The default order is from newest to oldest, but this behaviour can be changed with the `reverse` parameter. If either `search`, `filter` or `from_user` are provided, :tl:`messages.Search` will be used instead of :tl:`messages.getHistory`. .. note:: Telegram's flood wait limit for :tl:`GetHistoryRequest` seems to be around 30 seconds per 10 requests, therefore a sleep of 1 second is the default for this limit (or above). Arguments entity (`entity`): The entity from whom to retrieve the message history. It may be `None` to perform a global search, or to get messages by their ID from no particular chat. Note that some of the offsets will not work if this is the case. Note that if you want to perform a global search, you **must** set a non-empty `search` string, a `filter`. or `from_user`. limit (`int` | `None`, optional): Number of messages to be retrieved. Due to limitations with the API retrieving more than 3000 messages will take longer than half a minute (or even more based on previous calls). The limit may also be `None`, which would eventually return the whole history. offset_date (`datetime`): Offset date (messages *previous* to this date will be retrieved). Exclusive. offset_id (`int`): Offset message ID (only messages *previous* to the given ID will be retrieved). Exclusive. max_id (`int`): All the messages with a higher (newer) ID or equal to this will be excluded. min_id (`int`): All the messages with a lower (older) ID or equal to this will be excluded. add_offset (`int`): Additional message offset (all of the specified offsets + this offset = older messages). search (`str`): The string to be used as a search query. filter (:tl:`MessagesFilter` | `type`): The filter to use when returning messages. For instance, :tl:`InputMessagesFilterPhotos` would yield only messages containing photos. from_user (`entity`): Only messages from this entity will be returned. wait_time (`int`): Wait time (in seconds) between different :tl:`GetHistoryRequest`. Use this parameter to avoid hitting the ``FloodWaitError`` as needed. If left to `None`, it will default to 1 second only if the limit is higher than 3000. If the ``ids`` parameter is used, this time will default to 10 seconds only if the amount of IDs is higher than 300. ids (`int`, `list`): A single integer ID (or several IDs) for the message that should be returned. This parameter takes precedence over the rest (which will be ignored if this is set). This can for instance be used to get the message with ID 123 from a channel. Note that if the message doesn't exist, `None` will appear in its place, so that zipping the list of IDs with the messages can match one-to-one. .. note:: At the time of writing, Telegram will **not** return :tl:`MessageEmpty` for :tl:`InputMessageReplyTo` IDs that failed (i.e. the message is not replying to any, or is replying to a deleted message). This means that it is **not** possible to match messages one-by-one, so be careful if you use non-integers in this parameter. reverse (`bool`, optional): If set to `True`, the messages will be returned in reverse order (from oldest to newest, instead of the default newest to oldest). This also means that the meaning of `offset_id` and `offset_date` parameters is reversed, although they will still be exclusive. `min_id` becomes equivalent to `offset_id` instead of being `max_id` as well since messages are returned in ascending order. You cannot use this if both `entity` and `ids` are `None`. reply_to (`int`, optional): If set to a message ID, the messages that reply to this ID will be returned. This feature is also known as comments in posts of broadcast channels, or viewing threads in groups. This feature can only be used in broadcast channels and their linked megagroups. Using it in a chat or private conversation will result in ``telethon.errors.PeerIdInvalidError`` to occur. When using this parameter, the ``filter`` and ``search`` parameters have no effect, since Telegram's API doesn't support searching messages in replies. .. note:: This feature is used to get replies to a message in the *discussion* group. If the same broadcast channel sends a message and replies to it itself, that reply will not be included in the results. scheduled (`bool`, optional): If set to `True`, messages which are scheduled will be returned. All other parameter will be ignored for this, except `entity`. Yields Instances of `Message `. Example .. code-block:: python # From most-recent to oldest async for message in client.iter_messages(chat): print(message.id, message.text) # From oldest to most-recent async for message in client.iter_messages(chat, reverse=True): print(message.id, message.text) # Filter by sender async for message in client.iter_messages(chat, from_user='me'): print(message.text) # Server-side search with fuzzy text async for message in client.iter_messages(chat, search='hello'): print(message.id) # Filter by message type: from telethon.tl.types import InputMessagesFilterPhotos async for message in client.iter_messages(chat, filter=InputMessagesFilterPhotos): print(message.photo) # Getting comments from a post in a channel: async for message in client.iter_messages(channel, reply_to=123): print(message.chat.title, message.text) """ if ids is not None: if not utils.is_list_like(ids): ids = [ids] return _IDsIter( client=self, reverse=reverse, wait_time=wait_time, limit=len(ids), entity=entity, ids=ids ) return _MessagesIter( client=self, reverse=reverse, wait_time=wait_time, limit=limit, entity=entity, offset_id=offset_id, min_id=min_id, max_id=max_id, from_user=from_user, offset_date=offset_date, add_offset=add_offset, filter=filter, search=search, reply_to=reply_to, scheduled=scheduled ) async def get_messages(self: 'TelegramClient', *args, **kwargs) -> 'hints.TotalList': """ Same as `iter_messages()`, but returns a `TotalList ` instead.

