What about triggering your builds once you get an update from the Development Team on Slack and from their itself you triggered the job, so that all the needful can be done and reports added in your job configuration can be mailed back to developers!!!
So here we go :
Here you will make the entry in the URL mentioning your https://jenkins-user:token_no@jenkins_url/job/job_name/build?token=token_name
And at last, you can add an Autocomplete help task which helps you to find your added command easily while triggering, Click save. Go back to Slack and try run your command with the given name and your build will be triggered.
Hope You gonna try and make your builds easy to trigger. Keep Building
