I want to do this, I want to test it, but Icant figure out how to hide the redirect page from other viewers. Any suggestions? With Auto Return turned on in your account profile, you can set the value of the return HTML variable on individual transactions, which overrides the value of the return URL that you stored on PayPal as part of the Auto Return feature. For example, you might want to redirect payers to a URL on your site that is specific to that person, perhaps with a session-id or other transaction-related data included in the URL.
To set the return URL for individual transactions, include the return variable in the HTML Form:
<INPUT TYPE="hidden" NAME="return" value="URLspecificToThisTransaction">
