Hi Mitchell,

Great to hear. The below should work for you.

Method:POST 

URI: https://<SERVERID>.mobicontrolcloud.com/mobicontrol/api/devices/<DEVICEID>/actions

Authorization: Bearer Token

Body:

{
  "Action": "SendMessage",
  "Message": "Test",
  "SendBy": "MobiControl",
  "QueueForOfflineDelivery": "true",
  "DisplayDuration": "UntilPressOk",
  "MessageType": "Information"
}

I imagine only action and message are required in the body, but worth knowing the other parmeters too.

FYI:

If you need to get DeviceID, then get all devices and DeviceID is listed as one of the returned value pairs

In my above image I get Device ID based on a search for Hardware Serial (Note these need to be URL encoded (twice is think)

FYI:

The documentation is fairly limited on APIs, one of the most helpful pieces of advice I had when using the APIs was the following. In Mobicontrol, select your device and choose your action e.g. SendMessage. Before pressing send, press F12, network and expand the action. This (in come cases) give you an idea of what the Method/URI/Body etc are for the actions. They wont always give you the exact answer youre looking for but are usually more helpful than the documentation.
