You might do it if your API exists within a virtual network (where you know the access is secure even if HTTPS is not used). <br/>You might want to use "HTTPS termination" to save on some CPU cycles.|
     |**URL suffix**|"*hbin*"| The suffix is a name that identifies this specific API in this APIM instance. It has to be unique in this APIM instance.|
     |**Products**|"*Unlimited*" |Publish the API by associating the API with a product. If you want for the API to be published and be available to developers, add it to a product. You can do it during API creation or set it later.<br/><br/>Products are associations of one or more APIs. You can include a number of APIs and offer them to developers through the developer portal. <br/>Developers must first subscribe to a product to get access to the API. When they subscribe, they get a subscription key that is good for any API in that product. If you created the APIM instance, you are an administrator already, so you are subscribed to every product by default.<br/><br/> By default, each API Management instance comes with two sample products: **Starter** and **Unlimited**.|
