Update Issue label with JIRA REST API

[Uma Ilango]

Hi,

I would like to update my issue with new labels via JIRA REST API. I am using JIRA Server. 

Below is the curl used

curl --location --request PUT 'https://jiraserverurl/rest/api/latest/issue/PJFA-1' \

--header 'Content-Type: application/json' \

--header 'Authorization: Bearer XXXXX' \

--data-raw '{

    "update": {

        "labels": [

           {

               "add" : "newlabel"

           }

        ]

    }

}'

I am receiving 200 Http Status code. however, the labels are not added. Its always empty array
