Step by Step Guide to No Authentication External Credential in Salesforce

In this guide we will learn how to configure & use “No Authentication” External Credential to integrate Salesforce with an external system. But before we dive into this guide, here is an overview of all the different authentication protocols that external credentials support.

    Ashish & Friends, When I go thru this step by step guide and when I hit page 31, (New HTTP Callout) I am not provided with “Connect for Schema” under “Select Sample Response Method” I only see “Provide Sample Response” I checked the URL & path and they all seem right. Is there something I am missing? I have tried in 2 dev orgs and in both the same result. Thanks in advance,
