Notice! Opt in is now available for Braze Web SDK V6 - Action Required

You can now select what version of the Braze SDK you want to use when setting up a Braze connection in the mParticle UI. Braze occasionally makes breaking changes to their SDK, so if you call braze directly in your code, you will have to update your code to ensure your website performs as expected when updating versions of Braze.

Please review the Braze Changelog and V6 migration guide to learn about the differences between V5 and V6 and what changes you will need to make in your code. The most significant breaking change is the removal of the legacy News Feed feature and associated methods (e.g. destroyFeed(), toggleFeed(), showFeed()), in addition to the removal and renaming of several other APIs. There may be API changes that affect you if you call braze directly from your code.

You can opt into the latest major version of the Braze Web SDK whether you implement mParticle's Web SDK using npm or our snippet/CDN.

• Customers who self-host mParticle via npm - You should add @mparticle/web-braze-kit version 6.0.0 or greater in your package.json. You must also select Version 6 under Braze Web SDK Version in the Braze connection settings.
• Customers who load mParticle via snippet/CDN - You must select Version 6 under Braze Web SDK Version in the Braze connection settings.

Step 1: Whether you are using the snippet or self hosting, you need to navigate to your Braze connection settings and select Version 6 from the Braze Web SDK Version drop down.

Step 2: Remove or replace any calls to removed APIs (e.g. News Feed methods such as destroyFeed(), toggleFeed(), showFeed()) and update any renamed APIs per the migration guide. We recommend testing thoroughly in a development environment before releasing.

Step 3: Push Notifications via service-worker.js If you use Push Notifications, your service-worker.js file should be updated to reference https://static.mparticle.com/sdk/js/braze/service-worker-6.5.0.js instead of https://static.mparticle.com/sdk/js/braze/service-worker-5.5.0.js. Your service-worker.js file should now contain:

self.importScripts('https://static.mparticle.com/sdk/js/braze/service-worker-6.5.0.js')

Recommended eCommerce Events (opt-in)

Braze Web SDK 6.9.0+ introduces recommended eCommerce events with the full attribute set (including top-level tax, shipping, and subtotal_value). When the useEcommerceRecommendedEvents setting is enabled on the Braze connection, this kit forwards supported mParticle commerce events using that schema. When the setting is off (the default), commerce forwarding is unchanged and fully backward compatible.

Requirements:

• Minimum Braze Web SDK version: 6.9.0 (braze.logEcommerceEvent with the tax/shipping/subtotal_value attributes). The kit detects support at runtime; if the loaded Braze SDK is older than 6.9.0, commerce events automatically fall back to legacy forwarding.
• Minimum mParticle Braze kit version: the first release that includes this feature (@mparticle/web-braze-kit).

When enabled, mParticle commerce actions map to Braze recommended events:

| mParticle commerce action | Braze recommended event | | :--- | :--- | | add_to_cart | ecommerce.cart_updated (action add) | | remove_from_cart | ecommerce.cart_updated (action remove) | | checkout | ecommerce.checkout_started | | view_detail | ecommerce.product_viewed (one per product) | | purchase | ecommerce.order_placed | | refund | ecommerce.order_refunded (custom event; no typed Braze API) |

tax and shipping map to the recognized top-level attributes from mParticle's TransactionAttributes.tax/shipping. total_discounts and subtotal_value have no native mParticle field and are sourced from the total_discounts / subtotal_value commerce custom attributes (tax/shipping/subtotal_value apply to cart_updated/checkout_started/order_placed; total_discounts to order_placed/refund). Any remaining attribute without a direct Braze equivalent (cart_id, checkout_id, source, product brand/category/coupon_code/position, etc.) is placed inside the event- or product-level metadata object, per Braze's strict recommended-event schema. source is reported as "web". Any commerce action not listed above continues to use legacy forwarding.
