I would like to get data from a business that offers API (JSON result) on some product properties, but not all. As I do not have a technical question about using the API, or getting the other properties, my question is more on finding the best way to get these properties. For this reason I won't ask on Stack Overflow.
Is there a recommended site on Stack Exchange to ask for locations / access point / use of APIs? (Alternatively, URL for a mobile site) Or am I better off asking in other sites outside Stack Exchange?
