IoT Platform provides API operations that are used to manage products, devices, groups, topics, rules, and device shadows. It also provides API operations that are used to send messages. To send an IoT Platform API request, you must use IoT Platform SDKs to send a GET or POST request over HTTPS or HTTP to the IoT Platform endpoint. You must add the request parameters that correspond to the API operation being called. IoT Platform handles the request and returns a result.
