What changed
Shopify Tax managed mode helps Shopify apply the correct tax behavior for US sales by managing some store settings and API behavior directly. To keep those settings consistent, some Admin API writes now validate against the requirements of managed mode. Managed mode sets requirements that Shopify uses to keep tax behavior consistent across a store. In some cases, the API now prevents apps from writing settings that would conflict with those requirements. In other cases, tax behavior now depends on more specific product or store data instead of simple boolean settings.
