Revamped query editor experience
We’ve redesigned the query editor to make complex panels easier to build and manage. The new experience provides a unified view of your entire data pipeline, queries, expressions, transformations, and related alerts, with clearer visual feedback and faster access to the settings that matter.
Add Prerequisites to Product Discount Functions
Discount functions now support prerequisites for product discount candidates, allowing you to define the "Buy X" portion of a Buy X, Get Y (BXGY) discount. In a BXGY discount, customers must purchase a specified quantity of one product (Buy X) to receive a discount on another product (Get Y).
Add Tags to Discounts
Starting in API version 2026-04, discounts support tags allowing you to efficiently label, group, and organize your discounts. What's new: The tags field has been added to all discount types Tags can be added, updated, and removed via the Admin API For more information, visit the Admin API documentation
Cart and checkout validation adds billing address and PO number error targets
As of API version 2026-04, you can validate billing addresses and purchase order (PO) numbers in Cart and Checkout Validation Functions. We've added billing address and PO Number to the function input graph and introduced new checkout field targets.
Create unpaid orders from subscription billing attempts
In the API 2026-04 release candidate version, you can now include a new field called paymentProcessingPolicy when creating a billing attempt using the subscriptionBillingAttemptCreate mutation. A billing attempt is an action to charge a customer based on their subscription.
