Pushy is a push notification API. Once you integrate one of our client SDKs in your app, you can start registering devices to receive push notifications by calling Pushy.register(). This method returns a unique device token that can be used to send push notifications to the device. Store this device token in your backend database.
When you're ready to start sending push notifications, your backend server simply needs to send a web request to our Send Notifications API with the device token(s) and push payload. Your app can then display a system notification or execute custom logic to handle the notification.
