Hi Thank you,
But this still does not answer my question regarding the key, by using API what field is the "ley" for Toolset fields that I can use to map the data and save it?
As you can see in YT video provided (23:59 and 24:27), it is very easy to get this from ACF, so how would it work for Toolset since when creating Custom fields I can only see the "Field name" and "Field slug"?
