The documentation states: and both [PayPal REST API](https://developer.paypal.com/docs/api-basics/), [PayPal Express (NVP)](https://developer.paypal.com/docs/nvp-soap-api/) and [PayPal Payflow Pro](https://merchant.paypal.com/us/cgi-bin/?cmd=_render-content&content_ID=merchant/payment_gateway). But there is no real support for the REST API i.e. using PayPal's Javascript SDK. Also, the word "both" doesn't match the content (3 items, not 2). Could you clarify and/or rectify?
