Asked by fjavadpour:

hi, I'm new in crowd and node. I want to authenticate a user with crowd rest APIs.

i saw 'POST /rest/usermanagement/1/session' in the documentation but I don't know how to use it. should I install any packages like HTTP to use the crowd? anybody can help me here?

There is a dedicated NPM package for this: <https://www.npmjs.com/package/atlassian-crowd-client>

comments: author: fjavadpour
body: [@Bruno Vincent](/t5/user/viewprofilepage/user-id/853568) I still have some problems. here are some of my code. whats the problem? I get the below error

UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 2): Error: Application Permission Denied

and this is my codes:

var CrowdClient = require('atlassian-crowd-client');

var crowd = new CrowdClient({

baseUrl: '[http://myhost/crowd](http://account.tikab.org/crowd)',

application: { name: 'app-name', password: 'app-pass' } });

<br />

module.exports = {

show : function(req,res) {

crowd.session.create(('username', 'password'), (error, session) =\> {

You must add the IP address of the computer or server on which you're running that code to the list of authorized remote addresses for your application in Crowd's console: <https://confluence.atlassian.com/crowd/specifying-an-application-s-address-or-hostname-25788433.html>


author: fjavadpour
body: [@Bruno Vincent](/t5/user/viewprofilepage/user-id/853568), you mean that I should add localhost there? I'm getting a new error:

TypeError: validationFactors.toCrowd is not a function!!!

whats this for?


author: Bruno Vincent
body: You must add the IP address of the computer on which you're running the Node.js code. If Crowd and Node.js are installed on the same server/computer, yes 127.0.0.1 should work.

author: Bruno Vincent
body: ```
var CrowdClient = require('atlassian-crowd-client');

var User = require('atlassian-crowd-client/lib/models/user');

?

// Initialize the Crowd client:

var crowd = new CrowdClient({

        baseUrl: 'http://localhost:8095/crowd/',

        application: {

                name: 'test',

                password: 'password'

        }

});

?

// Authenticate to Crowd:

crowd.session.create('john.doe', 'password').then(function (session) {

    // Display Crowd SSO token 

        console.log('Crowd SSO token is ' + session.token);

    // Fetch the user profile:

    crowd.session.getUser(session.token).then(function (user) {

        console.log('Hello, ' + user.displayname);

tnx for your answer. and I have another question that is how can I get all users using rest API? i cant' understand it well


author: Bruno Vincent
body: In Node.js:

```
var CrowdClient = require('atlassian-crowd-client');

var User = require('atlassian-crowd-client/lib/models/user');

?

// Initialize the Crowd client:

var crowd = new CrowdClient({

        baseUrl: 'http://localhost:8095/crowd/',

        application: {

                name: 'test',

                password: 'password'

        }

});

?

// Find all users

crowd.search.user('').then(function (users) {

        console.log('Found ' + users.length + ' users:');

        users.forEach(function(username){

                console.log(username);

        });

});
```

With curl:

```
curl -X GET -u 'test:password' -H 'Accept: application/json' 'http://localhost:8095/crowd/rest/usermanagement/1/search?entity-type=user'
```

body: [@Bruno Vincent](/t5/user/viewprofilepage/user-id/853568) sorry that I ask a lot but I read Atlassian-crowd-client in npm website but I didn't see these methods like crowd.search or others. is there any link to find more info about this package usage?


author: Bruno Vincent
body: Hi [@fjavadpour](/t5/user/viewprofilepage/user-id/1208261)

I personally find the [documentation](https://www.npmjs.com/package/atlassian-crowd-client) pretty clear but if you want to know more about the package and the provided API I guess you should take a look at the [source code](https://github.com/ghengeveld/atlassian-crowd-client).


author: fjavadpour
body: [@Bruno Vincent](/t5/user/viewprofilepage/user-id/853568) and can you help me how to connect my crowd by the API? I saw **POST /rest/usermanagement/1/user** in the documentation but I don't know how should I use it. i'm using angular 5 by the way


author: Bruno Vincent
body: It depends on what you want to do. Crowd's REST API is fully explained and detailed here: <https://docs.atlassian.com/atlassian-crowd/3.1.3/REST/>


author: fjavadpour
body: [@Bruno Vincent](/t5/user/viewprofilepage/user-id/853568)assume that I want to add a user using angular 5 and node. I saw**POST /rest/usermanagement/1/user** in the documentation but howshould I use it in my HTTP services? I don't know what URL I should send a request to? what should the URL contain?

in my services I use :

**return http.post('URL').map(res =\> res.json()) ;**

but I don't know the correct URL for connecting crowd.


author: Bruno Vincent
body: The URI structure is explained in the first paragraph of Atlassian's documentation. Thus your URL should be something like:

```
http://localhost:8095/crowd/rest/usermanagement/1/user
```

But you should NOT request Crowd's REST endpoint with Javascript code running in your browser as this would require to embed your application's name and password within that code.

Call your Crowd server from the server side (Nodejs) using the NPM package we've already discussed. Adding a user is the very first example provided on the package's documentation page:

```
crowd.user.create(new User('John', 'Doe', 'John Doe', 'johndoe@example.com', 'johndoe', 'secret'));
```
