JiraServer: https://confluence.atlassian.com/slack/atlassian-for-slack-integrations-967327515.html

I know that there is manual approach with:


But I am looking for some automated way with less handwork and more focus on the matter with the help of automation.

Is there any API for invoking in Listeners with Groovy lang?

At least, is there any way I can read docs about:

• com.atlassian.plugins.slack
• com.atlassian.jira.plugins.slack
  
  

in https://docs.atlassian.com/software/jira/docs/api/7.13.0/overview-summary.html  or any where else?

Those modules are mentioned in https://confluence.atlassian.com/slack/using-jira-applications-with-slack-966662163.html#UsingJiraapplicationswithSlack-SlashCommands
