To set up a Telegram group for a major incident, do the following:

On the Administrator's computer

1. Download and set up Infrastructure Agent.

2. Create a Telegram client. 

   Info
   To create a Telegram client, complete the steps below: 1. Get registered in Telegram, using any client name. 2. Follow the https://my.telegram.org link for authorization. 3. Complete the form on the https://my.telegram.org/apps website to receive the URL and parameters of api_id and api_hash needed for the users' authorization. It is possible to link only one api_id to the telephone number.

   
   

3. Download a script archive, and add the scripts to the SIMPLE_MID_SERVER folder downloaded at the Step 1. 
   The four scripts in the folder are:
   
   • createGroup – to create a group,
   • cancelGroup – to restrict commenting upon the completion of the incident and changing its state to Completed,
   • deleteGroup – to delete a Telegram group,
   • clientInformation – to store api_id and api_hash.
4. Open the "clientInformation" script and add the api_id and api_hash values received when creating a Telegram client.
5. Run the "createGroup" script manually.
6. Complete the user's authorization that the system will require. As a result, in the SIMPLE_MID_SERVER folder, a "router.session" file is created.

On the SimpleOne instance

1. Create a new server record in the MID Server (sys_mid_server) table. To do so, click New and complete the fields of the new record as follows:

   Field	Description
   Name	TgBotMIDServer
   Host Name	A host name
   User	A user with the admin role

   
   

2. Create three scripts in the MID Scripts (sys_mid_script)table. To do so:
   1. In the MID Scripts (sys_mid_script)table, click New. A new Script form opens.
   2. Add   "createGroup" as the name of the script.

   3. Add the path to the script on your computer and the parameters, as shown below.

   4. 
      

      Repeat the Steps a-c to add "cancelGroup" and "deleteGroup" scripts.

      createGroup
      Script	C C:\User's Path\createGroup.py $botUserName $incidentDispalyName $titleMessage $mainInformation

      
      

      
      

      cancelGroup
      Script	C:\User's Path\cancelGroup.py $chatId

      
      

      deleteGroup
      Script	C:\User's Path\deleteGroup.py $chatId

      
      

3. Go to the System Properties (sys_property) table, set the following values for the properties:

   System Property	Value
   itsm.telegram_bot.swarming_session	true
   itsm.telegram_bot.mid_server_id	MID Server Record ID
   itsm.telegram_bot.mid_create_group_script_id	MID Scripts Record ID for a group creation (createGroup script)
   itsm.telegram_bot.mid_close_group_script_id	MID Scripts Record ID for comments restriction (cancelGroup script)
   itsm.telegram_bot.mid_delete_group_script_id:	MID Scripts Record ID for a group removal (deleteGroup script)

   
   

4. Go to a major incident form. Click the Start Swarming button on the top of the page. 
   
   

5. The modal window that appears, contains a list of the recipients of the invitation to the Telegram group. Clicking Start Swarming on the modal window initiates a Telegram group, and a createGroup record appears in the MID Queue (sys_mid_queue)table. The Description field of the createGroup record is automatically filled with the incident number.

   Field	Description
   Request	BotUserId, the incident name and the first message content that is sent to the Swarming Session participants
   Server	TgBotMIDServer.
   Script	The name of the executed script
   Response	A chat ID created and a lint to the group. The chat ID is stored in the Telegram Chat Bindings with Incident (sys_telegram_chat_bindings_with_incidents) table.
   State	Done when executed
   Processed at	Date and time of the script execution
   Description	Incident number

   If the connection with the Telegram bot is lost or failed, (see the ITSM Telegram Bot article for more information) a toast message "Telegram bot not connected" appears, and a modal window does not open.

   
   

6. When the incident state is changed to Completed,a closeGroup record in the MID Queue (sys_mid_queue) table appears. Since then, commenting in the group is unavailable, but the participants can read the messages.
   
   

   Field	Description
   Request	A chatId parameter
   Server	TgBotMIDServer
   Script	The name of the executed script
   Response	No response
   State	Done when executed
   Processed at	Date and time of the execution
   Description	Empty

   
   
   

7. When the incident state is changed to Closed,a deleteGroup record in the MID Queue (sys_mid_queue)table appears. The linked Telegram group is deleted.

   Field	Description
   Request	A chatId parameter
   Server	TgBotMIDServer
   Script	The name of the executed script
   Response	No response
   State	Done when executed
