Abstract: This disclosure relates generally to Internet of Things (IoT), and more particularly to method, system, and framework for implementing IoT applications. In one embodiment, a method is provided for implementing a software application for an IoT device. The method may include defining, by an IoT implementation framework, a set of events and a set of actions for the IT implementation based on a process flow and configuration metadata. The method may further include creating, by the implementation framework, a set of custom actions, for the IT implementation, based on the set of events, the set of actions, and the configuration metadata. The method may further include processing, by the implementation framework, a set of messages received from the IoT device based on the process flow, the set of custom actions, and a set of pre-built actions.
