Snippets for APIs that rely on checking the Location header of the response lack code to do so

Some example APIs that rely on checking the Location header:

authenticationMethod: resetPassword
Create schema

We show how to make the call and get the result back, but the result doesn't expose headers. For example, the resetPassword case in C# returns a PasswordResetResponse that has no access to the headers.
