but I've run into problems. I am able to get all rest API calls that use GET to work correctly as I am testing (such as GetItemDefs). I am using my publisher Key, and the item I manually set up through the UI does get returned as expected.


But when I go ahead and try to add this item to a player (myself) using AddItem with a POST rest call, I end up getting a Forbidden message indicating that my key= parameter is wrong. It shouldn't be wrong though, since it is using the same key as the GET call that works.


Am I missing something really obvious? Is there a particular reason why this won't work?

I am making the call using VaRest plugin in UE4.

If anyone can point me in the right direction, I'd be ever grateful. The steam documentation isn't getting me any further, unfortunately.

Thanks!

I'm not sure if the key depends on whos profile you're sending the POST call to.