This is so because any integer limit would be rather arbitrary and it's common to only want to fetch one message, but if a range is specified it makes sense that it should return the entirety of it.

Sending a ``/start`` command with a parameter (like ``?start=data``) is also done through this method. Simply send ``'/start data'`` to the bot. See also `Message.respond() ` and `Message.reply() `. Arguments entity (`entity`): To who will it be sent. message (`str` | `Message `): The message to be sent, or another message object to resend. The maximum length for a message is 35,000 bytes or 4,096 characters. Longer messages will not be sliced automatically, and you should slice them manually if the text to send is longer than said length. reply_to (`int` | `Message `, optional): Whether to reply to a message or not. If an integer is provided, it should be the ID of the message that it should reply to. attributes (`list`, optional): Optional attributes that override the inferred ones, like :tl:`DocumentAttributeFilename` and so on. parse_mode (`object`, optional): See the `TelegramClient.parse_mode ` property for allowed values. Markdown parsing will be used by default. formatting_entities (`list`, optional): A list of message formatting entities. When provided, the ``parse_mode`` is ignored. link_preview (`bool`, optional): Should the link preview be shown? file (`file`, optional): Sends a message with a file attached (e.g. a photo, video, audio or document). The ``message`` may be empty. thumb (`str` | `bytes` | `file`, optional): Optional JPEG thumbnail (for documents). **Telegram will ignore this parameter** unless you pass a ``.jpg`` file! The file must also be small in dimensions and in disk size. Successful thumbnails were files below 20kB and 320x320px. Width/height and dimensions/size ratios may be important. For Telegram to accept a thumbnail, you must provide the dimensions of the underlying media through ``attributes=`` with :tl:`DocumentAttributesVideo` or by installing the optional ``hachoir`` dependency. force_document (`bool`, optional): Whether to send the given file as a document or not. clear_draft (`bool`, optional): Whether the existing draft should be cleared or not. buttons (`list`, `custom.Button `, :tl:`KeyboardButton`): The matrix (list of lists), row list or button to be shown after sending the message. This parameter will only work if you have signed in as a bot. You can also pass your own :tl:`ReplyMarkup` here. All the following limits apply together: * There can be 100 buttons at most (any more are ignored). * There can be 8 buttons per row at most (more are ignored). * The maximum callback data per button is 64 bytes. * The maximum data that can be embedded in total is just over 4KB, shared between inline callback data and text. silent (`bool`, optional): Whether the message should notify people in a broadcast channel or not. Defaults to `False`, which means it will notify them. Set it to `True` to alter this behaviour. background (`bool`, optional): Whether the message should be send in background. supports_streaming (`bool`, optional): Whether the sent video supports streaming or not. Note that Telegram only recognizes as streamable some formats like MP4, and others like AVI or MKV will not work. You should convert these to MP4 before sending if you want them to be streamable. Unsupported formats will result in ``VideoContentTypeError``. schedule (`hints.DateLike`, optional): If set, the message won't send immediately, and instead it will be scheduled to be automatically sent at a later time. comment_to (`int` | `Message `, optional): Similar to ``reply_to``, but replies in the linked group of a broadcast channel instead (effectively leaving a "comment to" the specified message). This parameter takes precedence over ``reply_to``. If there is no linked chat, `telethon.errors.sgIdInvalidError` is raised. nosound_video (`bool`, optional): Only applicable when sending a video file without an audio track. If set to ``True``, the video will be displayed in Telegram as a video. If set to ``False``, Telegram will attempt to display the video as an animated gif. (It may still display as a video due to other factors.) The value is ignored if set on non-video files. This is set to ``True`` for albums, as gifs cannot be sent in albums. Returns The sent `custom.Message `.

