+<Update label="Aug 14, 2026" description="X Ads API">
+  ### New `WEB_CONVERSION` metrics
+
+  We added eight new metrics to the `WEB_CONVERSION` metric group on the [X Ads API Analytics endpoints](/x-ads-api/analytics). You can now request the following metrics alongside the existing web conversion set:
+
+  - `conversion_add_to_carts`
+  - `conversion_checkouts_initiated`
+  - `conversion_content_views`
+  - `conversion_payment_info_additions`
+  - `conversion_add_to_wishlists`
+  - `conversion_searches`
+  - `conversion_landing_page_views`
+  - `conversion_subscriptions`
+
+  Each returns the number of conversions for that event type along with the corresponding sale amount and order quantity, and supports the `PLATFORMS` and `CONVERSION_TAGS` segmentations.
