Asana PHP API

Official PHP client library for the Asana API v1

Installation

Composer

If you use Composer to manage dependencies you can include the "asana/asana" package as a depedency.

{
    "require": {
        "asana/asana": "^1.0.6"
    }
}

Alternatively you can specify the version as dev-master to get the latest master branch in GitHub.

Local

If you have downloaded this repository to the "php-asana" directory, for example, you can run composer install within "php-asana" then include the following lines at the top of a PHP file (in the same directory) to begin using it:

<?php
require 'php-asana/vendor/autoload.php';

Test

After running composer install run the tests using:

./vendor/bin/phpunit --configuration tests/phpunit.xml

You can also run the phpcs linter:

./vendor/bin/phpcs --standard=PSR2 --extensions=php src tests

Authentication

Personal Access Token

Create a client using a personal access token:

<?php
$client = Asana\Client::accessToken('ASANA_PERSONAL_ACCESS_TOKEN');

OAuth 2

Asana supports OAuth 2. asana handles some of the details of the OAuth flow for you.

Create a client using your OAuth Client ID and secret:

<?php
$client = Asana\Client::oauth(array(
    'client_id'     => 'ASANA_CLIENT_ID',
    'client_secret' => 'ASANA_CLIENT_SECRET',
    'redirect_uri'  => 'https://yourapp.com/auth/asana/callback',
));

Redirect the user to the authorization URL obtained from the client's session object:

<?php
$url = $client->dispatcher->authorizationUrl();

authorizationUrl takes an optional state parameter, passed by reference, which will be set to a random number if null, or passed through if not null:

<?php
$state = null;
$url = $client->dispatcher->authorizationUrl($state);
// $state will be a random number

Or:

<?php
$state = 'foo';
$url = $client->dispatcher->authorizationUrl($state);
// $state will still be foo

When the user is redirected back to your callback, check the state URL parameter matches, then pass the code parameter to obtain a bearer token:

<?php
if ($_GET['state'] == $state) {
  $token = $client->dispatcher->fetchToken($_GET['code']);
  // ...
} else {
  // error! possible CSRF attack
}

For webservers, it is common practice to store the state in a secure-only, http-only cookie so that it will automatically be sent by the browser in the callback.

Note: if you're writing a non-browser-based application (e.x. a command line tool) you can use the special redirect URI urn:ietf:wg:oauth:2.0:oob to prompt the user to copy and paste the code into the application.

Usage

The client's methods are divided into several resources: attachments, events, projects, stories, tags, tasks, teams, users, and workspaces.

Methods that return a single object return that object directly:

<?php
$me = $client->users->getUser("me");
echo "Hello " . $me->name;

$workspaceGid = $me->workspaces[0]->gid;
$project = $client->projects->createProjectForWorkspace($workspaceGid, array('name' => 'new project'));
echo "Created project with gid: " . $project->gid;

Methods that return multiple items (e.x. getTasks, getProjects, getPortfolios, etc.) return an items iterator by default. See the "Collections" section

Options

Various options can be set globally on the Client.DEFAULTS object, per-client on client.options, or per-request as additional named arguments. For example:

<?php
// global:
Asana\Client::$DEFAULTS['page_size'] = 1000;

// per-client:
$client->options['page_size'] = 1000;

// per-request:
$client->tasks->getTasks(array('project' => 1234), array('page_size' => 1000));

Available options

• base_url (default: "https://app.asana.com/api/1.0"): API endpoint base URL to connect to
• max_retries (default: 5): number to times to retry if API rate limit is reached or a server error occures. Rate limit retries delay until the rate limit expires, server errors exponentially backoff starting with a 1 second delay.
• full_payload (default: false): return the entire JSON response instead of the 'data' propery (default for collection methods and events.get)
• fields and expand: array of field names to include in the response, or sub-objects to expand in the response. For example array('fields' => array('followers', 'assignee')). See API documentation

Collections (methods returning an array as it's 'data' property):

• iterator_type (default: "items"): specifies which type of iterator (or not) to return. Valid values are "items" and null.
• item_limit (default: null): limits the total number of items of a collection to return (spanning multiple requests in the case of an iterator).
• page_size (default: 50): limits the number of items per page to fetch at a time.
• offset: offset token returned by previous calls to the same method (in response->next_page->offset)

Events:

• poll_interval (default: 5): polling interval for getting new events via events->getNext and events->getIterator
• sync: sync token returned by previous calls to events->get (in response->sync)

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. You can place it on the client for all requests, or place it on a single request.

$client = Asana\Client::accessToken('ASANA_PERSONAL_ACCESS_TOKEN', 
    array('headers' => array('asana-disable' => 'string_ids')))

or

$client = Asana\Client::accessToken('ASANA_PERSONAL_ACCESS_TOKEN', 
    array('headers' => array('asana-enable' => 'string_ids,new_sections')))

If you would rather suppress these warnings, you can set

$client = Asana\Client::accessToken('ASANA_PERSONAL_ACCESS_TOKEN', 
    array('log_asana_change_warnings' => false))

Collections

Items Iterator

By default, methods that return a collection of objects return an item iterator:

<?php
$workspaces = $client->workspaces->getWorkspaces();
foreach ($workspaces as $workspace) {
    var_dump($workspace);
}

Internally the iterator may make multiple HTTP requests, with the number of requested results per page being controlled by the page_size option.

Raw API

You can also use the raw API to fetch a page at a time:

<?php
$offset = null;
while (true) {
    $page = $client->workspaces->getWorkspaces(null, array('offset' => $offset, 'iterator_type' => null, 'page_size' => 2));
    var_dump($page);
    if (isset($page->next_page)) {
        $offset = $page->next_page->offset;
    } else {
        break;
    }
}

Contributing

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.

To develop:

• git clone [email protected]:Asana/php-asana.git
• composer install
• phpunit --configuration tests/phpunit.xml

Code generation

The specific Asana resource classes in the Gen folder (Tag, Workspace, Task, etc) are generated code, hence they shouldn't be modified by hand.

Deployment

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 in the VERSION file to indicate the semantic version change.
4. Update the README.md package depedency version in the "Installation" section
5. Commit the change.
6. Tag the commit with v plus the same version number you set in the file. git tag v1.2.3
7. Push changes to origin, including tags: git push origin master --tags
8. Log into packagist.org and click on the update button

The rest is automatically done by Composer / Packagist. Visit the asana package to verify the package was published.

NOTE: If the package did not update on Packagist, log into Packagist and click on the update button to manually update the package
