Hi Larry,
The connection of return pages (cancel.php and thank.php) must be secure (using https connection) ?
The ipn.php need secure https connection ?
If cancel.php, thank.php and ipn.php need secure connection, my web hosting must got SSL ?
I ask because when I configured paypal integrate payment on paypal sandbox site, I saw the return
page textfields example show ( https://www.example.com/cancel.php
or https://www.example.com/thank.php )
Thanks for reply
