Samsung isn't making it easy for developers. The company may have released a handful of SDKs for its latest devices, but Samsung's non-committal approach to its Tizen platform is probably going to cost it developer support.
Pactas, recurring billing solution provider, offers the Pactas API that allows developers to include Pactas functionality within third party apps and websites. Any need for recurring billing (e.g. carsharing, music flatrates, cloud services, etc.) can be simplified and streamlined with the Pactas solution. Pactas enables users to manage subscriptions, track payments, and map pricing. Access to the platform can customize to each users' situation depending on need, resources, and integration opportunities.
