title: How to send message to Facebook channel in Postman using botframework
body: <p>I'm trying to send message to Facebook Channel in botframework from Postman, but I'm receiving 403 forbidden. It works perfectly with Facebook but I need to send some message directly to the Bot Facebook channel, like I do in direct line channel.</p>
  <p>I've try this endpoint: <code>https://facebook.botframework.com/api/v1/bots/{{BOTNAME}}</code> but it always return a 403.</p>
