Customizing Content Card behavior

This implementation guide discusses changing the behavior of Content Cards, adding extras such as key-value pairs to your payload, and recipes for common customizations.

Key-value pairs

Braze enables you to send extra data payloads via Content Cards to user devices using key-value pairs. These can help you track internal metrics, update app content, and customize properties. Add key-value pairs using the dashboard.

Key-value pairs are stored on card objects as extras. These can be used to send data down along with a card for further handling by the application. Call card.extras to access these values.

Content Cards as supplemental content

You can seamlessly blend Content Cards into an existing feed, allowing data from multiple feeds to load simultaneously. This creates a cohesive, harmonious experience with Braze Content Cards and existing feed content.

The example to the right shows a feed with a hybrid list of items that are populated via local data and Content Cards powered by Braze. With this, Content Cards can be indistinguishable alongside existing content.

API-triggered key-value pairs

API-triggered campaigns are a good strategy to employ when a card’s values depend on external factors to determine what content to display to the user. For example, to display supplemental content, set key-value pairs using Liquid. Note that class_type should be known at set-up time.

The key-value pairs for the supplemental Content Cards use case. In this example, different aspects of the card such as "tile_id", "tile_deeplink", and "tile_title" are set using Liquid.

Content Cards as interactive content

An interactive Content Card showing a 50 percent promotion appear in the bottom left corner of the screen. Once clicked, a promotion will be applied to the cart.

Content Cards can be leveraged to create dynamic and interactive experiences for your users. In the example to the right, we have a Content Card pop-up appear at checkout providing users last-minute promotions. Well-placed cards like this are a great way to give users a “nudge” toward specific user actions.

The key-value pairs for this use case include a discount_percentage set as the desired discount amount and class_type set as coupon_code. These key-value pairs allow you to filter and display type-specific Content Cards on the checkout screen. For more information on using key-value pairs to manage multiple feeds, see Customizing the default Content Card feed.

Content Card badges

Badges are small icons that are ideal for getting a user’s attention. Using badges to alert the user about new Content Card content can attract users back to your app and increase sessions.

Displaying the number of unread Content Cards as a badge

You can display the number of unread Content Cards your user has as a badge on your app’s icon.

You can request the number of unread cards at any time by calling:

1
Braze.getInstance(context).getContentCardUnviewedCount();
1
Braze.getInstance(context).contentCardUnviewedCount

You can then use this information to display a badge signifying how many unread Content Cards there are. See the SDK reference docs for more information.

The following sample uses braze.contentCards to request and display the number of unread Content Cards. Once the app is closed and the user’s session ends, this code requests a card count, filtering the number of cards based on the viewed property.

1
func applicationDidEnterBackground(_ application: UIApplication)

Within this method, implement the following code, which actively updates the badge count while the user views cards during a given session:

1
2
let unreadCards = AppDelegate.braze?.contentCards.cards.filter { $0.viewed == false }
UIApplication.shared.applicationIconBadgeNumber = unreadCards?.count ?? 0
1
(void)applicationDidEnterBackground:(UIApplication *)application

Within this method, implement the following code, which actively updates the badge count while the user views cards during a given session:

1
2
3
4
5
6
7
NSInteger unreadCardCount = 0;
for (BRZContentCardRaw *card in AppDelegate.braze.contentCards.cards) {
  if (card.viewed == NO) {
    unreadCardCount += 1;
  }
}
[UIApplication sharedApplication].applicationIconBadgeNumber = unreadCardCount;

You can request the number of unread cards at any time by calling:

1
braze.getCachedContentCards().getUnviewedCardCount();

You can then use this information to display a badge signifying how many unread Content Cards there are. See the SDK reference docs for more information.
