Ebay says that GetCategorySpecifics API method is going to be deprecated by 31 Jan 2022. So developers have to migrate to Taxonomy API and use getItemAspectsForCategory call instead. But there is not a single field in this API saying that the category has a picture required or enabled. For GetCategorySpecifics call there is a field called Recommendations.NameRecommendation.ValidationRules.VariationPicture.
How can developers retrieve information about availability of variations specifics' pictures from Taxonomy API? Or is there any other way for doing this?
