 angular.module('appConstant', []).constant('shopSettings',{

   payPalMerchantPrivacyPolicyURL : 'url to policy',
   payPalMerchantUserAgreementURL : ' url to user agreement '

I integrated in my ionic app & successfully getting renderSinglePaymentUI but I am unable to use renderFuturePaymentUI, It goes in error callback saying "Passibly configuration submitted is invalid"
