Management API

The Management API is how your own systems manage your OhrTech devices: everything a member of your organisation can do to a device in the OhrTech Portal, plus remote ADB and a remote control viewer you can put in your own web app.

• Base URL: https://api.ohrtech.net, versioned under /v1
• Format: JSON over HTTPS, errors as RFC 9457 problem details
• Reference: every operation, also as an OpenAPI document
• SDK: .NET (OhrTech.Management on NuGet). From any other language, call it directly or generate a client.

Management API or Device SDK?

Use the Management API from code that runs off the device: your servers, scripts and desktop tools, managing many devices at once. Code in an app running on an OhrTech device will use the Device SDK instead.

What it covers

Area	What you can do
Devices and fleets	List devices with live status (online, battery, network, OS, Agent version, settings state), read installed apps and enrolment history, ask a device to check in now, move devices between fleets
Settings	Read and change nearly 50 device settings, each set or locked; see what each device applied; push them again
Messages and tasks	Show a message on a device’s screen; follow every task OhrTech runs on it
Remote control	Open a session on a device and show it in your own app, with the consent your policy requires
Remote ADB	Open ADB sessions to devices anywhere, for your engineers
