Triggers on mrkdwn, Slack formatting, Slack markdown, Slack bold, Slack italic, Slack links, mentions, dates, escaping, text objects, verbatim, plain_text, markdown blocks, markdown_text, rich_text, Work Objects, streaming text, notification fallbacks, accessibility, auto-parsing, parse, link_names, unfurls, and mrkdwn_in. Use when formatting Slack messages, composing text objects, escaping user content, choosing between mrkdwn and standard Markdown, adding mentions or localized dates, streaming Markdown, authoring Work Object fields or comments, or debugging Slack text rendering.\n---\n\n# Slack mrkdwn\n\nSlack's custom `mrkdwn` syntax is not standard Markdown. First identify the receiving field; the same punctuation can mean something different on another Slack surface.\n\n## Choose the Rendering System\n\n| System | Common surfaces | Example |\n|---|---|---|\n| Slack `mrkdwn` | Top-level message `text` (default), Block Kit text objects with `type: \"mrkdwn\"`, composer/classic unfurl blocks, legacy attachment fields enabled by `mrkdwn_in` | `*bold* <https://example.com\\|link>` |\n| Standard Markdown | `markdown` block; `markdown_text` chat method arguments; Work Object string fields/comments with `format: \"markdown\"`; Work Object partial-view messages with `message_format: \"markdown\"` | `**bold** [link](https://example.com)` |\n| Structured `rich_text` | Slack's WYSIWYG/user-message representation and `rich_text_input` values | Explicit nested JSON elements and style objects |\n| `plain_text` | Labels, buttons, placeholders, view titles, and any text object that must render literally | No formatting syntax |\n\nDo not translate by punctuation alone. For example, `*bold*` in mrkdwn is italic in standard Markdown. A `rich_text` block does not parse either syntax; construct its elements explicitly.\n\n## Standard Markdown Surfaces\n\n### Markdown Block\n\n```json\n{\n  \"type\": \"markdown\",\n  \"text\": \"## Result\\n\\n**Complete** — see [details](https://example.com).\"\n}\n```\n\nSlack's `markdown` block explicitly documents support for:\n\n- bold, italic, nested bold/italic, and strikethrough\n- ordered and unordered lists\n- links, block quotes, inline code, and fenced code blocks\n- language-tagged fenced code blocks with syntax highlighting\n- headings, horizontal dividers, tables, and task lists\n- images, translated to hyperlink text using the image alt text\n- backslash escaping of documented special characters\n\nThe current block reference says all heading levels render at the same size, while Slack's March 6, 2026 changelog says variable-sized headers are being rolled out. Treat heading size as rollout- and client-dependent rather than relying on a specific visual hierarchy until the references converge. A single input block may translate into multiple output blocks. The cumulative `text` limit across all `markdown` blocks in one payload is 12,000 characters. A supplied `block_id` is ignored and not retained.\n\n### `markdown_text` Chat Arguments\n\nThe following current Web API methods accept a standard-Markdown `markdown_text` argument with a 12,000-character limit:\n\n| Methods | Combination rules |\n|---|---|\n| `chat.postMessage`, `chat.postEphemeral`, `chat.scheduleMessage`, `chat.update` | Do not combine `markdown_text` with `blocks` or `text`; Slack returns `markdown_text_conflict` |\n| `chat.startStream`, `chat.appendStream`, `chat.stopStream` | Accept Markdown during a stream; `chat.stopStream` can also append final `blocks`, rendered after streamed Markdown/chunks |\n\nStreaming methods also accept `chunks`. In the current method references, a Markdown chunk is:\n\n```json\n{ \"type\": \"markdown_text\", \"text\": \"**Streaming** response\" }\n```\n\n`chunks` can also carry task updates, plan updates, and block chunks. Consult the individual streaming method reference for the exact request fields and current limits. Link unfurling is disabled in streaming messages.