// This example will use private authentication (which is HTTP Basic authentication)
// See the other Chilkat Shopify examples for OAuth2 authentication.
// To use HTTP Basic Authentication with any HTTP request, we simply set the Login, Password, and BasicAuth properties.
// Important: All HTTP requests using Basic authentication must be over SSL/TLS.

// We're going to do a POST  https://{shop}.myshopify.com/admin/api/2021-04/graphql.json
// Make sure to replace "chilkat" with your store name.

// The body of the request will be:
//    {
//        shop {
//            id
//            name
//            description

// The above query is not JSON.  It looks like JSON, but it's actually not.
// We'll just make it one line:
