Warning: this is a low-level, complex method that must never be used directly.

The event handler provides a high-level abstraction that must be used instead of this method to fetch updates. If you want to fetch all users of a bot using a bot token, use getDialogIds or the high-level broadcast API, instead.

You cannot use this method directly, please use the event handler, instead.

Parameters:

Name	Type	Description	Required
force	Bool	Set to true to skip some possibly unneeded updates and reduce server-side load	Optional
channel	Username, chat ID, Update, Message or InputChannel	The channel	Optional
filter	ChannelMessagesFilter	Messsage filter	Optional
pts	int	Persistent timestamp (see updates)	Optional
limit	int	How many updates to fetch, max 100000 Ordinary (non-bot) users are supposed to pass 10-100	Optional

Return type: updates.ChannelDifference

Can bots use this method: YES
