After a transaction is successful for a product, buyers are redirected to that product thank you page. ClickBetter provides you option to send customer details to that page either by HTTP POST or HTTP GET (appended to URL).
To do this, log in to your ClickBetter.com account, and click on My Products menu. Under settings tab on sell page, you will see an option that says "Send To URL". Right below it, you would be able to set it as HTTP "GET OR POST".
Following parameters are sent to your thank you page URL once you set the above:
"orderid" - ClickBetter unique Order ID of the purchase
"affiliate" - ClickBetter username of affiliate if any
"customeremail" - Email of the customer provided during the checkout
"pid" - ClickBetter.com product ID
