(PureBasic) Shopify Private Authentication for Private Apps

Shopify private authentication is for interacting with your own store through private applications. It uses HTTP "Basic" authentication with your Shopify private application key and secret key.

This example demonstrates how to send a private authenticated request using Chilkat Http, and then the same using Chilkat Rest.
