NotificationAPI
NotificationAPI eliminates most of the notification-related tasks in your backlog. It saves precious development time and empowers your non-technical team (designers, customer success, marketing) to directly build and maintain notifications. NotificationAPI's dashboard allows product teams to configure and design notifications to any channel (email, SMS, push, ...) while developers can use our SDKs to trigger sending these notifications from their software with a few lines of code. NotificationAPI can be thought of as a Notification-as-a-Service.
