(SQL Server) Shopify OAuth2 Authentication

Demonstrates obtaining an access token for a Shopify application using OAuth2 authentication. This example is for non-web-apps, and requires that a browser window be displayed to get authorization from the user.

A web-based application would not obtain an OAuth2 token in this way, because the redirect URL would route back to the web application.

Note: Once an access token is in hand, the remainder of the Chilkat examples, which use an already-obtained access token, apply to both web and non-web apps.
