# Shopify shipping options move to rateGroups; rateProvider and methodConditions are legacy

- **Provider:** Shopify
- **Endpoint:** `POST /admin/api/{version}/graphql.json`
- **Effective:** 2026-02-24
- **Severity:** medium
- **Change:** field-rename
- **Status:** unverified (secondary reports only; SHAPI does not open fix PRs for it)

## What changed

A shipping option can now hold several tiered rates. DeliveryMethodDefinition.rateGroups and DeliveryRateDefinition.conditions replace the legacy rateProvider and methodConditions fields, and apps that write merchant-managed delivery profiles must move to the new write API.

## What to do

Read shipping options from DeliveryMethodDefinition.rateGroups and DeliveryRateDefinition.conditions, and use the new write API for merchant-managed delivery profiles; app-managed profiles need no change.
