Cart Viewed
Fire the cart_viewed event when a visitor lands on the cart page or opens a cart drawer/modal with the full list of items they intend to purchase. This event is a high-intent mid-funnel signal — visitors who view their cart are statistically much more likely to convert, which makes them a prime audience for retargeting and abandonment recovery flows.
Fire it once per cart page view, with products[] reflecting the current state of the cart (every line item with its current quantity). If the visitor stays on the cart page and modifies quantities or removes items, do not re-fire cart_viewed — use product_added_to_cart and product_removed_from_cart for those individual actions.
This event is the DATA Reshape equivalent of the standard view-cart event in every major advertising and analytics platform — push it once and Reshape fans it out to every connected destination with the correct platform-specific name and field mapping, so you do not need to fire gtag, fbq, ttq or other tracking function calls in parallel.
- Google Analytics 4 —
view_cart(withitems,value,currency). - Google Ads — dynamic remarketing cart-view signal, used for cart-abandonment audiences.
- Meta Pixel / Meta Conversions API —
ViewContentwith cart context (Meta has no dedicatedViewCart). - TikTok Pixel / TikTok Events API —
ViewContentwith cart context (TikTok has no dedicatedViewCart). - Other connected destinations — mapped automatically based on each destination's native schema.
A single Reshape event can produce one or more native events per destination, with different characteristics depending on each website's destination configuration (active pixels, server endpoints, event-mapping rules).
Complete Reference
The cart_viewed event accepts the following objects and fields. Required fields must always be present in the payload — everything else is optional but strongly recommended.

Custom properties (event.properties, user.properties, products[*].properties) are fully processed server-side. On browser-side pixels and tags, only a subset may be available. Server-side processing can also enrich the outgoing payload with additional parameters derived from context and data quality.
Best Practices
- Fire on cart page load — fire once when the cart page loads or the cart drawer opens, not on each cart-state update.
- Include the full cart —
products[]must contain every line item with current quantities. Missing items hurt cart-abandonment audience quality. event.value= sum ofprice × quantity— before shipping and order-level discounts.- Use consistent product IDs across the funnel — same
products[*].idas inproduct_viewedandproduct_added_to_cart, so destinations can build proper view→cart→checkout→purchase funnels. - Include
userwhen available — even just an email enables high-intent audience targeting and equivalent flows in connected destinations.
