I am creating a jira ticket using the REST api with a payload given below

        "fields": {
        "project": {
            "key": "TP"
        "summary": "Sample issue created via Curl",
        "description": "This is a test issue created using the Jira Curl command",
        "issuetype": {
            "name": "Task"
        "assignee": {
            "name": "kanwar.robinson"

but the ticket is sucessfully created but the assignee in the ticket is unassigned

but i am able to do the assigning while creation in UI itself

can anyone tell if i am missing any permissions or something else??

Hi @kanwarrobinson_salethraja ,

Welcome to the Community.

The way you're using your REST endpoint to assign a user with the display name is used on the On-premises.

As you are using Cloud, you need to pass the assignee id or account Id with the following format



instead of   

"assignee": {"name": "kanwar.robinson"}


PS: You can get the Assignee Id when checking the User's profile.


Additionally, you can achieve this and access to more REST services by using a 3rd Party App, like Power Scripts that can be really helpful to automate your workflows.


I hope it helps.

Thank you.

Hello @kanwarrobinson_salethraja 

Please pass the accountID instead of name like below:

"assignee": { "id": "5b109f2e9729b51b54dc274d" }

Also, tickets gets assigned to Project Lead if you are not passing a default value, so maybe check the Jira project configuration as well.
