Not able to link an epic to issue via rest api

I am able to create the issue successfully  but Epic Link which is a custom field is not set

api :

issue Post Data


{'fields': {'summary': 'summary', 'issuetype': {'self': '', 'id': '12200', 'description': '', 'name': 'Service Entitlement', 'subtask': False, 'avatarId': 17100}, 'customfield_17002': {'self': '', 'value': 'False', 'id': '18265'}, 'description': 'decription', 'project': {'self': '', 'id': '25400', 'key': 'TESTPREM3', 'name': 'Test Premium3 Premium Health check', 'customfield_16900': {'self': '', 'value': 'Premium 3.0', 'id': '18260'}, 'customfield_10903': 'TESTPREM3-126'}}

You should use Jira software API for it POST /rest/agile/1.0/epic/{epicIdOrKey}/issue. You can find more info here:

Thanks @Alexey Matveev _cPrime_ for sharing this, I am a bit surprised that setting the epic link is not supported via normal REST API (fields element updating custom field) as there is not much info about it based on the error here -

Hello @nik1989

What is the error you see in the response, is the issue created successfully but without the epic link?

@Tarun Saprayes , issue is created successfully , epic is not linked

Tarun Sapra Community Leader May 29, 2018

Is the epic link field available on the edit screen.

yes the epic link is available on edit screen.

Tarun Sapra Community Leader May 29, 2018

Strange, could you try doing it on the PUT request as shared by @Alexey Matveev _cPrime_ , thus once the issue is created then in the response you should have the issue key and then do a PUT request to update epic link.

tried that , but response is 404


url :

data: {'issues': ['TESTPREM3-133']}

Tarun Sapra Community Leader May 29, 2018

404 means - Returned if the epic does not exist or the user does not have permission to view it.

But that doesn't seem to be the case in your scenario as it's the same project. Your request was Put or POST?

The epic exists as i am able to see it on ui , i made a post request as the document says.

Tarun Sapra Community Leader May 29, 2018

What's your rest client, could you try the request with couple of different REST clients and see if the error is same, as it could be that you are running into a bug and might need to reach out to Atlassian support.

I am also getting same error 404.
my URL is

and data is :

"description":"Creating the jira for testing"

And I am using postman for raising the request


Please help me 

Thank You
