Hello!
I've installed this API Plugin to my store: https://www.nopcommerce.com/p/2464/api-plugin.aspx - Up until now I've not really stumbled upon any problems and can access products, categories, orders, customers etc without problems. However, now I'm trying to access attributes, and regular product attributes are fine. But what I want to access are the specification attributes. The regular product attributes are listed under the JSONProperty "attributes" on a product, but nowhere to be found are the specification attributes.
Any ideas? I will post a solution here if I find it myself before getting help.
