title: Which payment method do I need to use for PHP PayPal API?
body: <p>I need to setup a payment method on my website that allows a certain user to pay another via two email address'. So essentially, user1 comes to a page, downloads an invoice and has the option to pay that invoice using a link which redirects to paypal with the prefilled details i.e. payeremail, receiveremail, amt, currencycode. Does anyone know which API call I need to make to do this? All I can really see in the API is for other users to pay my account which I already have setup for another function. Thanks in advance.</p>
