Commission through CJ

With a CJ publisher ID that Groupon confirmed on your storefront, every buyLink is CJ's click link around Groupon's checkout:

https://www.jdoqocy.com/click-<your publisher ID>-15230314?sid=<cartId>&url=<Groupon's checkout for the cart>

The shopper's browser passes through CJ, which records the click, and lands on the same checkout. Groupon reports the sale to CJ, and CJ credits it to your publisher account under its program terms, with the cart's id as the sale's SID in your CJ reports. Use the link exactly as the cart response gives it: a link you rebuild or shorten can lose the click, and with it the credit.

An ID you entered and Groupon has not confirmed yet, or one it refused, never reaches the link: until one is confirmed, buyLink is Groupon's checkout itself. GET /partner_storefront/me answers the confirmed ID in cjPublisherId, null without one. One CJ publisher ID credits one storefront.
