Concrete next actions
- ShopifyRead subdivision membership from Markets conditions and avoid applying unsupported discounts, catalogs, themes or metafields to shipping-only subdivision Markets.View reasoning →
- ShopifyInventory extensions using the deprecated hook or capability and plan equivalent validation Functions before the APIs are removed.View reasoning →
- ShopifyUse the stable identifier for cross-shop legal-entity and tax reconciliation while retaining a null-safe fallback for entities without an organization-level ID.View reasoning →
- ShopifyDetect shops using market-driven shipping, stop treating merchant-owned delivery profiles as authoritative, and migrate each use case to the supported Markets or app-owned profile APIs.View reasoning →
- ShopifyIf a Shopify Plus workflow offers partial-payment terms, evaluate the new deposit fields; otherwise no action is required.View reasoning →
- ShopifyUse the new fields where customer-account views must explain draft-order discounts, and reconcile allocation totals with existing order presentation before rollout.View reasoning →
- ShopifyAudit Customer Account API queries on DraftOrderLineItem and replace discountedUnitPrice with approximateDiscountedUnitPrice before a future removal.View reasoning →
- ShopifyMap current market shipping strategies to the new configuration model and test inherited, disabled and free-threshold behavior before writing live Market settings.View reasoning →
- AmazonReview EU FBM handling-time workflows, update listing title payloads for the split schema by July 27, and make External Fulfillment polling handle ACCEPTED before CREATED is retired.View reasoning →
- ShopifyBefore adopting Admin API 2026-10, replace priceRule title and code reads in draft-order mutation response handling.View reasoning →
- ShopifyReview any app-owned profile assignment logic and enable coversAllItems only when its rates should override assignments for the entire shippable catalog.View reasoning →
- ShopifyIf merchants configure subscription discounts through an extension, expose the two fields and test cycle-limit behavior at checkout before enabling them.View reasoning →
