How to create task and sub-task at once via URL

[Alexander Li]

I need a button/url which creates task with mandatory fields which next automatically used to create sub-tasks bases on those fields

Button press > insert mandatory fields > in result we have task + subtasks

Hi @Alexander Li ,

I did not understand the idea of the button.

You want to add a button in one of your web pages like a widget ? Or are you trying to add this button as a transition ?

Are you on DC ? What version of Jira you are on ?

If you have automation on your Jira. Once you create your task, you can use automations to create your subtasks and copy fields from the parent issue.
