Hi When I use the .net SDK and using the APIContext with ApiCrendential class I have found numerous examples where only the usertoken is supplied. I also only supply the usertoken and havent found any problems so far. Can I ask what the other keys are supplied for? e.g. App Id, Cert Id and Cert secret? Not sure why they are there if they are not required? I'm sure there is an obvious reason. I probably haven't read up enough?
