DEPRECATED: Fitbit's support for OAuth 1.0a is deprecated and will no longer function as of April 12, 2016. You are encouraged to migrate to OAuth 2.0 and passport-fitbit-oauth2 as soon as possible.


Build Coverage Quality Dependencies

Passport strategy for authenticating with Fitbit using the OAuth 1.0a API.

This module lets you authenticate using Fitbit in your Node.js applications. By plugging into Passport, Fitbit authentication can be easily and unobtrusively integrated into any application or framework that supports Connect-style middleware, including Express.


$ npm install passport-fitbit


Create an Application

Before using passport-fitbit, you must register an application with Fitbit. If you have not already done so, a new application can be created at Fitbit Developers. Your application will be issued a consumer key and consumer secret, which need to be provided to the strategy. You will also need to configure a callback URL which matches the route in your application.

Configure Strategy

The Fitbit authentication strategy authenticates users using a Fitbit account and OAuth tokens. The consumer key and consumer secret obtained when creating an application are supplied as options when creating the strategy. The strategy also requires a verify callback, which receives the access token and corresponding secret as arguments, as well as profile which contains the authenticated user's Fitbit profile. The verify callback must call cb providing a user to complete authentication.

passport.use(new FitbitStrategy({
    consumerKey: FITBIT_CONSUMER_KEY,
    consumerSecret: FITBIT_CONSUMER_SECRET,
    callbackURL: ""
  function(token, tokenSecret, profile, cb) {
    User.findOrCreate({ fitbitId: }, function (err, user) {
      return cb(err, user);

Authenticate Requests

Use passport.authenticate(), specifying the 'fitbit' strategy, to authenticate requests.

For example, as route middleware in an Express application:


  passport.authenticate('fitbit', { failureRedirect: '/login' }),
  function(req, res) {
    // Successful authentication, redirect home.


Developers using the popular Express web framework can refer to an example as a starting point for their own web applications. The example shows how to authenticate users using Twitter. However, because both Twitter and Fitbit use OAuth 1.0, the code is similar. Simply replace references to Twitter with corresponding references to Fitbit.



The test suite is located in the test/ directory. All new features are expected to have corresponding test cases. Ensure that the complete test suite passes by executing:

$ make test


All new feature development is expected to have test coverage. Patches that increse test coverage are happily accepted. Coverage reports can be viewed by executing:

$ make test-cov
$ make view-cov
