Jira API to get details of all Sub-tasks

Question

Hi,

Are there any Jira APIs to get details of all sub-tasks in a project

I tried using JQL to fetch these details which i can see all sub-tasks are coming but when using it as a parameters in below URL, many sub-tasks are getting missed.

https://balic.atlassian.net/rest/api/2/search?jql

This is URL im using wherein i can see many sub-tasks are getting missed

https://balic.atlassian.net/rest/api/2/search?jql=%20project%20=%20OPS%20AND%20issuetype%20=%20%22Development%20Task%22%20order%20by%20created%20DESC

You are using the correct end-point, but please note that the response is paginated!

For example, if there are 10,000 sub-tasks on your issue, it will not return them as a single JSON response because that wouldn't scale. Instead, it returns the first batch of N issues, then gives you another link to return the second batch, and so on. You have to walk through all pages to get the full result.

Hi @Mayur Gaikwad/Tech PMO

Please check this doc about searching via rest api. Maybe this will help you to fix that - https://developer.atlassian.com/server/jira/platform/jira-rest-api-example-query-issues-6291606/

Another question - As I understand "Development Task" is your sub-task type right?

Hi @Mayur Gaikwad/Tech PMO

try the following JQL:

project = ProjectName and issuetype IN subTaskIssueTypes()

this displays all issues that are of type "subtask" in the project
