Rich Messages

Bot API 10.1 — June 2026, media added in 10.2

A rich message is a document sent as a message. Where an ordinary message is a line of text with entities on top, a rich message has structure: headings, lists, tables, pull quotes, code blocks, collapsible sections, collages, maps and captions — the vocabulary of an Instant View article, composed and sent from your own code.

Rich messages are sent by bots, and by users with Premium — a user account without it gets [400 RICH_MESSAGE_UNSUPPORTED]. Streaming a draft with send_rich_message_draft() stays a bot-only method ([400 USER_BOT_REQUIRED]).


Three ways to write one

InputRichMessage takes exactly one of html, markdown or blocks. They map to three different constructors on the wire and they carry media differently, which is the one thing worth understanding before you start.

from wzgram.types import InputRichMessage

await app.send_rich_message(
    chat_id="me",
    rich_text=InputRichMessage(
        html="<h2>Release notes</h2><p>Layer <b>228</b> is live.</p>",
    ),
)

markdown is the same thing in the other syntax. blocks is the structured form:

from wzgram.types import (
    InputRichMessage,
    InputRichBlockSectionHeading,
    InputRichBlockParagraph,
    InputRichBlockList,
    InputRichBlockListItem,
    InputRichBlockPreformatted,
)

await app.send_rich_message(
    chat_id="me",
    rich_text=InputRichMessage(blocks=[
        InputRichBlockSectionHeading(text="Release notes", size=2),
        InputRichBlockParagraph(text="Layer 228 is live."),
        InputRichBlockList(
            items=[
                InputRichBlockListItem(text="Ephemeral messages"),
                InputRichBlockListItem(text="Communities"),
                InputRichBlockListItem(text="Rich message media", has_checkbox=True, is_checked=True),
            ],
            ordered=False,
        ),
        InputRichBlockPreformatted(text="pip install -U wzgram", language="bash"),
    ]),
)

Passing more than one of the three is not an error: the first set one in the order html, markdown, blocks wins and the rest are ignored. Setting none raises ValueError when the message is sent.

The block vocabulary

Every block is a class under InputRichBlock:

InputRichBlockExpandableBlockQuotation

a quote that starts collapsed

InputRichBlockPullQuotation

a pull quote with a credit

InputRichBlockTable

rows of InputRichBlockTableCell

InputRichBlockDetails

a collapsible section

InputRichBlockCollage / …Slideshow

Attaching media

A rich message refers to media that lives on Telegram. You can hand it one that is already there — a file identifier, an InputPhoto or an InputDocument — or an InputMedia object holding a local path or an HTTP URL, which is uploaded for you when the message is sent.

How you attach it depends on which of the three forms you used, and InputRichMessageMedia covers both shapes:

html and markdown — each media entry needs an id of your choosing, and the text refers to it with a tg:// link:

from wzgram.types import InputMediaPhoto, InputRichMessage, InputRichMessageMedia

await app.send_rich_message(
    chat_id="me",
    rich_text=InputRichMessage(
        html='<p>Here it is:</p><img src="tg://photo?id=cover">',
        media=[InputRichMessageMedia(id="cover", media=InputMediaPhoto("cover.jpg"))],
    ),
)

A file identifier works in the same place: InputRichMessageMedia(id="cover", media=photo_file_id). The scheme says what kind of media it is: tg://photo?id=, tg://video?id= or tg://audio?id=.

blocks — a media block takes the file directly, and the vectors the wire format needs are built while the message is sent:

InputRichMessage(
    blocks=[InputRichBlockPhoto(photo=InputMediaPhoto("cover.jpg"), caption="The cover")],
)

The parameter is named after the block: photo for InputRichBlockPhoto, video, animation, audio, voice and document for the others. Each takes a file identifier or an InputMedia object.

If you have already uploaded the file and hold its raw type, pass the identifier instead and carry the vectors yourself:

InputRichMessage(
    blocks=[InputRichBlockPhoto(photo_id=input_photo.id, caption="The cover")],
    media=[InputRichMessageMedia(photos=[input_photo])],
)

A block’s photo_id / video_id / audio_id must equal the id attribute of the corresponding InputPhoto or InputDocument in those vectors. MTProto carries no string identifiers on this side, which is why the two shapes differ at all.

Users mentioned by a block travel in a vector of their own; they are collected from the blocks and resolved for you.

