We have a custom built checkout which will use the normal tracking links with postback from the post-purchase Thank You page. Our cart has a promo code field which is currently populated by a cookie. I've created the coupon codes in PAP so they match the promo codes on our site, but I can't find a way to pass the coupon code to the cart either as a variable in the tracking link or by creating a custom cookie or editing the data in PAP's regular cookies.

Does anyone know of a way to send the coupon code data to the site? It seems crazy that a customer who clicks a referral link, still also has to manually enter the promo code to get the affiliate discount.

Hello Steve.

Your custom build cart can see if the URL contains an affiliate parameter or not. If it does, it can fill the promo code field for the user automatically.
Alternatively your cart could offer an option to send the promo code as it's own URL parameter. For example like this: &promo_code=1234 and when the visitor lands on your website with such parameter in his link your cart saves the field value in a cookie which will then populate the promo code field during the checkout automatically.

All this is cart functionality. It's not really related to our tracking software and it's tracking in any way.
