Must Trello Board be public to be accessible via api.trello?

I have been reviewing Trello api doc and in particular, the 3rd party, community projects looking for examples of retrieving boards for alternative display eventually into some digital signage. The board in question is private. The particular example is, python code. When executing trello.get_board(board_id) I get trello.Exceptions.Unauthorized: invalid key at If I copy the resolved url to a browser, I of course get the same error.

Hi Robert,


No, you can use the API to pull information from non-Public boards, that's not a problem. Your API calls need to include your correct API Key as well as an Oauth token to grant access to the board data.


More information on how that works is here:


If you still have questions about getting that working, feel free to reach out to us directly at and our developer advocate team can take a look!

Michael, thank you. I am working to figure out how to use the API through the Python wrapper. Knowing that if I am passing data correctly access to a private board works, answers my question.

I will reach out to your suggested contact if I am unable to get something working.
