dr0832How do I make sure buyers that come to the Clickbank sales page do not access this other sales page?
Make sure that either your CB sales page has no links to any other page on your site, or that your other affiliate's sales page is not reachable via any links on other pages of your site.
dr0832I tried to set everything up. For some reason when I click on the order button it brings me to the E-junkie order page but there is no way to ckeck out. I see checkout: but it is greyed out. There is no checkout button on the order page. There is a continue shopping and update cart button which works fine.
Also I set the banner that I uploaded on the order page to the max size 736 x 90 but this only fills half the page and its left aligned. It looks pretty bad. Is there anyway to customize the order page in E-junkie to make it look more professional?
For ClickBank, you must use the Buy Now button code for ClickBank we provide. On your other affiliate's sales page, in your case we would recommend using your Buy Now button code for PayPal. Buy Now buttons will bypass our cart (the "E-junkie order page" you described) to take buyers directly to instant checkout with ClickBank or PayPal.
In order to use PayPal checkouts with E-junkie, click on Edit Profile in your Seller Admin and enter your PayPal Email where indicated, then click Submit to save changes. This must be either the email address you use to log into PayPal, or a secondary email added to that PayPal account. Once you do this, you will be able to obtain Buy Now button code for PayPal, and a PayPal checkout button should appear in your E-junkie shopping cart (if you use Cart buttons instead of Buy Now buttons).
dr0832Actually I just realized I had forgot to setup the Common Notification URL. The problem is I am already using this field in order to have E-junkie integrate with mail chimp.
The easiest way of solving that would be to put the PostAffiliatePro URL in your Common Notification URL, and then in your product settings, enable "Send transaction data to a URL" and click Next until you find the "Payment Variable Information URL" field, where you can paste your MailChimp integration URL, then click Next until you can Submit changes.
