asana

Python client library for Asana.

Authentication

Personal Access Token

Create a client using your Asana Personal Access Token:

client = asana.Client.access_token('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:

client = asana.Client.oauth(
  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:

(url, state) = client.session.authorization_url()

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:

if request.params['state'] == state:
  token = client.session.fetch_token(code=request.params['code'])
  # ...
else:
  # error! possible CSRF attack

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:

me = client.users.me()
print "Hello " + me['name']

workspace_id = me['workspaces'][0]['id']
project = client.projects.create_in_workspace(workspace_id, { 'name': 'new project' })
print "Created project with id: " + project['id']

Methods that return multiple items (e.x. find_all) return a page 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:

# global:
asana.Client.DEFAULTS['page_size'] = 1000

# per-client:
client.options['page_size'] = 1000

# per-request:
client.tasks.find_all({ 'project': 1234 }, 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: 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 None.
• item_limit (default: None): limits the number of items of a collection to return.
• 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.get_next and events.get_iterator
• sync: sync token returned by previous calls to events.get (in response['sync'])

Collections

Items Iterator

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

workspaces = client.workspaces.find_all(item_limit=1)
print workspaces.next()
print workspaces.next() # raises StopIteration if there are no more items

Or:

for workspace in client.workspaces.find_all()
  print workspace

Raw API

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

offset = None
while True:
  page = client.workspaces.find_all(offset=offset, iterator_type=None)
  print page['data']
  if 'next_page' in 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.

Code generation

The specific Asana resource classes under gen (_Tag, _Workspace, _Task, etc) are generated code, hence they shouldn't be modified by hand. See the [asana-api-meta][meta] repo for details.

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. Edit package version in asana/version.py to indicate the semantic version change.
4. Commit the change
5. Tag the commit with v plus the same version number you set in the file. git tag v1.2.3
6. Push changes to origin, including tags: git push origin master --tags

Travis CI will automatically build and deploy the tagged release to pypi.