\n\n### Work Objects\n\nWork Objects do not use mrkdwn for their metadata string formatting:\n\n```json\n{\n  \"type\": \"string\",\n  \"value\": \"**Blocked** — see [runbook](https://example.com/runbook)\",\n  \"format\": \"markdown\"\n}\n```\n\n- A Work Object `fields` or `custom_fields` property of type `string` can set `format: \"markdown\"`. This is incompatible with that field's `icon` or `link` properties.\n- Work Object comments can provide `{ \"value\": \"...\", \"format\": \"markdown\" }`; comments may alternatively provide structured rich-text blocks.\n- A custom partial-access message can set `message_format: \"markdown\"` for its `custom_message`.\n- To reference a Work Object inside `rich_text`, use a structured `work_object_mention` element (including `entity_id`, `app_id`, `text`, and `url`), not a made-up mrkdwn token.\n- Block Kit text objects embedded in composer or classic link unfurls still follow their own `mrkdwn`/`plain_text` rules.\n\n## mrkdwn Syntax\n\n| Format | Syntax | Notes |\n|---|---|---|\n| Bold | `*bold*` | Not `**bold**` |\n| Italic | `_italic_` | Not `*italic*` |\n| Strikethrough | `~strikethrough~` | Not `~~strikethrough~~` |\n| Inline code | `` `code` `` | Other formatting is disabled inside |\n| Code block | Triple backticks around the text | No documented language-tag highlighting in mrkdwn |\n| Block quote | `>quoted text` | Put `>` at the start of each quoted line |\n| Link | `<https://example.com\\|display text>` | Not `[text](url)` |\n| Emoji | `:emoji_name:` or Unicode | Retrieved messages use colon form |\n| Newline | `\\n` in a string | Produces a line break |\n| List-like text | `- item` / `1. item` plus newlines | mrkdwn has no list syntax; these are text conventions |\n\nHeadings are not mrkdwn syntax. Use a `header` block, a standard-Markdown `markdown` block, or structured rich text as appropriate.\n\nFor complex combinations, true lists, or user-authored formatting, prefer structured `rich_text` instead of relying on undocumented marker nesting.\n\n## Links and Unfurls\n\n```text\nhttps://example.com\n<https://example.com>\n<https://example.com|Display text>\n<mailto:user@example.com|Email user>\n```\n\nRaw URLs in mrkdwn are normally auto-transformed into links. URLs containing spaces break parsing; remove or URL-encode the spaces. When messages are retrieved, Slack returns auto-transformed URLs in angle-bracket form, sometimes with an explicit label.\n\nSlack normally unfurls links posted by users and apps, including media links in Block Kit blocks. For publishing methods that expose these parameters:\n\n| Parameter | Controls |\n|---|---|\n| `unfurl_links` | Primarily text-based content |\n| `unfurl_media` | Media such as images, video, and audio |\n\nSet both to `false` to suppress all link previews. For messages containing LLM-generated URLs, disable unfurls by default with both `unfurl_links: false` and `unfurl_media: false`: Slack warns that its outbound preview request can complete prompt-injection data exfiltration. If previews are required, allow-list trusted external domains and reject or report URLs outside that list. Slack does not unfurl a manually labeled link when the label is a complete substring of the URL after removing the protocol (for example, `<http://example.com|example.com>`). Streaming messages do not unfurl links.\n\nCustom app unfurls use the renderer of each receiving field. Composer preview `elements` can contain an object with `type: \"mrkdwn\"`; blocks within the unfurl use their normal text-object rules. Exception: `chat.unfurl` does not currently support rich-text blocks and may return `invalid_blocks` for an otherwise valid Block Kit payload containing a rich-text section element. A `chat.unfurl` `user_auth_message` supports simple Slack formatting, while `user_auth_blocks` supplies a Block Kit alternative. Work Object entity metadata remains a separate standard-Markdown case as described above.