What method allows you to expose a Mule application over HTTP?

To expose a Mule application over HTTP, the appropriate method is to use an HTTP Listener. This component acts as an entry point for incoming HTTP requests. When you configure an HTTP Listener in your Mule application, you specify the host, port, and path on which the application will listen for incoming requests. This setup enables your Mule application to receive and handle requests directly over the HTTP protocol, allowing seamless interaction with external clients, such as web browsers, mobile apps, or other services.

The HTTP Listener effectively sets up the necessary configuration required for your application to respond to HTTP requests. It processes incoming requests and routes them to the appropriate flow within the Mule application for further processing. This is fundamental when building APIs or web services with MuleSoft.

Other choices do not serve this specific purpose in the same way. For example, an HTTP Call is used to send an HTTP request to an external URL, an API Gateway is involved in managing, securing, and routing API traffic but doesn't directly expose a Mule application over HTTP, and an HTTP Connector facilitates integration with HTTP services but does not serve as an endpoint for incoming requests.
