        // this function is called if getting a payment token was successful
        console.log("ClearentTokenSuccess");
        console.log(result);
    },
    (error) => {
        // this function is called if getting a payment token failed
        console.log("ClearentTokenError");
        console.log(error);
    }

   "exchange-id":"ID-clearent-mobile-jwt-1-c32bfe39-d454-4e34-8b4f-94d850643e48",
   "payload":{
      "mobile-jwt":{
         "jwt":"eyJhbGciOi23UzIh4iJ9.eyJsYXN0LWZvdXIiOiIxMrkP8iwid
                HlwZSI6Ik1BTlVBTCIsImV4cCI6MTU0NzY0NjU2MSwidG9rZW4iOiIxMTAwMDAw
