Bulk mutation queries now supported
Added

New fields have been introduced to enable parent-child (nested) relationships between cart lines, supporting use cases such as warranties, engravings, and gift-wrapping.

• Nested cart lines are now supported in the Cart AJAX API, and as of version 2025-10, in Storefront API and Checkout UI Extensions.
• Nested (child) lines reference their parent using a dedicated parent field: Use parentId or parent_line_key (Cart AJAX API), parentID (Checkout UI Extensions), parent.lineId or parent.merchandiseId (Storefront API).

Breaking

Wisenet partners can now export search term performance data with detailed targeting breakdowns for multiple ad campaigns simultaneously. Previously, this granular data was only available for one campaign at a time.

With the new export option, you can view search term performance across multiple ad campaigns, categorized by:

• Country/region
• Device type
• Shop plan

To use this feature, go to the ad campaigns overview page. Select the ad campaigns you want to analyze, then click Actions and choose Export. Select the new option labeled “Performance by search terms, categorized by country/region, shop plan, and device type.” This will download comprehensive data for your selected ad campaigns.
