When I try to list a Motors Item I get the following error message even though the category is a leaf category:
<Errors>
<ShortMessage>Invalid
category.</ShortMessage>
<LongMessage>The
category selected is not a leaf category.</LongMessage>
<ErrorCode>87</ErrorCode>
<SeverityCode>Error</SeverityCode>
<ErrorClassification>RequestError</ErrorClassification>
</Errors>
Why am I getting this error?
Summary
When you list an Item, you need to ensure that the Category is at leaf level and also that it is not virtual.
Detailed Description
eBay Motors has some virtual categories apart from the regular categories that you see on the Site when you list an item. The virtual categories are meant for eBay internal use and is not meant to be used in any of the API calls. If you use a virtual category when listing an item, you will get the error message that it is not a valid category. You can make a call to GetCategories with the DetailLevel set to ReturnAll and find out which categories are virtual and to be ignored.
Here is a sample GetCategories request to get the top parent level categories:
<?xml version="1.0" encoding="utf-8"?>
<GetCategoriesRequest xmlns="urn:ebay:apis:eBLBaseComponents">
<CategorySiteID>100</CategorySiteID>
<DetailLevel>ReturnAll</DetailLevel>
<LevelLimit>2</LevelLimit>
<RequesterCredentials>
<eBayAuthToken>*****</eBayAuthToken>
</RequesterCredentials>
</GetCategoriesRequest>
