Mailchimp authentication strategy for Passport.


Passport strategy for authenticating with MailChimp using the OAuth 2.0 API.

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

The MailChimp authentication strategy authenticates users using a MailChimp account and OAuth 2.0 tokens. The strategy requires a verify callback, which accepts these credentials and calls done providing a user, as well as options specifying a app ID, app secret, and callback URL.

passport.use(new MailChimpStrategy({
    clientSecret: MAILCHIMP_APP_SECRET,
    callbackURL: "http://localhost:3000/auth/mailchimp/callback"
  }, function (accessToken, refreshToken, profile, done) {
    User.findOrCreate({ mailchimpId: }, function(err, user) {
      return done(err, user);

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

For example, as route middleware in an Express application:

app.get('/auth/mailchimp', passport.authenticate('mailchimp'));

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