[Passport](http://passportjs.org/) strategy for authenticating with Instagram access tokens using the OAuth 2.0 API.

This module lets you authenticate using Instagram in your Node.js applications.
By plugging into Passport, Instagram authentication can be easily and unobtrusively integrated into any application or framework that supports [Connect](http://www.senchalabs.org/connect/)-style middleware, including [Express](http://expressjs.com/).

## Installation

```shell
npm install @mpassante/passport-instagram-token-2
```

## Usage

### Configure Strategy

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

```javascript
var InstagramTokenStrategy = require('passport-instagram-token');

passport.use(new InstagramTokenStrategy({
    clientID: INSTAGRAM_CLIENT_ID,
    clientSecret: INSTAGRAM_CLIENT_SECRET,
    passReqToCallback: true
}, function(req, accessToken, refreshToken, profile, next) {
    User.findOrCreate({'instagram.id': profile.id}, function(error, user) {
        return next(error, user);
    });
}));
```

### Authenticate Requests

Use `passport.authenticate()`, specifying the `instagram-token` strategy, to authenticate requests.

For example, as route middleware in an [Express](http://expressjs.com/) application:

```javascript
app.get('/auth/instagram', passport.authenticate('instagram-token'));
```

Or if you are using Sails framework:

```javascript
// AuthController.js
module.exports = {
    instagram: function(req, res) {
        passport.authenticate('instagram-token', function(error, user, info) {
            if (error) return res.serverError(error);
            if (info) return res.unauthorized(info);
            return res.ok(user);
        })(req, res);
    }
};
```

The request to this route should include a GET or POST data with the keys `access_token` and optionally, `refresh_token` set to the credentials you receive from Instagram.

```
GET /auth/instagram?access_token=<TOKEN>
```

## Issues

If you receive a `401 Unauthorized` error, it is most likely because you have wrong access token or not yet specified any application permissions.
Once you refresh access token with new permissions, try to send this access token again.
