# Notification APIs Overview

> Manage push, email, and SMS notification providers and preferences for your CometChat app.

The Notification APIs let you configure and manage notification delivery across push, email, and SMS channels. You can set up providers (FCM, APNS, SendGrid, Twilio), manage user preferences, and monitor notification logs.
