Well, the replies I have received from support are just too generic to help me, they are not specific enough. If you look at that thread (link above) you will see that there was not one bit of specific advise until Oleg responsed telling me about REST services but I have struggled to understand how to apply the information that was contained in the links he provided.
I obviously don't have the technical know-how required for this platform. I chose Appery.io because it was pitched as something suitable for non developers but it is clear now that in order to do anything in any way useful you require JS skills which I don't have.
