How do I schedule push notifications for later?

If you want to schedule push notifications for later, the usual approach is:

1. Store the notification request with a future send time.
2. Run a background job / scheduler at that time.
3. Send the push through your push provider then.

Common ways to do it

1) Use your backend + a job queue

Best for most apps.

• Save a record like:
  • user/device ID
  • message/title
  • scheduled time
  • delivery status
• Use a queue/scheduler such as:
  • Cron
  • Celery
  • Sidekiq
  • BullMQ
  • RQ
  • Quartz
  • Cloud Tasks / Pub/Sub / Lambda / EventBridge
• When the scheduled time arrives, your worker sends the push via:
  • Firebase Cloud Messaging (FCM)
  • Apple Push Notification service (APNs)
  • OneSignal, etc.

2) Use a push service that supports delayed sends

Some notification platforms support scheduling directly in their dashboard or API, e.g.:

• OneSignal
• Braze
• Airship
• Firebase + your backend scheduler

3) On-device scheduling

Usually not how push notifications are scheduled.

• Mobile OSs can schedule local notifications on the device.
• But push notifications are typically scheduled server-side because the server decides when to send them.

Important note

If you need the notification to be sent “later,” it must usually remain queued on your server until then. APNs/FCM generally don’t act as a long-term scheduler for you.

Example architecture

• User schedules notification for 3:00 PM
• Backend writes it to DB
• Worker polls due notifications every minute
• Worker sends push to FCM/APNs
• Mark as sent

If you want, I can show you:

• a Node.js example with BullMQ
• a Python/Celery example
• a Firebase/FCM scheduling setup
• or a database schema for scheduled notifications
