How to authenticate Fitbit user with OAuth 2.0?

Question

I am trying to write a web application with Python using the Fitbit API. I need to authenticate the user with OAuth 2.0 in the browser. Right now I'm trying to use python-fitbit , though I'm not sure there's a better way to do this. Here is my code:

import fitbit
client = fitbit.FitbitOauth2Client('client_id', 'client_secret')
res = client.make_request("https://api.fitbit.com/1/user/-/activities.json", None, method='GET')

When I run it, I get ValueError: Missing access token. What am I doing wrong here? I feel totally in over my head with this.

Answer 1

Did you notice this known bug in python-fitbit?

https://github.com/orcasgit/python-fitbit/issues/70

Seems like it might be what you're hitting. That user described a workaround in using another fitbit python client.

Edit: Adding quote from other article for a better answer!

As I successfully obtain my token using another Fitbit API client ( https://github.com/magnific0/FitBit.py ), it seems there is a problem with your script "gather_keys_oauth2.py".

I would say that oauthlib call using OAuth2Session should not try to validate the token during the request phase.

Answer 2

Looks like the issue was fixed in the code ( gather_keys_oauth2.py ) a week or so ago, but I couldn't find the documentation how to use the fixed code.

Looking for simple example if possible.

@orcasgit/orcas-developers Please review. This should get the OAuth2 authentication working again. Works in my testing.
