Send Commands to GPS tracker device

Hi
I want to send command to the GPS device, and the device uses watch protocol.
The message that I want to send the device as follow: [SG*8800000015*0009*UPLOAD,10]
My question is How to send this command to the device using API commands that is a JSON as follow:

http://{host}:{port}/api/commands:
{
"id": 0,
"deviceId": 0,
"description": "string",
"type": "string",
"attributes": { }
}

If the API doesn't support this command, can you tell me what is the best way to send this command to the device using web app Traccar platform

You can probably send it as a custom command UPLOAD,10.

Like this:

http://{host}:{port}/api/commands:
{

"id": 1,
"deviceId": 15,
"type": "custom",
"attributes": {"UPLOAD":10 }

}

No. Try sending it via web app and check what command is sent using browser developer tools.

Thank you very much.
