AWS IoT Core adds APIs for MQTT connection management

AWS IoT Core

AWS 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.

GetConnection API

The GetConnection 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.

ListSubscriptions API

The ListSubscriptions API returns 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.

What to do

• Use the new APIs to troubleshoot connectivity issues.
• Monitor client behavior and audit connection patterns.
• Validate and identify overlapping or unnecessary subscriptions.

These APIs are now available in all AWS regions where AWS IoT Core is supported. To learn more, visit the AWS IoT Core documentation and AWS IoT Core API reference guide.
