Asana GitHub release Build Status NPM Version

A JavaScript client (for both Node and browser) for the Asana API v1.0.



Install with npm:

npm install asana --save


Include the latest release directly from GitHub.

<script src="<LATEST_RELEASE>/asana-min.js"></script>


  1. Download the latest distribution in releases.
  2. Make sure to serve it from your webserver.
  3. Include it on the client from a SCRIPT tag.

Design Decisions

  • Thin Wrapper This client is a thin wrapper which means that the client makes little attempt to verify the validity of the arguments locally. All errors are reported by the server. We include custom Error types which will contain the response from the server.
  • Promises Promises with bluebird seem like the most neutral way to support node's various async paradigms. If you want promises, you get them by default. If you want callbacks, bluebird promises support nodeify which takes a callback as parameter. For generators and streams, co and highland also support promises respectively. Beyond that, other major libraries such as mongoose, mocha, and elastic search (which uses bluebird) also support promises.


To do anything, you'll need always an instance of an Asana.Client configured with your preferred authentication method (see the Authentication section below for more complex scenarios) and other options.

The most minimal example would be as follows:

const asana = require('asana');
const client = asana.Client.create().useAccessToken('my_access_token'); {

All resources are exposed as properties of the Asana.Client instance (e.g. client.workspaces). See the developer documentation for docs on each of them.


This module supports authenticating against the Asana API with either a Personal Access Token or through OAuth 2.0.

Personal Access Token

const client = Asana.Client.create().useAccessToken('personal_access_token');

OAuth 2.0

Authenticating through OAuth2 is preferred. There are many ways you can do this.

In all cases, you should create a Client that contains your app information. The values in the below snippet should be substituted with the real properties from your application's settings.

const client = Asana.Client.create({
  clientId: 123,
  clientSecret: 'my_client_secret',
  redirectUri: 'my_redirect_uri'
With a plain bearer token (doesn't support auto-refresh)

If you have a plain bearer token obtained somewhere else and you don't mind not having your token auto-refresh, you can authenticate with it as follows:

  credentials: 'my_access_token'
With a refresh token

If you obtained a refresh token (from a previous authorization), you can use it together with your client credentials to authenticate:

const credentials = {
  // access_token: 'my_access_token',
  refresh_token: 'my_refresh_token'
  credentials: credentials

See examples/oauth/webserver for a working example of this.


Whenever you ask for a collection of resources, you will receive a Collection object which gives you access to a page of results at a time. You can provide a number of results per page to fetch, between 1 and 100. If you don't provide any, it defaults to 50.

client.tasks.findByTag(tagId, { limit: 5 }).then(function(collection) {
  // [ .. array of up to 5 task objects .. ]

Additionally, Collection has a few useful methods that can make them more convenient to deal with.

Individual page iteration

To get the next page of a collection, you do not have to manually construct the next request. The nextPage method takes care of this for you:

client.tasks.findByTag(tagId).then(firstPage => {
  firstPage.nextPage().then(secondPage => {

Automatic page iteration

To automatically fetch a bunch of results and have the client transparently request pages under the hood, use the fetch method.:

client.tasks.findByTag(tagId).then(collection => {
  // Fetch up to 200 tasks, using multiple pages if necessary
  collection.fetch(200).then(tasks => {


You can also construct a stream from a collection. This will transparently (and lazily) fetch the items in the collection in pages as you iterate through them.

client.tasks.findByTag(tagId).then(collection => {'data', task => {

Error handling

In any request against the Asana API, there a number of errors that could arise. Those are well documented in the Asana API Documentation, and are represented as exceptions under the namespace Asana.errors.


To add global headers (like for our deprecation framework), you add them to the client.

asana.Client.create({"defaultHeaders": {"asana-enable": "string_ids,new_sections"}});

Asana Change Warnings

You will receive warning logs if performing requests that may be affected by a deprecation. The warning contains a link that explains the deprecation.

If you receive one of these warnings, you should:

  • Read about the deprecation.
  • Resolve sections of your code that would be affected by the deprecation.
  • Add the deprecation flag to your "asana-enable" header.

If you would rather suppress these warnings, you can set

asana.Client.create({"logAsanaChangeWarnings": false});


Various examples are in the repository under examples/, but some basic concepts are illustrated here.

Find some incomplete tasks assigned to me that are new or marked for today in my default workspace

const Asana = require('asana');
const util = require('util');

// Using a PAT for basic authentication. This is reasonable to get
// started with, but Oauth is more secure and provides more features.

var client = Asana.Client.create().useAccessToken(process.env.ASANA_PAT);
  .then(user => {
    const userId =;
    // The user's "default" workspace is the first one in the list, though
    // any user can have multiple workspaces so you can't always assume this
    // is the one you want to work with.
    const workspaceId = user.workspaces[0].id;
    return client.tasks.findAll({
      assignee: userId,
      workspace: workspaceId,
      completed_since: 'now',
      opt_fields: 'id,name,assignee_status,completed'
  .then(response => {
    // There may be more pages of data, we could stream or return a promise
    // to request those here - for now, let's just return the first page
    // of items.
  .filter(task => {
    return task.assignee_status === 'today' ||
      task.assignee_status === 'new';
  .then(list => {
    console.log(util.inspect(list, {
      colors: true,
      depth: null
  .catch(e => {


The code is thoroughly documented with JsDoc tags. The Official Asana Documentation is a great resource since this is just a thin wrapper for the API.


Feel free to fork and submit pull requests for the code! Please follow the existing code as an example of style and make sure that all your code passes lint and tests. For a sanity check:

git clone
cd node-asana
npm install
npm test

Code generation

The specific Asana resource classes (Tag, Workspace, Task, etc) are generated code, hence they shouldn't be modified by hand. See the asana-api-meta repo for details.


Repo Owners Only. Take the following steps to issue a new release of the library.

  1. Merge in the desired changes into the master branch and commit them.
  2. Clone the repo, work on master.
  3. Bump the package version to indicate the semantic version change, using one of: gulp bump-patch, gulp bump-feature, or gulp bump-release
  4. Push changes to origin, including tags: git push origin master --tags

Travis CI will automatically build and deploy the tagged release.

You can’t perform that action at this time.
