OneSignalSend Push Notification

Not everyone is going to remember all your important events, but that won't be a problem if you set up this Zapier automation. Once active, it will watch a specific Google Calendar for you, triggering a pre-set amount of time before every event starts. Whenever this happens, the event information will be sent to your audience in a OneSignal push notification, alerting everyone to get ready.

Note: This Zap will trigger 24 hours before an event is about to start by default, but that amount of time can be customized during setup.

How It Works

  1. A new event is about to start on Google Calendar
  2. Zapier sends out a push notification through OneSignal

What You Need

  • A Google Calendar account
  • A OneSignal account and the OneSignal SDK successfully set up on your site or app
