I've had various errors trying to get this to work with cJsonHttpTransfer

I now seem to have it "working", as in it's Friday night and I am now getting my first 200 not 400/401 back

With everything else correct the magic line sems to be

Get AddHeader "accept" "*/*" to bOK

It may not be the whole story but it is Friday night and I have a 200 so switching off before something else goes wrong
