In the notificationServices setting you can add your own services like telegram service, for example:

"notificationServices": [
  //...
  {
        "serviceName": "testTelegram", // is notification service name which called from notifications
        "notificationType": "TelegramService", // declare service action type and is must important to have correct type.
        "username": "@NameOfBot",
        "apiKey": "684394290:AAFg3Ht1EtNB7iYe9V_VVxKCEVMP-lSjycA",
        "senderBot": "@NameOfBot",
        "isDefaultService": true // can be used for system notifications
  }
  //...

Enter channel or group name like @testChannel in the notification receiver. for example:

"notifications": [
    //...
    {

      "receiver": "123456789, @testChannel"
    }

• list of your jobs by types:
  • FireAndForget (this jobs are executed only once and almost immediatelyafter creation)
  • Delayed (this jobs are executed only once too, but not immediately, after a certain time interval)
  • Recurring (this jobs fire many times on the specified schedule)
• list of default notifications receivers
• list of notification services by type:
  • Email (this service provide send mail from your special mail service data)
  • Sms (this is a Short Message Service provider)
  • Telegram (this service is for send notifications from a telegram bot to a channel or group which the bot is administrator user member of that)
  • Slack (this service provide a webhook url to send notifications to your slack channels)
  • CallRestApi (is a provider to call or send notifications for your Restfull APIs, must times used for monitoring the APIs)

For example of the below setting, you can see that slack notification service defined in notificationServices part and by type SlackService and name testSlack which called from notifications part for service provider.

And in notifications part used SlackService for alerts channel as notification receiver. This part can define notifications to all jobs as deault receiver, but if a job have self notification definition, so just will send notify to that.
