scheduled push notifications api

If you mean an API for scheduled push notifications, here are the common approaches:

1. Send now via your push provider

Most push services let you send notifications immediately, e.g.:

• Firebase Cloud Messaging (FCM) for Android/web
• Apple APNs for iOS
• Third-party platforms like OneSignal, AWS SNS, Expo Push, etc.

2. Build scheduling yourself

Push providers usually don’t handle future scheduling natively in a simple way. Common pattern:

API flow

1. Your app calls your backend: POST /notifications/schedule
2. Backend stores:
   • title/body
   • target users/devices
   • send time
   • status = scheduled
3. A worker/cron job runs every minute (or queue delay system checks)
4. When time is reached, backend sends to FCM/APNs/OneSignal

Example request

{
  "userId": "123",
  "title": "Reminder",
  "body": "Your meeting starts in 10 minutes",
  "sendAt": "2026-10-14T15:30:00Z"
}

Example endpoints

• POST /notifications/schedule
• GET /notifications/:id
• DELETE /notifications/:id
• GET /notifications?status=scheduled

3. Use a job queue

For reliable scheduling, use:

• BullMQ / Redis
• Celery
• Sidekiq
• Cloud Tasks / Pub/Sub
• Quartz / Hangfire

This is better than plain cron if you need retries, delays, and scale.

Simple architecture

• API server: creates scheduled notifications
• DB: stores schedules
• Job worker: checks due notifications
• Push provider: delivers them

Important considerations

• Time zones and user-local time
• Retry logic for failures
• Idempotency to avoid duplicate sends
• Rate limits from push providers
• Cancelling/rescheduling notifications

If you want, I can help you with one of these:

1. Design the API spec
2. Write backend code for scheduling
3. Show FCM/APNs integration
4. Build a database schema for scheduled notifications
