title: Date filter for Facebook Messenger conversation using GraphAPI
body: <p>I am using Facebook Graph API to read Messenger chat messages using the link below:
  <a href="https://graph.facebook.com/v10.0/me?fields=conversations%7Bid,messages%7Bid,created_time,message,from%7D%7D" rel="nofollow noreferrer">https://graph.facebook.com/v10.0/me?fields=conversations{id,messages{id,created_time,message,from}}</a></p>
  <p>As a conversation may have many messages that are already downloaded. I have tried using since but it doesn't work.</p>
  <p>Is there any way that can add a date filter on it so that I only read new messages from a specific time?</p>
