Golang and google api - post request syntax while using oauth for devices status update

I am trying to change the status of the chromeos device.

My "get" request works with getting the device ID from the serial number.

However, I am not able to figure out how to pass the payload in golang google sdk/api, since it is a "post" request.

The payload in this case is the Action. (deprovision, disable, reenable, pre_provisioned_disable, pre_provisioned_reenable) and deprovisionReason if action is deprovision.

Getting error

cannot use deviceAction (variable of type map[string]string) as *admin.ChromeOsDeviceAction value in argument to srv.Chromeosdevices.ActioncompilerIncompatibleAssign

The method ChromeosdevicesService.Action takes ChromeOsDeviceAction:

chromeosdeviceaction := &admin.ChromeOsDeviceAction{
    Action: "disable",
    DeprovisionReason: "retiring_device",
}

Your code would be simpler and more portable using Application Default Credentials. This approach is shown and referenced in the library's documentation: Creating a client
