This class sets webhooks and listens to a given url and port.

0.0.0.0
:param port: A port which will be used to listen to webhooks.
:param url_path: Path to the webhook. Defaults to /token
:param certificate: Path to the certificate file.
:param certificate_key: Path to the certificate key file.
:param webhook_url: Webhook URL.
:param max_connections: Maximum allowed number of simultaneous HTTPS connections to the webhook for update delivery, 1-100. Defaults to 40. Use lower values to limit the load on your bot's server, and higher values to increase your bot's throughput.
:param allowed_updates: A JSON-serialized list of the update types you want your bot to receive. For example, specify [“message”, “edited_channel_post”, “callback_query”] to only receive updates of these types. See Update for a complete list of available update types. Specify an empty list to receive all updates regardless of type (default). If not specified, the previous setting will be used.
:param ip_address: The fixed IP address which will be used to send webhook requests instead of the IP address resolved through DNS
:param drop_pending_updates: Pass True to drop all pending updates
