As I have purchased API , I am trying to send bet using fairlay sample client API (C# language) , I am using changeOrders function and getting error "XError:Wrong Signature" .
The sample client does everything for you. Just follow the steps outlined in the readme file of the C# sample client.
I have download sample client , replace the API ID in config file , generate public and private keys using configdet class and then call changeorders function , and got error "XError:Wrong Signature" , am i missing something?
