Bot API 5.2

  • Support for Payments 2.0, see this manual for more details about the Bot Payments API.
  • Added the type InputInvoiceMessageContent to support sending invoices as inline query results.
  • Allowed sending invoices to group, supergroup and channel chats.
  • Added the fields max_tip_amount and suggested_tip_amounts to the method sendInvoice to allow adding optional tips to the payment.
  • The parameter start_parameter of the method sendInvoice became optional. If the parameter isn't specified, the invoice can be paid directly from forwarded messages.
  • Added the field chat_type to the class InlineQuery, containing the type of the chat, from which the inline request was sent.
  • Added the type VoiceChatScheduled and the field voice_chat_scheduled to the class Message.
  • Fixed an error in sendChatAction documentation to correctly mention “record_voice” and “upload_voice” instead of “record_audio” and “upload_audio” for related to voice note actions. Old action names will still work for backward compatibility.

⚠️ WARNING! ⚠️
After the next Bot API update (Bot API 5.3) there will be a one-time change of the value of the field file_unique_id in objects of the type PhotoSize and of the fields small_file_unique_id and big_file_unique_id in objects of the type ChatPhoto.

⚠️ WARNING! ⚠️
Service messages about non-bot users joining the chat will be soon removed from large groups. We recommend using the “chat_member” update as a replacement.

⚠️ WARNING! ⚠️
After one of the upcoming Bot API updates, user identifiers will become bigger than 2^31 - 1 and it will be no longer possible to store them in a signed 32-bit integer type. User identifiers will have up to 52 significant bits, so a 64-bit integer or double-precision float type would still be safe for storing them. Please make sure that your code can correctly handle such user identifiers.

March 9, 2021

Bot API 5.1

Added two new update types

  • Added updates about member status changes in chats, represented by the class ChatMemberUpdated and the fields my_chat_member and chat_member in the Update class. The bot must be an administrator in the chat to receive chat_member updates about other chat members. By default, only my_chat_member updates about the bot itself are received.

Improved Invite Links

  • Added the class ChatInviteLink, representing an invite link to a chat.
  • Added the method createChatInviteLink, which can be used to create new invite links in addition to the primary invite link.
  • Added the method editChatInviteLink, which can be used to edit non-primary invite links created by the bot.
  • Added the method revokeChatInviteLink, which can be used to revoke invite links created by the bot.

Voice Chat Info

And More

  • Added the type MessageAutoDeleteTimerChanged and the field message_auto_delete_timer_changed to the class Message.
  • Added the parameter revoke_messages to the method kickChatMember, allowing to delete all messages from a group for the user who is being removed.
  • Added the new administrator privilege can_manage_chat to the class ChatMember and parameter can_manage_chat to the method promoteChatMember. This administrator right is implied by any other administrator privilege.
  • Supported the new bowling animation for the random dice. Choose between different animations (dice, darts, basketball, football, bowling, slot machine) by specifying the emoji parameter in the method sendDice.

⚠️ WARNING! ⚠️
After one of the upcoming Bot API updates, some user identifiers will become bigger than 2^31 - 1 and it will be no longer possible to store them in a signed 32-bit integer type. User identifiers will have up to 52 significant bits, so a 64-bit integer or double-precision float type would still be safe for storing them. Please make sure that your code can correctly handle such user identifiers.

Introducing Bot API 5.0

Run Your Own Bot API Server

  • Bot API source code is now available at telegram-bot-api. You can now run your own Bot API server locally, boosting your bots' performance.
  • Added the method logOut, which can be used to log out from the cloud Bot API server before launching your bot locally. You must log out the bot before running it locally, otherwise there is no guarantee that the bot will receive all updates.
  • Added the method close, which can be used to close the bot instance before moving it from one local server to another.

Transfer Bot Ownership

  • You can now use @BotFather to transfer your existing bots to another Telegram account.


  • Added the parameter ip_address to the method setWebhook, allowing to bypass DNS resolving and use the specified fixed IP address to send webhook requests.
  • Added the field ip_address to the class WebhookInfo, containing the current IP address used for webhook connections creation.
  • Added the ability to drop all pending updates when changing webhook URL using the parameter drop_pending_updates in the methods setWebhook and deleteWebhook.

Working with Groups

  • The getChat request now returns the user's bio for private chats if available.
  • The getChat request now returns the identifier of the linked chat for supergroups and channels, i.e. the discussion group identifier for a channel and vice versa.
  • The getChat request now returns the location to which the supergroup is connected (see Local Groups). Added the class ChatLocation to represent the location.
  • Added the parameter only_if_banned to the method unbanChatMember to allow safe unban.

Working with Files

  • Added the field file_name to the classes Audio and Video, containing the name of the original file.

File Albums

  • Added support for sending and receiving audio and document albums in the method sendMediaGroup.

Live Locations

Anonymous Admins

  • Added the field sender_chat to the class Message, containing the sender of a message which is a chat (group or channel). For backward compatibility in non-channel chats, the field from in such messages will contain the user 777000 for messages automatically forwarded to the discussion group and the user 1087968824 (@GroupAnonymousBot) for messages from anonymous group administrators.
  • Added the field is_anonymous to the class chatMember, which can be used to distinguish anonymous chat administrators.
  • Added the parameter is_anonymous to the method promoteChatMember, which allows to promote anonymous chat administrators. The bot itself should have the is_anonymous right to do this. Despite the fact that bots can have the is_anonymous right, they will never appear as anonymous in the chat. Bots can use the right only for passing to other administrators.
  • Added the custom title of an anonymous message sender to the class Message as author_signature.

