After you have purchased CouponPlugin.io Pro, downloaded it and installed it inside WordPress, you will need to activate it with the license you were granted with.
To find your license key, go to the email you were sent after making your purchase. Along with the download link you will see your license key.
To activate the license, copy the code and enter it in your WordPress admin panel under Coupons ->License
After entering the license, click on Save Changes.
If it has been accepted, a green “active” notice will be displayed and your plugin has been activated.
Once you have activated your license, you are good to go and can start creating your first coupon.
