Hey Madhuri,

This should work for you

curl -D- -u <username>:<password> -H "Content-Type:application/json" -X POST -d '{"user":["username"]}' -k

curl command.PNG

Using Node.js

//Use .defaults({strictSSL: false}) to by pass SSL certificate or https connection
var request = require('request').defaults({strictSSL: false})

var headers = {
    'Content-Type': 'application/json'

var dataString = '{"user":["cinguva","apawl"]}';

var options = {
    url: '',
    method: 'POST',
    headers: headers,
    body: dataString,
    auth: {
        'user': 'admin',
        'pass': 'password'


function callback(error, response, body) {


request(options, callback);

Hope this helps

The curl command worked for me for setting the project role. How would you unselect a role?

How can I get a list of project role ids in this case?

Hello, I have a scenario from my user . Situation is he wants around 100 users to be added to around 20 projects and assigned to multiple project roles. Can you suggest through curl example. From my end. we are not creating new groups due to our maintenance issues in jira. Without groups. is it possible through rest api from curl to achive this. Summarizinfg again. Adding m,ultople users to multiple project roles for around 20 projects. Please suggest/.
