Create and configure Markets in the Shopify admin or via the marketCreate Admin GraphQL mutation, specifying countries and a primary country.
Set market-specific pricing using marketCatalogCreate to create a catalog scoped to a market, and attach a price list with currency and pricing adjustments.
Use marketUpdate to configure currency, market-specific domains or subfolders, and tax-inclusive pricing settings for each market.
In the Storefront API, set the buyer's countryCode on the cart via cartBuyerIdentityUpdate or pass it as a @inContext directive argument (e.g., @inContext(country: CA)) on product queries to retrieve localized prices.
Localized prices are returned in the product.variants.price and cart.cost fields when countryCode is resolved to a market with a catalog.
Test price resolution by querying product.variants.contextualPricing with country argument to verify correct prices before and after enabling a market catalog.
Known gotchas
If a product is not published to the market's catalog publication, it will not appear in Storefront API queries scoped to that market; ensure catalog-to-publication links are correct.
Tax-inclusive pricing settings differ per market; enabling tax-inclusive display changes the price shown to buyers but not the underlying price record—verify your display logic handles both cases.
