## What is ByN?

ByN — Build your Notification — is a push notification relay built for developers, DevOps engineers, and anyone who needs instant alerts from their infrastructure.
 
Create notification "listeners" in the app, then trigger them from anywhere with a simple HTTP request. No SDKs to integrate, no complex setup — just a curl command and your API key.
 
 HOW IT WORKS
 1. Sign in with a passwordless magic link — no passwords to remember.
 2. Create a notification listener with a custom title, body, priority, and icon.
 3. Copy your API key from Settings.
 4. Send a single HTTP POST to trigger a push notification to your phone.
 
 That's it. One API call, instant push notification.
 
 USE CASES
 • CI/CD Alerts — Get notified when builds finish, tests fail, or deployments complete.
 • Server Monitoring — Alert on high CPU, disk full, service down, or security events.
 • IoT & Smart Home — Receive sensor readings, door alerts, water level warnings, and temperature changes.
 • Cron Jobs & Scripts — Know immediately when scheduled tasks succeed or fail.
 • Home Automation — Connect to Home Assistant, Node-RED, or any system that can make HTTP requests.
 
 KEY FEATURES
 • Simple HTTP API — Trigger notifications with curl, Python, Node.js, or any language.
 • Passwordless Auth — Secure magic link login, no passwords to manage.
 • Multiple Listeners — Create separate notification channels for different use cases.
 • Notification History — See every notification sent, with timestamps and delivery status.
 • Priority Levels — Set normal or high priority for each listener.
 • Mute Control — Mute individual listeners per device without deleting them.
 • Multi-Device — Register multiple phones and tablets, all receive notifications.
 • API Key Management — View, copy, and regenerate your API key anytime.
 • Open & Lightweight — No vendor lock-in, no bloated SDKs.
 
 GETTING STARTED
 1. Download the app and sign in with your email.
 2. Create your first listener (e.g., "Server Alert").
 3. Go to Settings and copy your API key.
 4. From any terminal or script:
 
    curl -X POST https://api.buildyournotification.com/api/trigger \
      -H "X-API-Key: YOUR_KEY" \
      -H "Content-Type: application/json" \
      -d '{"listener_id": "YOUR_LISTENER_ID"}'
 
 5. Your phone buzzes. Done.
