Updating an order's shipping address recalculates taxes as of API version 2026-10
Shopify developer change
MerchantDiff detected this entry in Shopify's official developer changelog on July 30, 2026.
This Shopify update is categorized as Action Required, API, Breaking API Change, GraphQL Admin API, Admin REST API, 2026-10.
What changed
As of API version 2026-10, changing the shipping address on an unfulfilled order through the orderUpdate GraphQL mutation or the REST Admin API order update endpoint recalculates the order's taxes against the new destination. Previously, orderUpdate saved the new address but left the original tax lines unchanged, so the order's totals no longer matched the destination it was shipping to.
