In Magento 2, is there a way to get the assigned category ids for a given product, via Service Contracts?
The CategoryLinkManagementInterface API interface only has one method that returns the assigned products for a given category ID, but I need it the other way around.
I haven't found such method from the service contracts.
The only way I can see this working via a service contract is by using Magento\Catalog\Api\ProductRepositoryInterface to get the product first (via get or getById ) and then call getCategoryIds on that product.
getCategoryIds is also not part of Magento\Catalog\Api\Data\ProductInterface, so I'll end up with a leaking abstraction. But it looks like this is unavoidable currently.
