Manage devices
Device management is where most Fleets API workflows begin. MK.IO Beam is an on-premises media processing appliance, and the Fleets API is the cloud control plane for it. You register a device into a project, give it a site and the networks it can use, then move into backup, software, or diagnostic operations. For the on-device onboarding steps that precede registration, see Onboard a fleet device.
Register a device
A device is created with PUT, using its name in the URL. You associate the physical appliance with this record using either a shortCode or a locationId read from the device web interface.
curl -X PUT "https://app.mk.io/api/v1/projects/<PROJECT_NAME>/fleet/devices/beam-encoder-01" \
-H "Authorization: Bearer <YOUR_TOKEN>" \
-H "Content-Type: application/json" \
-d '{
"metadata": {
"displayName": "Beam Encoder 01",
"labels": { "location": "studio-a", "role": "encoder" }
},
"spec": {
"shortCode": "XU7U23WD",
"siteName": "headquarters",
"availableNetworks": []
}
}'
The fields that matter:
shortCode: the 8-character code from the device web interface. It rotates frequently, so use it promptly.locationId: a stable device identifier that does not rotate. Prefer it for scripted, large-scale onboarding.siteName: the site the device belongs to. See Set up networks and sites.availableNetworks: the networks the device may use. An empty array gives it access to every network with a route to its site.
After registration, the device web interface shows Registered: Yes.
Read the device and its status
curl -X GET "https://app.mk.io/api/v1/projects/<PROJECT_NAME>/fleet/devices/beam-encoder-01" \
-H "Authorization: Bearer <YOUR_TOKEN>"
The status block is where you watch the device's health and software. The fields worth tracking:
| Field | Tells you |
|---|---|
currentSoftwareVersion |
The version running now. |
softwareUpgradeState |
Idle, Switching, or SwitchFailed during a version change. |
alarmSeverity |
0 Clear, 1 Info, 2 Warning, 3 Error, 4 Critical. |
lastContact |
When the device last reached the cloud. |
The list endpoint supports $filter, $orderby, $top, $skiptoken, and label queries, including sorting on status/alarmSeverity and status/currentSoftwareVersion.
Update device settings
Use PATCH to change settings such as the site, networks, or software preferences:
curl -X PATCH "https://app.mk.io/api/v1/projects/<PROJECT_NAME>/fleet/devices/beam-encoder-01" \
-H "Authorization: Bearer <YOUR_TOKEN>" \
-H "Content-Type: application/json" \
-d '{ "spec": { "autoPreloadLatestSoftware": true } }'
The software-related fields (desiredSoftwareVersion, preloadSoftwareVersion, autoPreloadLatestSoftware) are covered in Software and updates.
What goes wrong
- Registration fails because the short code expired. Short codes rotate. Keep the device interface open so it shows the current code, or register with the non-rotating
locationIdinstead. - Deleting a device returns
409 Conflict. The device is still referenced, for example by an assigned flow. Clear the dependency, then retry the delete.
curl -X DELETE "https://app.mk.io/api/v1/projects/<PROJECT_NAME>/fleet/devices/beam-encoder-01" \
-H "Authorization: Bearer <YOUR_TOKEN>"
What comes next
- Backups and restores: protect device state before major changes.
- Software and updates: control desired and preloaded software versions.
