GoAffPro provides you with the option to disable the coupon code tracking.
To disable the coupon code tracking, go to the Affiliate Dashboard section in the Look and Feel tab of the GoAffPro admin panel.
Here, go to the Tracking Modes section.
Now, uncheck the "Coupon Code" option.
After this, the coupon code tracking will be disabled.
If the coupon code tracking is disabled, then the orders placed using an affiliate's coupon code will not get tracked.
The coupon code section will also get removed from the affiliate's account dashboard.
