I am an independent distributor of discount travel memberships. Now, from my site the customer can enroll and make payment but I have to link to another site and in order to get the credit they must put in my referral number. Is there a way I can somehow accept payment through the main site but have the information already entered? Or does anyone have an idea on how to make the payment checkout procedure better? Here is the enrollment page, you can see how it navigates from here.
Have you tried asking the main company support if you can pass the number through as a parameter in your string?
