|appid||uint32||✔||32bit App ID of the application associated with the assets.|
|owner||uint64||✔||The 64-bit Steam ID of the current owner of the asset or currency.|
|contextid||uint64||✔||The 64-bit ID of the context in which this asset or currency can be found.|
|assetid||uint64||The 64-bit asset ID being removed. Either assetid or currencyid will be set to indicate which kind of object should be set to unowned.|
|currencyid||uint32||The 32-bit currency ID being removed. Either assetid or currencyid will be set to indicate which kind of object should be set to unowned.|
|amount||uint32||The number of the asset or currency to remove. This number will always be 1 for non-stackable assets.|
It will always be less or equal to the amount that the Steam Economy server believes is present for this asset/currency in this context. Defaults to 1.
|trade_start_time||uint32||✔||The time the trade session responsible for this action started, expressed in seconds from Jan. 1, 1970.|
|audit_action||uint32||✔||A 32-bit number that specifies what kind of action is causing this asset or currency to be set unowned.|
|audit_reference||uint64||✔||A 64-bit number that identifies which event is action is associated with. The asset server may wish to record this number for auditing and debugging purposes.|
|leave_original||bool||✔||If this boolean parameter is set to 1 (to indicate true), then the asset server is being asked to duplicate the item and create a new unowned item that is a copy of the asset specified. This will only be true for one-sided undos of a trade a support agent. Defaults to 0 (false).|
|request_repeated||bool||✔||If this is set to 1 (to indicate true), then the Steam Economy server is indicating that it has made an identical request to this one at some point in the past but did not receive a clear success or failure. If it appears that the asset or currency has already been set to Unowned for the same audit_action and audit_reference, the asset server should return success and set new_assetid and new_contextid to whatever was returned on the first request.|
|is_market||bool||✔||If this is set to 1 (to indicate true), then the request is being performed in response to some activity on the Steam Community Market.|
success- True if the method was successful. If the asset server is returning false, it should set
errorto a string that explains why.
should_retry- By default, Steam will retry TradeSetUnowned calls until the request succeeds. It does this to make sure the item is a consistent state before deciding what to do next. However, for a permanent failure where you know that retries will not change the response (for example, if the item no longer exists), you can set the value of this field to 0.
error- a string describing why this call failed. This message will be recorded in the error log, which is available under the Economy tab on the Steamworks site.
new_assetid(optional) - The 64-bit asset ID of the unowned version of this asset. This is only set for asset transfers. This could be a new asset ID or be the same as the asset id specified in the request depending on how the implementation of the asset server.
new_contextid(optional) - The 64-bit context ID of the unowned version of this asset or currency. This could be a different context ID or be the same as the context id specified in the request depending on how the implementation of the asset server. Defaults to being the same as the context ID that was passed in.
