class Update(TelegramObject):
"""This object represents an incoming update.
Objects of this class are comparable in terms of equality. Two objects of this class are
considered equal, if their :attr:`update_id` is equal.
Note:
At most one of the optional parameters can be present in any given update.
.. seealso:: :wiki:`Your First Bot <Extensions---Your-first-Bot>`
Args:
update_id (:obj:`int`): The update's unique identifier. Update identifiers start from a
certain positive number and increase sequentially. This ID becomes especially handy if
you're using Webhooks, since it allows you to ignore repeated updates or to restore the
correct update sequence, should they get out of order. If there are no new updates for
at least a week, then identifier of the next update will be chosen randomly instead of
sequentially.
message (:class:`telegram.Message`, optional): New incoming message of any kind - text,
photo, sticker, etc.
edited_message (:class:`telegram.Message`, optional): New version of a message that is
known to the bot and was edited. This update may at times be triggered by changes to
message fields that are either unavailable or not actively used by your bot.
channel_post (:class:`telegram.Message`, optional): New incoming channel post of any kind
- text, photo, sticker, etc.
edited_channel_post (:class:`telegram.Message`, optional): New version of a channel post
that is known to the bot and was edited. This update may at times be triggered by
changes to message fields that are either unavailable or not actively used by your bot.
inline_query (:class:`telegram.InlineQuery`, optional): New incoming inline query.
chosen_inline_result (:class:`telegram.ChosenInlineResult`, optional): The result of an
inline query that was chosen by a user and sent to their chat partner.
callback_query (:class:`telegram.CallbackQuery`, optional): New incoming callback query.
shipping_query (:class:`telegram.ShippingQuery`, optional): New incoming shipping query.
Only for invoices with flexible price.
pre_checkout_query (:class:`telegram.PreCheckoutQuery`, optional): New incoming
pre-checkout query. Contains full information about checkout.
poll (:class:`telegram.Poll`, optional): New poll state. Bots receive only updates about
manually stopped polls and polls, which are sent by the bot.
poll_answer (:class:`telegram.PollAnswer`, optional): A user changed their answer
in a non-anonymous poll. Bots receive new votes only in polls that were sent
by the bot itself.
my_chat_member (:class:`telegram.ChatMemberUpdated`, optional): The bot's chat member
status was updated in a chat. For private chats, this update is received only when the
bot is blocked or unblocked by the user.
.. versionadded:: 13.4
chat_member (:class:`telegram.ChatMemberUpdated`, optional): A chat member's status was
updated in a chat. The bot must be an administrator in the chat and must explicitly
specify :attr:`CHAT_MEMBER` in the list of
:paramref:`telegram.ext.Application.run_polling.allowed_updates` to receive these
updates (see :meth:`telegram.Bot.get_updates`, :meth:`telegram.Bot.set_webhook`,
:meth:`telegram.ext.Application.run_polling` and
:meth:`telegram.ext.Application.run_webhook`).
.. versionadded:: 13.4
chat_join_request (:class:`telegram.ChatJoinRequest`, optional): A request to join the
chat has been sent. The bot must have the
:attr:`telegram.ChatPermissions.can_invite_users` administrator right in the chat to
receive these updates.
.. versionadded:: 13.8
chat_boost (:class:`telegram.ChatBoostUpdated`, optional): A chat boost was added or
changed. The bot must be an administrator in the chat to receive these updates.
.. versionadded:: 20.8
removed_chat_boost (:class:`telegram.ChatBoostRemoved`, optional): A boost was removed from
a chat. The bot must be an administrator in the chat to receive these updates.
.. versionadded:: 20.8
message_reaction (:class:`telegram.MessageReactionUpdated`, optional): A reaction to a
message was changed by a user. The bot must be an administrator in the chat and must
explicitly specify :attr:`MESSAGE_REACTION` in the list of
:paramref:`telegram.ext.Application.run_polling.allowed_updates` to receive these
updates (see :meth:`telegram.Bot.get_updates`, :meth:`telegram.Bot.set_webhook`,
:meth:`telegram.ext.Application.run_polling` and
:meth:`telegram.ext.Application.run_webhook`). The update isn't received for reactions
set by bots.
.. versionadded:: 20.8
message_reaction_count (:class:`telegram.MessageReactionCountUpdated`, optional): Reactions
to a message with anonymous reactions were changed. The bot must be an administrator in
the chat and must explicitly specify :attr:`MESSAGE_REACTION_COUNT` in the list of
:paramref:`telegram.ext.Application.run_polling.allowed_updates` to receive these
updates (see :meth:`telegram.Bot.get_updates`, :meth:`telegram.Bot.set_webhook`,
:meth:`telegram.ext.Application.run_polling` and
:meth:`telegram.ext.Application.run_webhook`). The updates are grouped and can be sent
with delay up to a few minutes.
.. versionadded:: 20.8
