Removal of pre_tax_price from the Order REST Admin API

Shopify is removing pre_tax_price and pre_tax_price_set fields from the REST Admin API Order endpoints, effective around March 2026. This only affects stores that used the Avalara AvaTax 1.0 integration, which was deprecated April 2025.
Agencies or brands running custom Shopify integrations that pull order line item data via REST for tax reconciliation or reporting will see broken data pipelines. Audit any custom apps or third-party connectors now and migrate to the GraphQL Admin API before fields go dark.
Part of Shopify's broader push to deprecate REST in favor of GraphQL, forcing agencies and brands to modernize integrations or face data gaps.
Audit all REST API calls in your Shopify custom apps or middleware -- if any query pre_tax_price or pre_tax_price_set, migrate to GraphQL Admin API immediately to avoid broken order data.
Within 30 days, test GraphQL Admin API order line item queries in a staging environment to confirm tax data fields return correctly before live cutover.
Bottom Line
Shopify REST tax fields removed -- update to GraphQL or break order data.
