So you might have noticed there's now an option on the companion app and on Bungie.net allowing you to lock/unlock your items. Here's what you need to use it: [edit] It's worth noting that the characterId needs to be valid or else the API call will fail, so if you want to lock items in your Vault, you need to reference a character in your request. [quote]API: POST /Platform/Destiny/SetLockState/ { state: true, // true/false membershipType: "2", // 1 for xbox / 2 for playstation characterId: "{characterId}", itemId: "{itemInstanceId}" }[/quote] There are 2 variables in itemInstances you will want to look at as well: - lockable - locked Finally here's the url for the icon bungie is using to display the locked status.
