To let Dex manage a Windows device, you install the Dex agent on the machine and enroll it with your account — there is no per-device API key to copy.
Steps
1In the Dex admin console, open the Devices section and choose Add Windows Device.
2Copy the generated enrollment/install token, or download the pre-configured Windows installer (.exe/.msi).
3On the Windows device, run the installer as Administrator, or push it silently via Intune, GPO, or a PowerShell command, passing the enrollment token.
4Wait for the device to check in — it appears as Online/Enrolled in the Dex Devices list.
5(Optional) Assign the enrolled device to the correct organization/site in Dex.
Paste into Dex
The connection form in the Dex app store asks for these values:
Enrollment / install token
Embedded in the installer or passed at install time; links the device to your Dex account.
