Before using the SDK, set up your channels, categories, templates, and campaigns in the CometChat Dashboard. See the Dashboard Setup Guide for step-by-step instructions.
Key Concepts
How Cards Render in the Notification Feed
EachNotificationFeedItem has a content field containing an object — this is the Card Schema JSON. This JSON is passed directly to the CometChat Cards renderer library (@cometchat/cards-react).
The rendering flow:
- Fetch feed items via
NotificationFeedRequestBuilder - For each item, extract
item.getContent()— this is the Card Schema JSON - Convert to string:
JSON.stringify(item.getContent()) - Pass to the Cards renderer (
CometChatCardView) - The renderer produces a native DOM element from the JSON
Card Schema JSON Structure
body array contains elements (text, image, button, row, column, etc.) rendered top-to-bottom. Interactive elements like buttons emit actions via a callback — the consumer handles navigation, deep links, or API calls.
Retrieve Notification Feed Items
UseNotificationFeedRequestBuilder to fetch a paginated list of feed items. Uses cursor-based pagination internally.
Build the Request
- JavaScript
- TypeScript
Builder Parameters
Fetch Items
- JavaScript
- TypeScript
fetchNext() repeatedly for pagination. When the server has no more items, subsequent calls return an empty array.
NotificationFeedItem Fields
Retrieve Notification Categories
UseNotificationCategoriesRequestBuilder to fetch available categories for filter chips.
- JavaScript
- TypeScript
NotificationCategory Fields
Real-Time Notification Feed Listener
Listen for new feed items arriving via WebSocket. This listener is independent fromMessageListener, GroupListener, and CallListener.
- JavaScript
- TypeScript
Mark Feed Item as Read
Mark a single item as read. Idempotent — safe to call multiple times.- JavaScript
- TypeScript
Mark Feed Item as Delivered
Mark a single item as delivered. Idempotent.- JavaScript
- TypeScript
Mark Multiple Items as Delivered (Batch)
Report Engagement
Report that a user engaged with a feed item (e.g., viewed, clicked, interacted). Idempotent.- JavaScript
- TypeScript
interactionString parameter is a free-form string describing the engagement (e.g., "viewed", "clicked", "interacted").
Get Unread Count
Fetch the total number of unread notification feed items.- JavaScript
- TypeScript
Fetch Single Feed Item
Fetch a specific item by ID — useful for deep linking from push notifications.- JavaScript
- TypeScript
Push Notification Tracking
When a campaign push notification arrives via Web Push or FCM, use these methods to report delivery and click engagement.Mark Push Notification as Delivered
Call this when the push notification is received:- JavaScript
- TypeScript
Mark Push Notification as Clicked
Call this when the user taps the push notification:- JavaScript
- TypeScript

Rendering Cards
Thecontent field of each NotificationFeedItem is a Card Schema JSON object. To render it natively, use the CometChat Cards library.
Add the Cards Dependency
If you’re using
@cometchat/chat-uikit-react v6.5.0+, the cards library is included automatically as a dependency.Render a Card from a Feed Item
The Cards library is a pure renderer — it does not execute actions. Your code must handle action callbacks (opening URLs, navigating to chats, making API calls, etc.).
