Dear @Shal ,

User the REST endpoint: POST /rest/api/2/issueLink

The JSON data looks like this:

"type": {
"name": "Duplicate"
"inwardIssue": {
"key": "ABC-13"
"outwardIssue": {
"key": "ABC-7"

To get all possible link types use GET /rest/api/2/issueLinkType

So long


Thanks a lot @Thomas Deiler.

It's working. I was using PUT method instead of POST.

I want to update "Status" and "Resolution" field as well, is it possible with suggested JSON update and  REST endpoint: POST /rest/api/2/issueLink .

Or I have to do new HTTP request with new JSON  and REST endpoint.
