        .. include:: /_includes/usable-by/users-bots.rst

        Parameters:
            chat_id (``int`` | ``str``):
                Unique identifier (int) or username (str) of the target chat.
                For your personal cloud (Saved Messages) you can simply use "me" or "self".
                For a contact that exists in your Telegram address book you can use his phone number (str).

            animation (``str`` | ``BinaryIO``):
                Animation to send.
                Pass a file_id as string to send an animation that exists on the Telegram servers,
                pass an HTTP URL as a string for Telegram to get an animation from the Internet,
                pass a file path as string to upload a new animation that exists on your local machine, or
                pass a binary file-like object with its attribute ".name" set for in-memory uploads.

            caption (``str``, *optional*):
                Animation caption, 0-1024 characters.

            unsave (``bool``, *optional*):
                By default, the server will save into your own collection any new animation you send.
                Pass True to automatically unsave the sent animation. Defaults to False.

            parse_mode (:obj:`~zeebgram.enums.ParseMode`, *optional*):
                By default, texts are parsed using both Markdown and HTML styles.
                You can combine both syntaxes together.

            caption_entities (List of :obj:`~zeebgram.types.MessageEntity`):
                List of special entities that appear in the caption, which can be specified instead of *parse_mode*.

            has_spoiler (``bool``, *optional*):
                Pass True if the animation needs to be covered with a spoiler animation.

            duration (``int``, *optional*):
                Duration of sent animation in seconds.

            width (``int``, *optional*):
                Animation width.

            height (``int``, *optional*):
                Animation height.

            thumb (``str`` | ``BinaryIO``, *optional*):
                Thumbnail of the animation file sent.
                The thumbnail should be in JPEG format and less than 200 KB in size.
                A thumbnail's width and height should not exceed 320 pixels.
                Thumbnails can't be reused and can be only uploaded as a new file.

            file_name (``str``, *optional*):
                File name of the animation sent.
                Defaults to file's path basename.

            disable_notification (``bool``, *optional*):
                Sends the message silently.
                Users will receive a notification with no sound.

            message_thread_id (``int``, *optional*):
                Unique identifier for the target message thread (topic) of the forum.
                for forum supergroups only.

            reply_to_message_id (``int``, *optional*):

            quote_text (``str``):
                Text of the quote to be sent.

            quote_entities (List of :obj:`~zeebgram.types.MessageEntity`):
                List of special entities that appear in quote text, which can be specified instead of *parse_mode*.

            schedule_date (:py:obj:`~datetime.datetime`, *optional*):
                Date when the message will be automatically sent.

            protect_content (``bool``, *optional*):
                Protects the contents of the sent message from forwarding and saving.

            reply_markup (:obj:`~zeebgram.types.InlineKeyboardMarkup` | :obj:`~zeebgram.types.ReplyKeyboardMarkup` | :obj:`~zeebgram.types.ReplyKeyboardRemove` | :obj:`~zeebgram.types.ForceReply`, *optional*):
                Additional interface options. An object for an inline keyboard, custom reply keyboard,
                instructions to remove reply keyboard or to force a reply from the user.

            progress (``Callable``, *optional*):
                Pass a callback function to view the file transmission progress.
                The function must take *(current, total)* as positional arguments (look at Other Parameters below for a
                detailed description) and will be called back each time a new file chunk has been successfully
                transmitted.

            progress_args (``tuple``, *optional*):
                Extra custom arguments for the progress callback function.
                You can pass anything you need to be available in the progress callback scope; for example, a Message
                object or a Client instance in order to edit the message with the updated progress status.

        Other Parameters:
            current (``int``):
                The amount of bytes transmitted so far.

            total (``int``):
                The total size of the file.

            *args (``tuple``, *optional*):
                Extra custom arguments as defined in the ``progress_args`` parameter.
                You can either keep ``*args`` or add every single extra argument in your function signature.

        Returns:
            :obj:`~zeebgram.types.Message` | ``None``: On success, the sent animation message is returned, otherwise,
            in case the upload is deliberately stopped with :meth:`~zeebgram.Client.stop_transmission`, None is
            returned.

        Example:
            .. code-block:: python

                # Send animation by uploading from local file
                await app.send_animation("me", "animation.gif")
