title: Facebook Messenger Bot: Size of Video Attachment? How big can it be?
body: <p>There is no indication as to the the size and format that a video attachment needs to be when being sent through Facebook Messenger, at least in the documentation here: <a href="https://developers.facebook.com/docs/messenger-platform/send-api-reference/video-attachment" rel="nofollow">https://developers.facebook.com/docs/messenger-platform/send-api-reference/video-attachment</a>.</p>
  
  <p>Is there a limit on size? What format does it need to be in?</p>
