Message-Driven Bean implementation class for TelegramAlertingJob in SAP PI/PO. Sends messages from standard JMS queue alertingVP to Telegram channel via bot.

1. Create public channel with public link (@nickname)
2. Create bot via @botfather
3. Add bot to channel as admin

1. Operations->Jobs and open Java Scheduler

2. On Java Scheduler screen go to tab Tasks and click the Add button

3. Select TelegramAlertingJob

4. Enter Job Parametres

alertConsumer: name of a consumer that was set in SAP PO Alert Rule. This is used as a name for JMS queue in alertingVP.

maxAlertCount is max count of consumed alerts from JMS queue

apiToken: can be retrieved from BotFather;

chatId: id of telegram channel (described below in How to get id of private telegram channel)

5. Do not forget to set back channel as private one unless you want everyone to see a mess in your system ^^
6. Set timer parameters. Running job every 2 min would be enough and much more representative than emails.

7. Finish the job configuration. As a result you will find a job on Tasks tab

• Add bot as administrator to channel
• Set channel as Public channel and set channel nickname like @nickname
• Send message using https request: https://api.telegram.org/{botToken}/sendMessage?chat_id=@{channelNickName}&text=*test*&parse_mode=Markdown

As a result you will get JSON including real chat id:
