# Devices

> Device identity and ownership across Infuse-IoT Cloud and Infuse-Marketplace.

Devices are identified by device IDs and owned through the relevant provider or customer organisation.

Infuse-Marketplace checkout and install flows use device IDs to decide where purchases and installs apply. Provider storefronts must collect or resolve device IDs before creating checkout sessions.

Infuse-IoT Cloud is the source of truth for current device registry workflows. Backend integrations should resolve devices through [Infuse-IoT Cloud devices](/docs/infuse-iot-cloud/devices) before using those `deviceId` values in Infuse-Marketplace checkout, installs, telemetry ingestion, or command workflows.
