Today, there are billions of smartphones acting as the main device to connect, access, and assess software applications any time, anywhere, and on any network. That is, all kinds of cloud, web, and enterprise applications are being stuffed with mobile interfaces. This mobility enablement has become the norm for application developers and providers. Not only applications, but also software and hardware infrastructures, are being fitted with mobile interfaces to enable remote monitoring, management, diagnosing, and repairs. In our everyday life, we encounter millions of mobile apps being developed and stocked in mobile stores. Smartphone users can download and install them with ease. Thus, these days, mobile, handheld, and wearable applications are receiving a lot of attention and affection from users and developers alike. We need competent mechanisms to attach APIs to these applications so that other applications/services can easily find and bind to come out with business-centric applications. There are several easy-to-understand and -use methods and mechanisms for producing technology-agnostic RESTful services and their APIs.
