// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

Dim http As New Chilkat.Http

// 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.
http.Login = "SHOPIFY_PRIVATE_API_KEY"
http.Password = "SHOPIFY_PRIVATE_API_SECRET_KEY"
http.BasicAuth = True

// 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
//            email
//         }
//     }

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

Dim query As String
query = "{ shop { id name description email } }"

// My store name is "chilkat".  Use your store name here instead.

// Examine the response code.

    System.DebugLog("Response body:")
    System.DebugLog(resp.BodyStr)

    System.DebugLog(resp.Header)
