API REST - How to get subtask list of an issue

[Vaclav Jezek]

I need to get list of all subtasks for one given issue. I am using API REST. Is it possible?

Actually I forgot about one more, simpler solution - use jql (also with /rest/api/2/search): parent = your-issue-key

Hi! I have a question related from above but I'm using the SDK. I would like to get the Sub-tasks from every issue with a certain project.. Here is my code snippet

var issueList = jira.Issues.Where(x=>x.Project == "MYSAMPLEPROJECT");
foreach (var issueItem in issueList)
{
   /*Get the sub-tasks collection of the issue*/ 
}

Thank you very much!

Yes it is possible. Use /rest/api/2/search with jql like that: issueKey = your-key AND issuetype in (all-subtask-types-here)
