Passport-Dwolla

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

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

Install

$ npm install passport-dwolla

Usage

Configure Strategy

The Dwolla authentication strategy authenticates users using a Dwolla 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 client ID, client secret, and callback URL.

passport.use(new DwollaStrategy({
    clientID: DWOLLA_KEY,
    clientSecret: DWOLLA_SECRET,
    callbackURL: "http://127.0.0.1:3000/auth/dwolla/callback"
  },
  function(accessToken, refreshToken, profile, done) {
    User.findOrCreate({ dwollaId: profile.id }, function (err, user) {
      return done(err, user);
    });
  }
));

Authenticate Requests

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

For example, as route middleware in an Express application:

app.get('/auth/dwolla',
  passport.authenticate('dwolla', { scope: 'AccountInfoFull' }));

app.get('/auth/dwolla/callback', 
  passport.authenticate('dwolla', { failureRedirect: '/login' }),
  function(req, res) {
    // Successful authentication, redirect home.
    res.redirect('/');
  });

Examples

For a complete, working example, refer to the login example.
