Description: Machine-to-Machine (M2M) APIs are programming interfaces that enable direct communication between devices without human intervention. These APIs are fundamental in the context of the Internet of Things (IoT), where multiple devices connect and share data autonomously. Through these interfaces, devices can exchange information, perform actions, and make decisions based on real-time data. The main features of M2M APIs include the ability to operate over diverse communication networks, such as cellular, Wi-Fi, and Ethernet, as well as the capability to handle large volumes of data efficiently. The relevance of these APIs lies in their ability to optimize processes, improve operational efficiency, and facilitate automation across various sectors, from industrial applications to smart homes. In summary, M2M APIs are an essential component in the evolution of connected technology, allowing devices to work together effectively without the need for constant human intervention.
