Introducing Notifications

Notifications is our multi-channel delivery service. Send emails, SMS, push notifications, and webhooks through a single unified API.

What is Notifications?

Stop integrating with multiple providers. Notifications gives you one API to reach users on any channel.

Supported Channels

Email

Send transactional and marketing emails with templates and tracking.

import { Notifications } from '@fourbyfour/sdk';

const notifications = new Notifications({ apiKey: 'your-key' });

await notifications.send({
  channel: 'email',
  to: 'user@example.com',
  template: 'welcome',
  data: {
    name: 'John',
    activationLink: 'https://...'
  }
});

SMS

Send text messages globally with automatic carrier routing.

Push Notifications

Reach users on iOS, Android, and web with a single API call.

Webhooks

Notify external services when events happen in your application.

Smart Routing

Notifications automatically chooses the best provider based on:

• Delivery rates
• Cost
• Geographic location
• Channel availability

Delivery Tracking

Know exactly what happened to every notification:

• Sent
• Delivered
• Opened
• Clicked
• Bounced
• Failed

const status = await notifications.getStatus(notificationId);
console.log(status.delivered); // true
console.log(status.openedAt); // timestamp

Templates

Create templates once, use them across channels:

await notifications.createTemplate({
  id: 'order-confirmation',
  channels: ['email', 'sms', 'push'],
  content: {
    email: {
      subject: 'Order Confirmed',
      body: 'Your order {{orderId}} is confirmed.'
    },
    sms: 'Order {{orderId}} confirmed. Track: {{trackingUrl}}',
    push: {
      title: 'Order Confirmed',
      body: 'Your order is on its way!'
    }
  }
});
