An account can hold multiple stores while the API key is account-wide rather than store-scoped. Creating a checkout requires a store relationship alongside the variant relationship, and listing products, orders or subscriptions without a store ID filter returns rows across every store on the account.

Integrations built against a single store routinely omit the filter and then break the day a second store is added, usually by provisioning entitlements from another store's orders. Confirm by listing orders with and without the filter after creating a second store. Keep the store ID in configuration next to the API key, pass the filter on every read, and validate that the store ID on an incoming webhook matches the expected store before acting on it.