See also `Message.edit() `. Arguments entity (`entity` | `Message `): From which chat to edit the message. This can also be the message to be edited, and the entity will be inferred from it, so the next parameter will be assumed to be the message text. You may also pass a :tl:`InputBotInlineMessageID` or :tl:`InputBotInlineMessageID64`, which is the only way to edit messages that were sent after the user selects an inline query result. message (`int` | `Message ` | `str`): The ID of the message (or `Message ` itself) to be edited. If the `entity` was a `Message `, then this message will be treated as the new text. text (`str`, optional): The new text of the message. Does nothing if the `entity` was a `Message `. parse_mode (`object`, optional): See the `TelegramClient.parse_mode ` property for allowed values. Markdown parsing will be used by default. attributes (`list`, optional): Optional attributes that override the inferred ones, like :tl:`DocumentAttributeFilename` and so on. formatting_entities (`list`, optional): A list of message formatting entities. When provided, the ``parse_mode`` is ignored. link_preview (`bool`, optional): Should the link preview be shown? file (`str` | `bytes` | `file` | `media`, optional): The file object that should replace the existing media in the message. thumb (`str` | `bytes` | `file`, optional): Optional JPEG thumbnail (for documents). **Telegram will ignore this parameter** unless you pass a ``.jpg`` file! The file must also be small in dimensions and in disk size. Successful thumbnails were files below 20kB and 320x320px. Width/height and dimensions/size ratios may be important. For Telegram to accept a thumbnail, you must provide the dimensions of the underlying media through ``attributes=`` with :tl:`DocumentAttributesVideo` or by installing the optional ``hachoir`` dependency. force_document (`bool`, optional): Whether to send the given file as a document or not. buttons (`list`, `custom.Button `, :tl:`KeyboardButton`): The matrix (list of lists), row list or button to be shown after sending the message. This parameter will only work if you have signed in as a bot. You can also pass your own :tl:`ReplyMarkup` here. supports_streaming (`bool`, optional): Whether the sent video supports streaming or not. Note that Telegram only recognizes as streamable some formats like MP4, and others like AVI or MKV will not work. You should convert these to MP4 before sending if you want them to be streamable. Unsupported formats will result in ``VideoContentTypeError``. schedule (`hints.DateLike`, optional): If set, the message won't be edited immediately, and instead it will be scheduled to be automatically edited at a later time. Note that this parameter will have no effect if you are trying to edit a message that was sent via inline bots. Returns The edited `Message `, unless `entity` was a :tl:`InputBotInlineMessageID` or :tl:`InputBotInlineMessageID64` in which case this method returns a boolean. Raises ``MessageAuthorRequiredError`` if you're not the author of the message but tried editing it anyway. ``MessageNotModifiedError`` if the contents of the message were not modified at all. ``MessageIdInvalidError`` if the ID of the message is invalid (the ID itself may be correct, but the message with that ID cannot be edited). For example, when trying to edit messages with a reply markup (or clear markup) this error will be raised.