  • The field all_members_are_administrators has been removed from the documentation for the Chat object. The field is still returned in the object for backward compatibility, but new bots should use the permissions field instead.
  • Added support for more permissions for group and supergroup members: added the new field can_send_polls to ChatMember object, added can_change_info, can_invite_users, can_pin_messages in ChatMember object for restricted users (previously available only for administrators).
  • The method restrictChatMember now takes the new user permissions in a single argument of the type ChatPermissions. The old way of passing parameters will keep working for a while for backward compatibility.

May 31, 2019

Bot API 4.3

  • Added support for Seamless Telegram Login on external websites.
  • Added the new object LoginUrl and the new field login_url to the InlineKeyboardButton object which allows to automatically authorize users before they go to a URL specified by the bot.

Also in this update:

  • Added the field reply_markup to the Message object, containing the inline keyboard attached to the message.
  • If a message with an inline keyboard is forwarded, the forwarded message will now have an inline keyboard if the keyboard contained only url and login_url buttons or if the message was sent via a bot and the keyboard contained only url, login_url, switch_inline_query or switch_inline_query_current_chat buttons. In the latter case, switch_inline_query_current_chat buttons are replaced with switch_inline_query buttons.
  • Bots now receive the edited_message Update even if only Message.reply_markup has changed.
  • Bots that have the can_edit_messages right in a channel can now use the method editMessageReplyMarkup for messages written by other administrators forever without the 48 hours limit.
  • Don't forget that starting in July 2019, webhook requests from Bot API will be coming from the subnets and Most users won't need to do anything to continue receiving webhooks.

February 13, 2018

Bot API 3.6.

  • Supported text formatting in media captions. Specify the desired parse_mode (Markdown or HTML) when you provide a caption.
  • In supergroups, if the bot receives a message that is a reply, it will also receive the message to which that message is replying – even if the original message is inaccessible due to the bot's privacy settings. (In other words, replying to any message in a supergroup with a message that mentions the bot or features a command for it acts as forwarding the original message to the bot).

May 18, 2017

Introducing Bot API 3.0.

NEW Payment Platform

See Introduction to Bot Payments for a brief overview. If you're not a developer, you may like this user-friendly blog post better.

NEW Video Messages

  • As of Telegram v.4.0, users can send short rounded video messages, using an interface similar to that of voice notes.
  • Added the sendVideoNote method, the new field video_note to Message, the fields record_video_note or upload_video_note to sendChatAction.

NEW Multilingual Bots

  • The User object now may have a language_code field that contains the IETF language tag of the user's language.
  • Thanks to this, your bot can now offer localized responses to users that speak different languages.

More power to admin bots

  • unbanChatMemeber now also works in channels!
  • New method deleteMessage that allows the bot to delete its own messages, as well as messages posted by other in groups and channels where the bot is an administrator.

Minor Changes

  • Replaced the field new_chat_member in Message with new_chat_members (the old field will still be available for a while for compatibility purposes).
  • Inline keyboards with switch_inline_query and switch_inline_query_current_chat can no longer be sent to channels because they are useless there.
  • New fields gif_duration in InlineQueryResultGif and mpeg4_duration in InlineQueryResultMpeg4Gif.

December 4, 2016

Introducing Bot API 2.3.1, a nifty little update that will give you more control over how your bot gets its updates.

  • Use the new field max_connections in setWebhook to optimize your bot's server load
  • Use allowed_updates in setWebhook and getUpdates to selectively subscribe to updates of a certain type. Among other things, this allows you to stop getting updates about new posts in channels where your bot is an admin.
  • deleteWebhook moved out of setWebhook to get a whole separate method for itself.

November 21, 2016

Bot API 2.3

  • Modified bot privacy mode for the sake of consistency.
  • Your bot can now get updates about posts in channels. Added new fields channel_post and edited_channel_post to Update.

  • You can now update high scores to a lower value by using the new force parameter in setGameScore. Handy for punishing cheaters or fixing errors in your game's High Score table.

  • Starting today, messages with high scores will be updated with new high scores by default. Use disable_edit_message in setGameScore if you don't want this.
  • The edit_message parameter from setGameScore is no longer in use. For backward compatibility, it will be taken into account for a while, unless disable_edit_message is passed explicitly.
  • Added the new field forward_from_message_id to Message.
  • Added the new parameter cache_time to answerCallbackQuery. Will eventually work in Telegram apps — somewhere after version 3.14, maybe 3.15.
  • Renamed hide_keyboard to remove_keyboard in ReplyKeyboardRemove for clarity. hide_keyboard will still work for a while for backward compatibility.

October 3, 2016

Bot API 2.2. Introducing a new Gaming Platform! See this introduction for a brief overview.
If you're not a developer, you may like this user-friendly blog post better.

Other changes

  • New field all_members_are_administrators in the Chat object.

February 20, 2016

  • Added the disable_notification parameter to all methods that send messages or any kind.

January 14, 2016

  • You can now collect feedback on which results provided by your inline bot get chosen by the users. Added the setinlinefeedback command for Botfather, new type ChosenInlineResult, new field chosen_inline_result to the Update object.

  • The Chat field in the Message is now of the new type Chat.
  • You can now pass a channel username (in the format @channelusername) in the place of chat_id in all methods (and instead of from_chat_id in forwardMessage). For this to work, the bot must be an administrator in the channel (and that's exactly what Telegram clients don't support yet — adding bots as administrators coming soon).

September 18, 2015

  • Bots can now download files and media sent by users.
  • Added getFile and File.

September 7, 2015

  • You can now pass parameters using application/json (please note that this doesn't work for file uploads: use multipart/form-data to upload files).

  • Added optional field voice to the Message object.
