title: What templating parameters does Flink Stateful Functions URL Path Template support?
body: <p>When deploying Flink Stateful Functions, one needs to specify what the endpoints for the functions are, i.e. what URL does Flink need to hit in order to trigger the execution of a remote function.</p>
  <p>The <a href="https://nightlies.apache.org/flink/flink-statefun-docs-release-3.0/docs/deployment/module/#url-template" rel="nofollow noreferrer">docs</a> state:</p>
  <blockquote>
  <p>The URL template name may contain template parameters that are filled
  in based on the function’s specific type. For example, a message sent
  to message type com.example/greeter will be sent to
  <a href="http://bar.foo.com/greeter" rel="nofollow noreferrer">http://bar.foo.com/greeter</a>.</p>
  </blockquote>
  <pre><code>endpoints:
    - endpoint:
      meta: 
        kind: http
      spec:
        functions: com.example/*
        urlPathTemplate: https://bar.foo.com/{function.name}
  </code></pre>
  <p>What other templating values does the <code>urlPathTemplate</code> support and where are these values taken from?</p>
