Hi all, I'm just developing generic alidator for IPNs ( curious can look at it in project on sourceforge: http://sourceforge.net/projects/jtec in module jtec-paypal ) I tried to follow code samples from pdf guides, but when I use posback URLs either from eliteweawer (http://www.eliteweaver.co.uk/testing/ipntest.php ) or from guide I get whole HTML document instead just a single word When I use just http://paypal.com/ everything workd fine though ( I get deserved INVALID ) Who is wrong, me or guide? Where do I postback when I'm in production? regards,
