Campaigns - CometChat Docs

CometChat Campaigns lets you deliver targeted, rich notifications to users via an in-app notification feed. Each notification is a Card Schema JSON — a structured layout rendered natively by the CometChat Cards library. The SDK provides APIs to fetch feed items, listen for real-time delivery, mark items as read/delivered, report engagement, and retrieve unread counts.

Key Concepts

Concept	Description
NotificationFeedItem	A single notification in the feed. Contains Card Schema JSON in its `content` field, a `category` for filtering, timestamps, and metadata.
NotificationCategory	A category label used for filter chips (e.g., “Promotions”, “Updates”).
Card Schema JSON	The fully rendered card layout (images, text, buttons) inside `NotificationFeedItem.getContent()`. Passed directly to the CometChat Cards renderer.
PushNotification	Represents a campaign push notification payload received via FCM/APNs or Web Push.

How Cards Render in the Notification Feed

Each NotificationFeedItem 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

{
  "version": "1.0",
  "body": [
    { "type": "image", "id": "img_1", "url": "https://...", "height": 200 },
    { "type": "text", "id": "txt_1", "content": "Flash Sale!", "variant": "heading2" },
    { "type": "button", "id": "btn_1", "label": "Shop Now", "action": { "type": "openUrl", "url": "https://..." } }
  ],
  "style": { "background": {"light": "#FFFFFF", "dark": "#1E1E1E"}, "borderRadius": 12, "padding": 16 },
  "fallbackText": "Flash Sale! Shop Now: https://..."
}

The 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

Use NotificationFeedRequestBuilder to fetch a paginated list of feed items. Uses cursor-based pagination internally.

Build the Request

JavaScript
TypeScript

const request = new CometChat.NotificationFeedRequestBuilder()
  .setLimit(20)
  .build();

const request: CometChat.NotificationFeedRequest = new CometChat.NotificationFeedRequestBuilder()
  .setLimit(20)
  .build();

Builder Parameters

Method	Type	Default	Description
`setLimit(limit)`	number	20	Items per page (max 100)
`setReadState(state)`	FeedReadState	`"all"`	Filter by `"read"`, `"unread"`, or `"all"`
`setCategory(category)`	string	null	Filter by category label
`setChannelId(channelId)`	string	null	Filter by channel
`setTags(tags)`	string[]	null	Filter by tags
`setDateFrom(date)`	string	null	ISO 8601 date — items sent on or after
`setDateTo(date)`	string	null	ISO 8601 date — items sent on or before

Fetch Items

JavaScript
TypeScript

request.fetchNext().then(
  (items) => {
    for (const item of items) {
      const cardJson = JSON.stringify(item.getContent());
      // Pass cardJson to CometChatCardView
    }
  },
  (error) => {
    console.error("Feed fetch error:", error.message);
  }
);

request.fetchNext().then(
  (items: CometChat.NotificationFeedItem[]) => {
    for (const item of items) {
      const cardJson: string = JSON.stringify(item.getContent());
      // Pass cardJson to CometChatCardView
    }
  },
  (error: CometChat.CometChatException) => {
    console.error("Feed fetch error:", error.message);
  }
);

Call fetchNext() repeatedly for pagination. When the server has no more items, subsequent calls return an empty array.

NotificationFeedItem Fields

Field	Type	Description
`getId()`	string	Unique item identifier
`getCategory()`	string	Notification category (e.g., “promotions”)
`getContent()`	object	Card Schema JSON — pass to CometChat Cards renderer
`getReadAt()`	number \| null	Unix timestamp when read, or null if unread
`getDeliveredAt()`	number \| null	Unix timestamp when delivered, or null
`getSentAt()`	number	Unix timestamp when sent
`getMetadata()`	`Record<string, any>`	Custom key-value metadata
`getTags()`	string[]	Tags for filtering
`getSender()`	string	Sender identifier
`getReceiver()`	string	Receiver identifier
`getReceiverType()`	string	Receiver type
`getIsRead()`	boolean	Whether the item has been read

Retrieve Notification Categories

Use NotificationCategoriesRequestBuilder to fetch available categories for filter chips.

JavaScript
TypeScript

const categoriesRequest = new CometChat.NotificationCategoriesRequestBuilder()
  .setLimit(50)
  .build();

categoriesRequest.fetchNext().then(
  (categories) => {
    for (const category of categories) {
      console.log("Category:", category.getLabel());
    }
  },
  (error) => {
    console.error("Categories fetch error:", error.message);
  }
);

const categoriesRequest: CometChat.NotificationCategoriesRequest =
  new CometChat.NotificationCategoriesRequestBuilder()
    .setLimit(50)
    .build();

categoriesRequest.fetchNext().then(
  (categories: CometChat.NotificationCategory[]) => {
    for (const category of categories) {
      console.log("Category:", category.getLabel());
    }
  },
  (error: CometChat.CometChatException) => {
    console.error("Categories fetch error:", error.message);
  }
);

NotificationCategory Fields

Field	Type	Description
`getId()`	string	Category identifier
`getLabel()`	string	Display name for filter UI

Real-Time Notification Feed Listener

Listen for new feed items arriving via WebSocket. This listener is independent from MessageListener, GroupListener, and CallListener.

JavaScript
TypeScript

CometChat.addNotificationFeedListener("feedListener", {
  onFeedItemReceived: (feedItem) => {
    console.log("New item:", feedItem.getId());
    const cardJson = JSON.stringify(feedItem.getContent());
    // Insert at top of feed and render
  },
});

CometChat.addNotificationFeedListener("feedListener", {
  onFeedItemReceived: (feedItem: CometChat.NotificationFeedItem) => {
    console.log("New item:", feedItem.getId());
    const cardJson: string = JSON.stringify(feedItem.getContent());
    // Insert at top of feed and render
  },
});

Remove the listener when no longer needed:

CometChat.removeNotificationFeedListener("feedListener");

Mark Feed Item as Read

Mark a single item as read. Idempotent — safe to call multiple times.

