To name your coupon, go to:
Site/Courses > Coupons > Create Coupon
In Zenler, you have the ability to name your coupon, which will serve as an identifier for you and can be handy for monitoring your different coupons within your Zenler site.
It's recommended that you add a 'Description' for all the coupons you create on your site to make them easier to manage.
