At its core, IoT is all about data: data from devices, commands to devices, integrating IoT data with other data to gain insights. The data sources include devices, enterprise applications, vendor/partner systems, service providers and customers. The point-to-point integration between these various systems is not feasible; hence, APIs become the primary means of communication between these disparate systems. A clean architectural approach is the one suggested by the agile integration concept. APIs are central to this concept, which allow data to be shared securely between internal and external systems. The opening of APIs enables a company to provide uniform data and transaction interfaces to internal and external developers, partners, and customers, for improved data access and control of remote resources. By providing well-defined APIs, developers can use data in a programmatic manner; e.g., app developers can get access to IoT devices data without worrying about the underlying hardware interfaces. Considering the importance of APIs for IoT, it’s imperative for an organization to manage these APIs effectively. In fact, APIs have been called a fundamental enabler of IoT however, without an effective API Management solution, API sprawl can easily lead to catastrophe.
