Done a site which take recurring payments with paypal using a credit card. I now want to offer the user to the ability to use a paypal account to pay. I followed a guide and https://cms.paypal.com/uk/cgi-bin/?cmd=_render-content&content_ID=developer/e_howto_api_WPRecurringPayments
However paypal have updated their express checkout api so i cant find documentation which follows the api. I am wondering if some one has more up to date documentation on which fields i need to pass to paypal.
Best Regards
