Build a Shopify B2B catalog with a custom price list and assign it to a company location via Admin GraphQL

In-depth guide

Steps

1. Create a price list with priceListCreate, specifying a name, currency, and parent.adjustment (e.g., a percentage discount off the compare-at price) for the default rule.
2. Add fixed override prices for specific variants using priceListFixedPricesAdd, passing an array of {variantId, price{amount, currencyCode}} objects.
3. Create a catalog with catalogCreate of type COMPANY, referencing the priceListId just created and setting status to ACTIVE.
4. Assign the catalog to a company location with catalogContextUpdate, passing the companyLocationId in the context field.
5. Validate by querying catalog(id:) with priceList, publication, and operations fields; also call priceListFixedPrices(first:10) to confirm variant overrides.
6. Publish the catalog by calling publishablePublish with the catalogId so it is visible at the company buyer's storefront session.
