title: Make a payment into someones paypal account using PHP
body: <p>I have a website where I need to reward users for their involvement by paying money into their paypal account. I have a paypal business account, and would like to know if it is possible to put money into their account automatically from just having their paypal account email address.</p>
  
  <p>I am developing my website using php. Ideally, I would like to have a script on my server that when executed transfers money from my business account into their paypal account.</p>
  
  <p>I am new to paypal, and having looked around I am getting confused as to all of the different APIs that are in use! MassPay keeps coming up but if possible I would rather I didnt have to pay the 2% charge on each payment - is there any other options?</p>
  
  <p>The payments are not for goods or services and so could be classed as a personal transfer, would this eliminate any fees?</p>
  
  <p>So my questions are:</p>
  
  <p>1) Is this possible?</p>
  
  <p>2) Which API is most suitable?</p>
  
  <p>Thanks</p>
