Clone JIRA Ticket using REST API?

[JJJ]

i want to clone issue project A to project B via JIRA REST API.

is there any solution directly use JIRA REST API?

if no solution, I'd like to try cloning in the way below.
please give me good opinions, thank you

<second solution>
1) all ticket search from project A (using rest/api/2/search)
2) create issue to project B (using above ticket list AND using rest/api/2/issue)

Hi @JJJ,

You can also try our Jira cloud app Deep Clone for Jira.

It's possible to bulk clone thousands of issues at once and move them to other projects or instances. With the Deep Clone REST API you can automate cloning issues with your scripts.

We offer many other advanced cloning features that might be helpful for you.

Hi,

There is no api to clone issue. You need to get the data of each issue

GET /rest/api/2/issue/{issueIdOrKey}

Then create a new issue in the project B.

POST /rest/api/2/issue
