I’ll introduce JavaScript sample code to mention User Group via Slack API.

Excerpt from Slack official documentation on how to mention User Group

For paid account there is an additional command for User Groups that follows the format <!subteam^ID|handle>. (subteam is literal text. ID and handle are replaced with the details of the group.) These indicate a User Group message, and should cause a notification to be displayed by the client. User Group IDs can be determined from the usergroups.list API endpoint. For example, if you have a User Group named happy-peeps with ID of S012345, then you would use the command <!subteam^S012345|happy-peeps> to mention that user group in a message.

So, if you want to mention the User Group @happy-peeps, write it as <!subteam^S012345|happy-peeps> and it will work correctly.

@user-group mention JavaScript sample code

The following is JavaScript sample code to mention User Group via Slack API:

var userGroup = ' ';
var slackMessage = userGroup + 'こんにちはこんにちは';

UrlFetchApp.fetch(
  'https://slack.com/api/chat.postMessage',
  {
    method: 'post',
    payload : {
      token: PropertiesService.getScriptProperties().getProperties().SLACK_TOKEN,
      channel: '#dev',
      username: 'bot',
      icon_emoji: ':robot_face:',
      text: slackMessage
    }
  }
);

I’m introducing partially modified code that was written for Google Apps Script.

That’s all from the Gemba where I want to mention User Group via Slack API as well.
