Device Lifecycle
How a device moves from its first registration through active monitoring to decommission, and what each status value means.
Concepts
This section explains the building blocks of OTA-Pulse. If you have already followed the Getting Started guide and have a device showing up online, these pages will give you a mental model of what the system is doing under the hood and why it works the way it does.
Each concept corresponds to a first-class object in the API and the console. Understanding them will help you design your fleet topology, plan rollouts, and troubleshoot failures without guesswork.
Deployments
What a deployment is, how the server tracks per-device progress, and how to pause, cancel, retry, or roll back in-flight updates.
Artifacts
The Mender artifact format, signing algorithms, storage location, and what happens during upload.
Roles and Access Control
The four roles, what each can do, how organizations scope resources, and how API keys grant machine-to-machine access.
For endpoint-level details — request shapes, response schemas, and error codes — see the API Reference.