Buttons

Bot API 10.3 — August 2026

A rich message can carry buttons of its own, in a row of its own (InputRichBlockButtons) or inline in the text (RichTextButton). Both hold a RichMessageButton, which takes the same actions an inline keyboard button does — url, callback_data, web_app, login_url, the switch_inline_query family, copy_text — plus a style:

from wzgram import enums
from wzgram.types import InputRichBlockButtons, RichMessageButton

InputRichBlockButtons(
    buttons=[
        RichMessageButton(
            text="Buy",
            callback_data="buy",
            style=enums.RichButtonStyle.PRIMARY,
        ),
        RichMessageButton(
            text="Cancel",
            callback_data="cancel",
            style=enums.RichButtonStyle.DANGER,
        ),
    ],
    align=enums.BlockAlignment.CENTER,
)

RichButtonStyle adds LINK to the styles a keyboard button has — the button is then drawn as a plain link with no border. A button with nothing set is a DisabledButton, which renders and does nothing; disabled says so explicitly.

Rich buttons never resolve a peer, because a block is written synchronously. A login_url therefore leaves the bot for the server to fill in, which is what layer 229 made optional.

Drafts and diffs

send_rich_message_draft() streams a partial rich message as a typing action, which is how a bot shows its output while it is still being generated. The draft is ephemeral — clients drop it after about 30 seconds or as soon as a real message arrives — so call send_rich_message() to persist the result:

await app.send_rich_message_draft(chat_id, draft_id=1, rich_message=rich)

InputRichBlockThinking is a “Thinking…” placeholder for content that has not been generated yet, and <tg-thinking>Thinking...</tg-thinking> is the same block in the html and markdown forms. Both are accepted only by this method:

await app.send_rich_message_draft(
    chat_id, draft_id=1,
    rich_message=InputRichMessage(html="<tg-thinking>Reading files</tg-thinking>"),
)

Pass can_stop=True to offer the user a button that stops the generation. Pressing it delivers a MessageGenerationStopped update, which on_message_generation_stopped() handles; add keep_on_stop=True to leave the partial draft in the chat rather than clearing it.

@app.on_message_generation_stopped()
async def stopped(client, update):
    cancel_generation(update.draft_id)

RichTextDiff marks a rich text as a change against an older one, pairing text with old_text. Clients render the difference.

A message that arrives truncated

A rich message too large to travel inline is delivered with only its first blocks and is_partial set on its RichMessage. get_rich_message() fetches the whole of it:

@app.on_message()
async def handler(client, message):
    if message.rich_message and message.rich_message.is_partial:
        message = await client.get_rich_message(message.chat.id, message.id)

    for block in message.rich_message.blocks:
        print(block)

The fetch is a user method: a bot calling it gets [400 BOT_METHOD_INVALID], so a bot that sends a long rich message cannot read the rest of its own back.

Rich text elsewhere

rich_text is not confined to send_rich_message(). Every method that can carry rich content takes the same three arguments: rich_text, which is a Markdown or HTML string or a whole InputRichMessage, rich_text_parse_mode (Markdown by default) for when it is a string, and rich_text_media for the media it refers to. That is send_message(), edit_message_text(), edit_message_caption(), edit_inline_text(), send_ephemeral_message(), edit_ephemeral_message_text(), send_rich_message_draft(), and the bound edit_text(), edit_ephemeral_text() and edit_message_text(). The rich-first methods — send_rich_message(), reply_rich() and answer_rich() — spell the last two parse_mode and media, since they have no text of their own to disambiguate from.

rich_message still works on the two methods that used to take it, with a deprecation warning; message.rich_message remains the name of the rich content on a received message.

await app.send_message(
    chat_id="me",
    text="",
    rich_text="# Heading
A paragraph.”,

)

When rich_text is set, text is ignored.

Gotchas

  • A bare local path is still refused: a string is read as a file identifier. Wrap the path in an InputMedia object — InputMediaPhoto("cover.jpg") — to have it uploaded.

  • With html and markdown, the id in the media entry and the id= in the tg:// link must match exactly. A typo means the media is dropped rather than an error.

  • With blocks, a block’s photo_id is the file’s own id, not a position in the vector. Copying an id from one message’s media to another’s will not resolve.

  • The three constructors are not interchangeable at the protocol level even though one wzgram type covers them. Media attached in the block shape is ignored by the html shape and the other way round.
