Know available issuetypes that support subtask creation under them

[Naveenkumar Goudar]

JIRA APIs, is there a way to know list of issue-types which allow subtask creation under them..

API Get issue types for project though gives list of all issues-types and has flag indicating whether issuetype is a subtask or not, but we need to know if an issuetype supports subtask creation under that

Hey @nav ,

Welcome to Atlassian community!

Issue type/workitem type as subtask (hierarchy Level = -1) can be created for any of the standard issuetype/workitem type (hierarchyLevel = 0). When you use the API Get issue types for project in response if you get hierarchyLevel = 0, it means it will support subtask and it is standard issue type/workitem type.
