AWS IoT Core adds APIs for MQTT connection management

Today, [AWS IoT Core](https://aws.amazon.com/iot-core/) launches two new MQTT connection management APIs, GetConnection and ListSubscriptions, enabling you to easily access MQTT client connection and subscription information for your Internet of Things (IoT) devices. These APIs help you troubleshoot connectivity issues, monitor client behavior, and audit connection patterns across your device fleet. The [GetConnection API ](https://docs.aws.amazon.com/iot/latest/developerguide/mqtt.html#get-connection-api)gives you visibility into an IoT device connection by retrieving detailed connection information, including connection status, MQTT session details, and optional socket-level data such as source and target IP addresses, ports, and client VPC endpoint ID, controlled via granular IAM policies. The[ ListSubscriptions API](https://docs.aws.amazon.com/iot/latest/developerguide/mqtt.html#list-subscriptions-api) complements this by returning all topic subscriptions, including QoS levels for a client’s MQTT session, for connected and offline clients with persistent sessions. This enables you to validate and identify overlapping or unnecessary subscriptions that may impact solution performance. Together with the existing DeleteConnection API, these new APIs provide a comprehensive MQTT connection management experience. These APIs are now available in all AWS [regions](https://aws.amazon.com/about-aws/global-infrastructure/regional-product-services/) where AWS IoT Core is supported.
