Answer 1

Log into your PayPal account and use the button tool to create a saved button. the saved button replaces all of the sensitive data in the button code with a "Hosted button ID. here is an example of the hosted button code:

<form action="https://www.paypal.com/cgi-bin/webscr" method="post" target="_top">
<input type="hidden" name="cmd" value="_s-xclick">
<input type="hidden" name="hosted_button_id" value="L7NSNLBNU69AC">
