I am trying to use the magento 1.x REST API to get product variants as well as options. I also have access to the SOAP API V2 with WS-I turned on.
I can't figure out how to find out if a product has variants and match it to those variants. I see complex and simple products but no way to link them.
Another issue I have is with options. For example if a product has S/M/L how do I retrieve those options?
