title: how to use setwebhook in telegram?
body: <p>Hello I'm creating a bot in telegram. I send a http request:
  <br/>
  <a href="https://api.telegram.org/bot(mytoken)/setWebhook?url=https://mywebpagetorespondtobot" rel="noreferrer">https://api.telegram.org/bot(mytoken)/setWebhook?url=https://mywebpagetorespondtobot</a></p>
  
  <p>and I receive this:</p>
  
  <p><code>{"ok":true,"result":true,"description":"Webhook was set"}</code></p>
  
  <p>but It doesn't work.I mean telegram doesn't send updates to the server.
  Is this because I didn't upload my certificate?how should I do that then?</p>
