This update ensures that both APIs offer the same capabilities, enhancing consistency and flexibility for developers. The `multipassIdentifier` field allows you to assign unique identifiers to customers, facilitating seamless authentication between your external website and Shopify store through the Multipass feature. You can now utilize this field in both the `customerCreate` and `customerUpdate` mutations: ```graphql mutation { customerUpdate(input: { id: "gid://shopify/Customer/12345678", multipass_identifier: "your-multipass-identifier-value" }) { customer { id multipassIdentifier } userErrors { field message } } } ``` For further details on working with customers in the Admin GraphQL API, please refer to our [Customer documentation](https://shopify.dev/docs/api/admin-graphql/current/mutations/customerUpdate)
