CJ not passing discount value

I just placed a test order, and the coupon code and discount were sent. In the plugin settings, if you check “Add debug info to order notes”, then it will tell you the URL that was used to send the order info to CJ. When a coupon code is used it should look something like this:

The following URL was used for the cj.com tracking code: https://www.emjcd.com/tags/c?containerTagId=xxx&ITEM1=test-2&AMT1=.25&QTY1=1&CID=xxx&OID=9490&TYPE=xxx&CJEVENT=&CURRENCY=USD&COUPON=coupon test&DISCOUNT=0.07

Can you ask CJ if this is still a valid way of sending the coupon discount info to them. It might be they changed how they expect the discount info to be sent to them.

Hi it is not working for me.

I tried to put the code like this:
CID=$cid&OID=$order_id&TYPE=$type&CJEVENT=$cjevent&CURRENCY=$currency&DISCOUNT=$discount_total

And it always return 0 like this:
The following URL was used for the cj.com tracking code: https://www.emjcd.com/tags/c?containerTagId=XXXX&ITEM1=XXXXX&AMT1=24.99&QTY1=1&CID=XXXXX&OID=XXXX&TYPE=XXXX&CJEVENT=&CURRENCY=USD&DISCOUNT=0&COUPON=hello10cj

and looking for more i checked that the units.php has this code:
function get_discount_total() {
$coupon_total = 0;
foreach($this->_coupons as $coupon){
$coupon_total += $coupon->amount();
}
return $coupon_total;
}

and it says 0

I don’t know what else to change to make it work
