title: How could I invoke an api without access token in APIM 2.0
body: <p>I couldn't find a way to set "Auth Type" when I tried to create api in api-publisher.</p>
  
  <p>Then I have to add Authentication to request header, but for some reason I don't want to set the auth header for my request.</p>
  
  <p>And I found something in APIM Documention that said I should set "Auth Type" to "None", but I could not see this selection in api-creating page (APIM 2.0).</p>
  
  <p>Will be appreciated if there are any help..thanks!!</p>
