<p>
  Use this form to manually emit Events from this Agent (usually for testing).
</p>

<p>
  If you add a top-level key called <code>payloads</code> that points to an array of objects, they will be emitted as a series
  of Events.  Otherwise, everything entered will be emitted as a single Event.
</p>

<p>
  Liquid formatting is supported.
