Hi @sabangnet,

Days_9 is not a valid Listingduration value for the FixedPriceItem ListingType. The valid choice of ListingDuration values depends on the listing format.

For a list of valid values, call GetCategoryFeatures with DetailLevel set to ReturnAll and look for ListingDurations information. Currently you are not using the DetailLevel in the GetCategoryFeatures request.

Q1. Even if you enter the ListingDuration (GTC) inquired in the GetCategoryFeatures API, it is failing with the same message. It is failing even if you enter and send it to the GTC inquired in the FixedPriceItem, the same as the ListingType value in the AddFixedPriceItem API. Can you tell me why it is failing?
