After [integrating PayPal into Wufoo](/2007/06/18/proceed-to-checkout/), we got an overwhelming number of responses asking for more functionality and additional payment processors to be integrated into our platform. Based on this feedback, we’re happy to announce the addition of Google Checkout and [Authorize.net](http://reseller.authorize.net/application/?id=5558161) to Wufoo’s payment systems. We’ve also jazzed up our current PayPal integration by adding the ability to create recurring subscriptions.
###Google Checkout Integration
This was hands down the most highly requested feature addition to our payment system, and you’ll find that it’s probably the easiest way to hook up a form your Google Checkout account. To learn more about how to integrate your forms with Google Checkout, please check out our [Google Checkout Documentation](/docs/merchant/gcheckout/).
Authorize.net is a great alternative for those of you who need to process payments through your merchant account and cannot use services like Google Checkout or PayPal. This one tends to be for our non-profits and university institutions. It is a bit trickier to set up than the other two, but everything you need to know can be found in our [Authorize.net Documentation](/docs/merchant/authnet/).
###PayPal Recurring Subscriptions
With our new recurring payment settings through PayPal, you can now charge subscriptions fees that automatically bill your users on a periodic basis. This is great for monthly and yearly services that you’ve processed with Wufoo. Just check off the “Recurring Billing” box in your payment settings and then choose how often you’d like your customers to be billed.
