AffiliateWP – Pushover Notifications GPL Overview:
Pushover is a service that allows you to receive push notifications on your iOS or Android-powered phone or tablet. This add-on for AffiliateWP gives your affiliates the option of connecting their phone or tablet via Pushover to your affiliate system, powered by AffiliateWP so that they receive push notifications anytime a new referral is awarded to their account.
Once the add-on is installed, a new tab will be added to your Affiliates → Settings screen called Pushover where you will be asked to enter your Pushover Application key, which can be retrieved from your Pushover account settings. Once your application key is entered, all affiliates will have a new field under their Settings tab of the Affiliate Area where they can enter their Pushover User Key.
