Fortumo's Web SDK is a turnkey carrier billing solution for selling virtual currencies or goods in online games, web applications and social networks.
Web SDK can be called from any mobile app, on any platform, in a 100% transparent browser window - without the user even leaving the app. When detecting that user is on a mobile device, Fortumo's payment pages automatically morph themselves into slick, small-screen-optimized version of our payment flow.
Payment flow can be opened in a pop up (see demo payment button below), inside an iframe or new browser window. When calling a payment flow, different payment initialization parameters should be specified in order to make the payment experience for your users as seamless as possible.
