Step-by-step walkthrough for finding item data and submitting reports
The current identifier for a specific item copy. Changes after every trade or market sale. Find it by dragging an item to the browser address bar in your Steam inventory. The URL ends with the asset_id.
/inventory#570_2_11153679536The asset_id from when the item first appeared in Steam. Never changes. Retrieved via the Steam API. When multiple items share the same original_id, they are duplicates.
Numeric identifier for the item type in Dota 2's schema. Same across all copies of the same item. Included in the API response. Optional when submitting but helps with display.
Open the owner's Steam inventory in a browser. Drag the item into the address bar. The URL will look like:
steamcommunity.com/id/.../inventory#570_2_ASSET_IDThe last number is the asset_id.
Call the Steam API to retrieve the item's original_id. You'll need a Steam API key and the owner's SteamID64.
https://api.steampowered.com/IEconItems_570/GetPlayerItems/v1?key=YOUR_KEY&steamid=STEAMID64In the JSON response, find the item by its asset_id. The original_id field is what you need.
If asset_id β original_id, the item has been traded β this is normal.
If you find multiple different items sharing the same original_id, duplication has occurred and the item can be reported.
Go to the Report Dupes page and submit the asset_id, original_id, and optionally the defindex. Sign in with Steam to submit. Your report will go through community verification before it is used.
