|
|
Occurs whenever you sign in as a bot and a user
|
|
clicks one of the inline buttons on your messages.
|
|
|
|
Note that the `chats` parameter will **not** work with normal
|
|
IDs or peers if the clicked inline button comes from a "via bot"
|
|
message. The `chats` parameter also supports checking against the
|
|
`chat_instance` which should be used for inline callbacks.
|
|
|
|
Args:
|
|
data (`bytes`, `str`, `callable`, optional):
|
|
If set, the inline button payload data must match this data.
|
|
A UTF-8 string can also be given, a regex or a callable. For
|
|
instance, to check against ``'data_1'`` and ``'data_2'`` you
|
|
can use ``re.compile(b'data_')``.
|
|
|
|
pattern (`bytes`, `str`, `callable`, `Pattern`, optional):
|
|
If set, only buttons with payload matching this pattern will be handled.
|
|
You can specify a regex-like string which will be matched
|
|
against the payload data, a callable function that returns `True`
|
|
if a the payload data is acceptable, or a compiled regex pattern.
