The Ebay Category Taxonomy and category list can be found here.
The Ebay Category Taxonomy has about a thousand categories. It is recommended to get the category as specific as possible, usually when a leaf node is reached, however specificity is not required as long as a valid numeric ebay category is specified in the required ebay category.
