Tarjetas de contenido

Prerequisites

Before you can use Content Cards, you’ll need to integrate the Braze Web SDK into your app. However, no additional setup is required. To build your own UI instead, see Content Card Customization Guide.

Standard feed UI

To use the included Content Cards UI, you’ll need to specify where to show the feed on your website.

In this example, we have a <div id="feed"></div> in which we want to place the Content Cards feed. We’ll use three buttons to hide, show, or toggle (hide or show based on its current state) the feed.

<button id="toggle" type="button">Toggle Cards Feed</button>
<button id="hide" type="button">Hide Cards Feed</button>
<button id="show" type="button">Show Cards Feed</button>

<nav>
    <h1>Your Personalized Feed</h1>
    <div id="feed"></div>
</nav>

<script> 
   const toggle = document.getElementById("toggle");
   const hide = document.getElementById("hide");
   const show = document.getElementById("show");
   const feed = document.getElementById("feed");
    
   toggle.onclick = function(){
      braze.toggleContentCards(feed);    
   }
    
   hide.onclick = function(){
      braze.hideContentCards();
   }
    
   show.onclick = function(){
      braze.showContentCards(feed);    
   }
</script>

When using the toggleContentCards(parentNode, filterFunction) and showContentCards(parentNode, filterFunction) methods, if no arguments are provided, all Content Cards will be shown in a fixed-position sidebar on the right-hand side of the page. Otherwise, the feed will be placed in the specified parentNode option.

See the SDK reference docs for more information on Content Card toggling.

Card types and properties

The Content Cards data model is available in the Web SDK and offers the following Content Card types: ImageOnly, CaptionedImage, and ClassicCard. Each type inherits common properties from a base model Card and has the following additional properties.

Base card model

All Content Cards have these shared properties:

Image only

ImageOnly cards are clickable full-sized images.

Captioned image

CaptionedImage cards are clickable, full-sized images with accompanying descriptive text.

Classic

The ClassicCard model can contain an image with no text or a text with image.

Control group

If you use the default Content Cards feed, impressions and clicks will be automatically tracked.

If you use a custom integration for Content Cards, you need need log impressions when a Control Card would have been seen. As part of this effort, make sure to handle Control cards when logging impressions in an A/B test. These cards are blank, and while they aren’t seen by users, you should still log impressions in order to compare how they perform against non-Control cards.

To determine if a Content Card is in the Control group for an A/B test, check the card.isControl property (Web SDK v4.5.0+) or check if the card is a ControlCard instance (card instanceof braze.ControlCard).

Using Google Tag Manager

Google Tag Manager works by injecting the Braze CDN (a version of our Web SDK) directly into your website code, which means that all SDK methods are available just as if you had integrated the SDK without Google Tag Manager, except when implementing Content Cards.

Setting up Content Cards

• google tag manager
• manual

Upgrading templates

To upgrade to the latest version of the Braze Web SDK, take the following three steps in your Google Tag Manager dashboard:

1. Update tag template
   Go to the Templates page within your workspace. Here you should see an icon indicating an update is available.
   
   
   
   Click that icon and after reviewing the change, click to Accept Update.
   
   
   
   
2. Update version number
   Once your tag template has been updated, edit the Braze Initialization Tag, and update the SDK version to the most recent major.minor version. For example, if the latest version is 4.1.2, enter 4.1. You can view a list of SDK versions in our changelog.
   
   
   
   
3. QA and publish
   Verify the new SDK version is working using Google Tag Manager’s debugging tool prior to publishing an update to your tag container.

Troubleshooting

Enable tag debugging

Each Braze tag template has an optional GTM Tag Debugging checkbox which can be used to log debug messages to your web page’s JavaScript console.

Enter debug mode

Another way to help debug your Google Tag Manager integration is using Google’s Preview mode feature.

This will help identify what values are being sent from your web page’s data layer to each triggered Braze tag and will also explain which tags were or were not triggered.

Enable verbose logging

To allow Braze technical support to access logs while testing, you can enable verbose logging on your Google Tag Manager integration. These logs will appear in the Console tab of your browser’s developer tools.

In your Google Tag Manager integration, navigate to your Braze Initialization Tag and select Enable Web SDK Logging.
