title: Access to API through Azure API Management without setting Ocp-Apim-Subscription-Key
body: <p>Is there a way to create a API which does not require the caller to pass in the Ocp-Apim-Subscription-Key without having to create a separate product and un-checking the Require subscription checkbox. What I want is within the same product to have some APIs which require the Ocp-Apim-Subscription-Key to be passed in and some APIs which can be called without passing the Ocp-Apim-Subscription-Key in the request header.</p>