JavaScript
TypeScript

CometChat.markFeedItemAsRead(feedItem).then(
  () => { console.log("Marked as read"); },
  (error) => { console.error("Error:", error.message); }
);

CometChat.markFeedItemAsRead(feedItem).then(
  () => { console.log("Marked as read"); },
  (error: CometChat.CometChatException) => { console.error("Error:", error.message); }
);

Mark Feed Item as Delivered

Mark a single item as delivered. Idempotent.

JavaScript
TypeScript

CometChat.markFeedItemAsDelivered(feedItem).then(
  () => { /* Success */ },
  (error) => { console.error("Error:", error.message); }
);

CometChat.markFeedItemAsDelivered(feedItem).then(
  () => { /* Success */ },
  (error: CometChat.CometChatException) => { console.error("Error:", error.message); }
);

Mark Multiple Items as Delivered (Batch)

CometChat.markFeedItemsAsDelivered(feedItems).then(
  () => { /* Success */ },
  (error) => { console.error("Error:", error.message); }
);

Report Engagement

Report that a user engaged with a feed item (e.g., viewed, clicked, interacted). Idempotent.

JavaScript
TypeScript

CometChat.reportFeedEngagement(feedItem, "clicked").then(
  () => { /* Success */ },
  (error) => { console.error("Error:", error.message); }
);

CometChat.reportFeedEngagement(feedItem, "clicked").then(
  () => { /* Success */ },
  (error: CometChat.CometChatException) => { console.error("Error:", error.message); }
);

The 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

CometChat.getNotificationFeedUnreadCount().then(
  (result) => { console.log("Unread:", result.count); },
  (error) => { console.error("Error:", error.message); }
);

CometChat.getNotificationFeedUnreadCount().then(
  (result: { count: number }) => { console.log("Unread:", result.count); },
  (error: CometChat.CometChatException) => { console.error("Error:", error.message); }
);

Fetch Single Feed Item

Fetch a specific item by ID — useful for deep linking from push notifications.

JavaScript
TypeScript

CometChat.getNotificationFeedItem("item-id-123").then(
  (item) => {
    const cardJson = JSON.stringify(item.getContent());
    // Render the card
  },
  (error) => { console.error("Error:", error.message); }
);

CometChat.getNotificationFeedItem("item-id-123").then(
  (item: CometChat.NotificationFeedItem) => {
    const cardJson: string = JSON.stringify(item.getContent());
    // Render the card
  },
  (error: CometChat.CometChatException) => { console.error("Error:", error.message); }
);

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

const pushNotification = new CometChat.PushNotification(pushPayloadJson);

CometChat.markPushNotificationDelivered(pushNotification).then(
  () => { /* Success */ },
  (error) => { console.error("Error:", error.message); }
);

const pushNotification = new CometChat.PushNotification(pushPayloadJson);

CometChat.markPushNotificationDelivered(pushNotification).then(
  () => { /* Success */ },
  (error: CometChat.CometChatException) => { console.error("Error:", error.message); }
);

Mark Push Notification as Clicked

Call this when the user taps the push notification:

JavaScript
TypeScript

CometChat.markPushNotificationClicked(pushNotification).then(
  () => { /* Success */ },
  (error) => { console.error("Error:", error.message); }
);

CometChat.markPushNotificationClicked(pushNotification).then(
  () => { /* Success */ },
  (error: CometChat.CometChatException) => { console.error("Error:", error.message); }
);

PushNotification Fields

Field	Type	Description
`getId()`	string	Announcement ID from the push payload
`getAnnouncementId()`	string	Same as id (for clarity)
`getCampaignId()`	string \| null	Campaign ID if from a campaign
`getSource()`	string	Always `"campaign"` for notification feed pushes

FeedReadState

Value	Description
`"read"`	Only read items
`"unread"`	Only unread items
`"all"`	All items (default)

Rendering Cards

The content field of each NotificationFeedItem is a Card Schema JSON object. To render it natively, use the CometChat Cards library.

Add the Cards Dependency

npm install @cometchat/cards-react

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

import { CometChatCardView } from "@cometchat/cards-react";

function NotificationCard({ item }) {
  const cardJson = JSON.stringify(item.getContent());

  return (
    <CometChatCardView
      cardJson={cardJson}
      themeMode="auto"
      onAction={(event) => {
        const { action, elementId } = event;
        switch (action.type) {
          case "openUrl":
            // Open URL in browser
            window.open(action.url, "_blank");
            break;
          case "chatWithUser":
            // Navigate to chat with action.uid
            break;
          case "chatWithGroup":
            // Navigate to group chat with action.guid
            break;
        }
      }}
    />
  );
}

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.).

Supported Card Actions

When a user taps a button or link inside a card, the action callback receives one of these action types:

Action Type	Parameters	Description
`openUrl`	url, openIn	Open a URL in browser or webview
`chatWithUser`	uid	Navigate to 1:1 chat
`chatWithGroup`	guid	Navigate to group chat
`sendMessage`	text, receiverUid, receiverGuid	Send a text message
`copyToClipboard`	value	Copy text to clipboard
`downloadFile`	url, filename	Download a file
`initiateCall`	callType (audio/video), uid, guid	Start a call
`apiCall`	url, method, headers, body	Make an HTTP request
`customCallback`	callbackId, payload	App-specific logic
