Python API wrapper around Trello's API
Latest commit 93d8110 @sarumont Merge pull request #116 from Sveder/master
A few things I added for a project of mine:


A wrapper around the Trello API written in Python. Each Trello object is represented by a corresponding Python object. The attributes of these objects are cached, but the child objects are not. This can possibly be improved when the API allows for notification subscriptions; this would allow caching (assuming a connection was available to invalidate the cache as appropriate).

I've created a Trello Board for feature requests, discussion and some development tracking.


pip install py-trello


from trello import TrelloClient

client = TrelloClient(
api_key='your-key', api_secret='your-secret', token='your-oauth-token-key', token_secret='your-oauth-token-secret'


Where token and token_secret come from the 3-legged OAuth process and api_key and api_secret are your Trello API credentials that are (generated here).

Getting your Trello OAuth Token

Make sure the following environment variables are set:


These are obtained from the link mentioned above.

TRELLO_EXPIRATION is optional. Set it to a string such as 'never' or '1day'. Trello's default OAuth Token expiration is 30 days.

Default permissions are read/write.

More info on setting the expiration here:

python ./trello/

Required Python modules

Found in requirements.txt


To run the tests, run python Three environment variables must be set:

  • TRELLO_API_KEY: your Trello API key
  • TRELLO_TOKEN: your Trello OAuth token
  • TRELLO_TEST_BOARD_COUNT: the number of boards in your Trello account
  • TRELLO_TEST_BOARD_NAME: name of the board to test card manipulation on. Must be unique, or the first match will be used

And run (from py-trello/):

PYTHONPATH=. python test/
