For testing purposes I've setup a REST Guest role with "All" access across the Catalog in my store, so I can throw some queries at the API whilst I find my feet.
Using Simple REST client in Chrome I can issue a GET request to http://www.mystore.co.uk/api/rest/products/1/categories which in theory should return the name of the category(ies) that product ID 1 has assigned to it?
I'm getting a success (200 - OK) response but the only actual data I get returned in Simple REST Client is "[]" rather then the name of the category that product ID 1 is in. I've verified that the product definitely has a category assigned.
Any ideas where I'm going wrong?
