月光下漫步

A previous offer's corresponding tradeid couldn't be found in the trade history API because the previously saved time_updated value was not the latest—it had changed. By using the updated time_updated value, the corresponding tradeid can be found in the trade history.

In GetTradeStatus, even if a trade is rolled back midway, it still returns a success status (3). It has been observed that when using the start_after_time parameter in the GetTradeHistory API, there are still cases where the corresponding tradeid is not returned—approximately 1 out of every 20 trades. Therefore, it’s still necessary to paginate through the results to locate it.

Retrieve time_updated from the Trade Offer API First, use the Steam Trade Offer API to get the time_updated field of the target trade. For example: https://api.steampowered.com/IEconService/GetTradeOffer/v1/?tradeofferid=8301957547&access_token=xx.xx.xx { "response": { "offer": { "tradeofferid": "8301957547", "tradeid": "807950398061201297", "time_updated": 1753501576, ... } } } Use time_updated as the start_after_time parameter to query the Trade History API Next, pass the time_updated value as the start_after_time parameter when calling the Trade History API: GET https://api.steampowered.com/IEconService/GetTradeHistory/v1/?max_trades=1&start_after_time=1753501576&access_token=xxx.xxx.xxx The API response will include the trade information starting from that timestamp: { "response": { "more": true, "trades": [ { "tradeid": "807950398061201297", "time_init": 1753501576, ... }, ... ] } } This method allows you to accurately locate a trade in the trade history using the time_updated value, which is useful for tracking or further processing.
