The OneSignal plugin for Bubble allows developers to send personalized or mass notifications to their users, making it easier to engage with customers smarter, not harder. This plugin enables features such as re-engaging interested customers, instant messaging while offline, and announcing big changes to the user base. With this plugin, developers can bring their app directly to their users by installing it in the Plugins tab and easily send out notifications through the OneSignal dashboard or Bubble's Scheduled API Workflow. The plugin is designed to make sending push notifications more streamlined than ever before.
