Get Category IDs for Product via Service Contract / API

Question

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.

Answer 1

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.