\n\n## Mentions and References\n\n### Manual, Stable Syntax\n\n```text\n<@U0123ABC456>          user mention\n<#C0123ABC456>          conversation link\n<!subteam^SAZ94GDB8>    user group mention\n<!here>                 active channel members\n<!channel>              all channel members\n<!everyone>             everyone in #general (non-guest workspace members)\n```\n\nAn app-published user mention notifies that user. An app-published user group mention notifies the group. Special mentions can notify many people and should be used sparingly.\n\nUse IDs rather than names. User, conversation, and user-group names can change; their IDs are stable. A user who cannot access a referenced private channel sees an unclickable `private channel` label.\n\nThe current `chat.postMessage` reference says `link_names` finds and links **user groups** and no longer supports individual users. Do not depend on name auto-parsing for users, conversations, or special mentions. Use the explicit forms above.\n\n## Date Formatting\n\nSlack localizes app-published dates to the timezone setting of the viewer's **device**, not the timezone preference in their Slack client.\n\n```text\n<!date^{unix_timestamp}^{token_string}^{optional_link}|{fallback_text}>\n```\n\n| Token | Example behavior |\n|---|---|\n| `{date_num}` | `2014-02-18`, with leading zeros |\n| `{date}` | `February 18th, 2014` |\n| `{date_short}` | `Feb 18, 2014` |\n| `{date_long}` | `Tuesday, February 18th, 2014` |\n| `{date_pretty}` | `{date}`, but uses yesterday/today/tomorrow where appropriate |\n| `{date_short_pretty}` | `{date_short}`, but uses yesterday/today/tomorrow |\n| `{date_long_pretty}` | `{date_long}`, but uses yesterday/today/tomorrow |\n| `{time}` | Viewer preference: `6:39 AM` or `18:39` |\n| `{time_secs}` | Viewer preference: `6:39:42 AM` or `18:39:42` |\n| `{ago}` | Human-readable elapsed time such as `3 minutes ago` |\n\n`{date}`, `{date_short}`, and `{date_long}` omit the year when the date is less than six months in the past or future. The optional third `^`-separated value must be a fully qualified URL and makes the rendered date clickable.\n\nFallback text is required for older clients. Include a timezone in it because the fallback cannot be localized.\n\n```text\n<!date^1392734382^Posted {date_num} {time_secs}|Posted 2014-02-18 6:39:42 AM PST>\n<!date^1392734382^{date_short}^https://example.com/|Feb 18, 2014 PST>\n```\n\nSlack returns the original `<!date...>` string when messages are retrieved.\n\n## Escaping\n\nSlack reserves exactly three characters for special parsing. When they are data rather than deliberate control syntax, encode them as:\n\n| Character | Entity |\n|---|---|\n| `&` | `&amp;` |\n| `<` | `&lt;` |\n| `>` | `&gt;` |\n\nDo not HTML-encode the whole string: Slack only decodes these three documented entities. Escape `&` first, then `<` and `>`, to avoid re-encoding the ampersand you just introduced. JSON/string escaping is a separate concern.\n\nEscape untrusted text before placing it in a mrkdwn-capable field. Otherwise it can introduce links, manual mention tokens, or date controls. Prefer `plain_text` when no formatting is needed.\n\n## Text Objects\n\n```json\n[\n  { \"type\": \"mrkdwn\", \"text\": \"*bold* and _italic_\", \"verbatim\": true },\n  { \"type\": \"plain_text\", \"text\": \"No formatting\", \"emoji\": true }\n]\n```\n\nThe generic text object allows 1–3,000 characters. A containing block or element may impose a smaller limit; for example, section `fields` allow up to 10 objects of 2,000 characters each.\n\n- `verbatim` is valid only for `mrkdwn`.\n- `emoji` is valid only for `plain_text` and controls whether Slack escapes recognized emoji into colon format. It does not enable mrkdwn.\n\n### `verbatim`\n\n| Value | Behavior |\n|---|---|\n| `false` (default) | Preprocesses plain content: raw URLs become links, conversation names may be linked, and certain mentions may be parsed |\n| `true` | Skips that preprocessing, while still processing mrkdwn and explicit manual constructs such as `<@U…>` or `<url\\|label>` |\n\nUse `verbatim: true` when content contains raw `@`, `#`, or URLs that should not ","tagline":"Proactively apply when generating any Slack text content, message text fields, Block Kit text objects, standard Markdown for Slack, or Work Object text.
