Easy integration with Chargify for adding recurring payments to your application.

This library inspired, and has been superceded by Fermata. While Fermata's API is a little different, the codebase descends more or less directly from this library, so the overall idea is very similar.

The main differences are improved callback arguments (an error is now provided for bad status codes) and the removal of the .add, .remove and .req methods in favor of a generic HTTP method call syntax.

Oh, and also! Under node.js (and some browsers, not that that's relevant for this plugin), Fermata behaves as catch-all Proxy object. So in many cases you can actually drop the parentheses and treat the REST URLs native objects: site.subscriptions[42].components[5].get(callback)

Other than that, you should find the new library quite familiar once you load the Chargify plugin (included):

var f = require('fermata'),
    c = require('fermata/plugins/chargify');
f.registerPlugin('chargify', c);

var wrapped_site = f.chargify('example-site', "API_KEY"),
    some_subscription = wrapped_site('subscriptions')(42);  // or even `wrapped_site.subscriptions[42]`!
some_subscription.get(function(err, data) { if (!err) console.log(data.subscription.state); });

By using Fermata you get the benefits of a more refined version of this API, in a library useable with Chargify and any other RESTful services your app needs to connect to.

(end of Important Note), this here library's API documentation below…

As of version 0.2, this module is essentially a wrapper around Request, but adds a little convenience for connecting to the Chargify API.

You can normally require and instantiate at the same time using your Chargify subdomain and API key.

var chargify = require('chargify');
var chargify_site = chargify('YOUR-CHARGIFY-SUBDOMAIN', 'YOUR-API-KEY');

List subscriptions:

chargify_site.get('subscriptions.json', function(err, res, body) {
    if (err) throw err;
    console.log(res.statusCode);
    console.log(body);
});

Load subscription #40:

chargify_site.get('subscriptions/40.json', function(err, res, body) {
    if (err) throw err;
    console.log(res.statusCode);
    console.log(body);
});

Create a new customer:

chargify_site.post({
    pathname: 'customers.json',
    json: {
        customer: {
            first_name: 'Joe',
            last_name: 'Blow',
            email: '[email protected]'
        }
    }
}, function(err, res, body) {
    if (err) throw err;
    console.log(res.statusCode);
    console.log(body);
});

Returns a chargify_site. The available methods are listed below.

• chargify_site.get(options, callback)
• chargify_site.post(options, callback)
• chargify_site.put(options, callback)
• chargify_site.del(options, callback)

The first argument can be either a url or an options object. he only required key is uri. The only required option is uri, all others are optional. The key attributes are listed below. See the Request module's README for a full list.

• uri - Required. The URI of the resource. host, protocol, and auth information are optional.
• json - sets the body of the request using a JavaScript object.

• Request documentation
• Chargify API documentation

Before running the tests, you need to create a Chargify test site and specify the site's subdomain and your API key in a JSON file called config.json.

Example config.json file:

{
    "chargifySubdomain": "chargify-test",
    "chargifyAPIKey": "xxxxxxxxxxxxxx-9x_"
}

Then simply run:

npm test
