We want to use more than 3 types of notifications on our traccar server.

Mail

sms (traccar sms geteway)

is this posible just add the new notification code to the traccar.xml??

<entry key='notificator.types'>web,mail,sms</entry>
<entry key='sms.http.url'>https://www.traccar.org/sms/</entry>
<entry key='sms.http.authorization'>TOKEN</entry>
<entry key='sms.http.template'>
    {
        "to": "{phone}",
        "message": "{message}"
    }
</entry>
