"""The Bot Business Message handler class. Used to handle new bot business messages.
|
|
It is intended to be used with :meth:`~pyrogram.Client.add_handler`
|
|
|
|
For a nicer way to register this handler, have a look at the
|
|
:meth:`~pyrogram.Client.on_bot_business_message` decorator.
|
|
|
|
Parameters:
|
|
callback (``Callable``):
|
|
Pass a function that will be called when a new Message arrives. It takes *(client, message)*
|
|
as positional arguments (look at the section below for a detailed description).
|
|
|
|
filters (:obj:`Filters`):
|
|
Pass one or more filters to allow only a subset of messages to be passed
|
|
in your callback function.
|
|
|
|
Other parameters:
|
|
client (:obj:`~pyrogram.Client`):
|
|
The Client itself, useful when you want to call other API methods inside the message handler.
|
|
|
|
message (:obj:`~pyrogram.types.Message`):
|
|
The received message.
