(Tcl) 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.

# See Global Unlock Sample for sample code.

# First demonstrate sending a simple request using Shopify private authentication w/ the Chilkat Http API.

# 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.
