Stripe Card Token no longer works.
Also, if you use XHR instead of XHR2 function, the error returned is:
Script createCardToken: Error: com.mongodb.BasicDBObject cannot be cast to java.lang.String ( @ 43 : 18 ) - throw e;
I thought Appery support external api calls. If XHR and XHR2 aren't working, are there other ways?
