Custom Variables
JVZoo
Last Update 2 months ago
Any custom variables that you put at the end of your link will show up in that field.
For example:
?mycustom=mine&myother=stillmine will give you those 2 sets of variable passed back through the JVZIPN from Paypal.
By using the cvendthru, you can pass a username of a user already created and you will find that value in the IPN payload.
