# 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
#            email
#         }
#     }

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

set query "{ shop { id name description email } }"

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