Customer calls - EXPRESSO Docs

customerCall runs a Shopify customer-account GraphQL request. The app includes the customer access token when one is available.

declare function customerCall<T>(
  query: string,
  properties?: object
): Promise<GraphQLResponse<T>>;

const result = await customerCall<{ customer: { id: string } | null }>(
  `query { customer { id } }`
);

The resolved value has this shape:

interface GraphQLResponse<T> {
  data: T;
  extensions: object | undefined;
  errors: object[] | undefined;
}

Deprecated calls

Deprecated customer-account calls will be blocked. Migrate to the supported generic signature: put the operation document in query, pass request values in the second properties object, and handle the returned data and errors fields. The app adds the customer access token when one is available.
