Method: updates.getChannelDifference

Back to methods index

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.

MadelineProto Example (now async for huge speed and parallelism!):

if (!file_exists('madeline.php')) {
    copy('', 'madeline.php');
include 'madeline.php';

$MadelineProto = new \danog\MadelineProto\API('session.madeline');

$updates_ChannelDifference = $MadelineProto->updates->getChannelDifference(force: $Bool, channel: $InputChannel, filter: $ChannelMessagesFilter, pts: $int, limit: $int, );
