So there's a great new API "/Platform/Destiny/TransferItem/" which takes the following values. { characterId: "2305843009221011538", itemId: "0", // itemInstanceId for weapons and armour, zero for everything else itemReferenceHash: "2904517731", // itemHash membershipType: "2", stackSize: 1, // specify how many you want to transfer, 1 for weapons and armour transferToVault: false, // true to send to the vault, and false to pull from it } There is also a new variable on items called "transferStatus" with the following values I have so far seen: 0 = Can be transferred 1 = Is Equipped, so can't be transferred 2 = Not Transferable (aka Bounties/Mission Items etc) 3 = Equipped Sub Class? Not sure what's the purpose of this one... [edit] There's also a "location" variable on items you can use to determine where an item is currently sitting: 1 is on a character, 2 is in the vault. I am really looking forward to seeing third parties make use of this one :D
