Turn off preview cards with <code>link_preview_options.is_disabled = true</code>. Mix media via <code>sendPhoto</code> / <code>sendVideo</code> / <code>sendAnimation</code> + <code>caption</code>. Explicit <code>entities</code> currently support <code>text_mention</code>; Markdown/HTML links use <code>parse_mode</code>.

These controls shape how bot text and media appear in chat. Field-level rules: <a href="https://core.mp.net/bots" rel="nofollow noopener noreferrer" target="_blank">core.mp.net/bots</a>.

On <code>sendMessage</code>, set <code>link_preview_options: { "is_disabled": true }</code> to skip normal link previews and also send <code>web_app</code> entry messages as plain text without a MiniApp card. Legacy <code>disable_web_page_preview: true</code> maps to the same flag when <code>link_preview_options</code> is absent.

{ "chat_id": 12345, "text": "https://example.com/path", "link_preview_options": { "is_disabled": true } }

Send image / video / GIF with <code>sendPhoto</code>, <code>sendVideo</code>, or <code>sendAnimation</code>.

Put the accompanying text in <code>caption</code> (same bubble). Clients size media to a fixed width with proportional height; long captions wrap. Exact length limits follow the official method pages.

Existing <code>file_id</code> reuse is not supported — use HTTPS URL or multipart upload.

Use <code>caption_entities</code> with <code>sendPhoto</code>, <code>sendVideo</code>, <code>sendAnimation</code> or <code>sendDocument</code>. Omit it to allow automatic mention detection. An empty array disables detection for that caption. Do not pass <code>reply_markup</code> to <code>sendDocument</code>, which rejects it with <code>400</code>.

Raw <code>@username</code> in text: when you omit <code>entities</code>, the server may auto-resolve unique usernames to mentions.

Explicit <code>entities</code> with <code>type: "text_mention"</code> + <code>user.id</code>: visible text can be any label, anchored to that user id (group member validation applies).

Today, public <code>entities</code> input supports only <code>text_mention</code>. Do not combine with <code>web_app</code> entry cards yet.

Omit <code>entities</code> to allow exact, case-sensitive <code>@username</code> matching. Pass <code>entities: []</code> to disable it. The default threshold is 100 raw mention tokens per message. A clickable mention does not necessarily send a group reminder. Only confirmed group members receive group @ reminders.

Use UTF-16 code units for <code>offset</code> and <code>length</code>. In <code>🚀 @Chen</code>, use offset 3 and length 5. For invitations, send the selected group members’ IDs as explicit entities.

<code>parse_mode</code> accepts <code>Markdown</code> or <code>HTML</code>. For Markdown-style hyperlinks use <code>[label](URL)</code> when <code>parse_mode</code> is Markdown.

{appName} in 60 seconds

This prototype demo is aware that you are reading “{title}”. It can point you back to the current article, but a production article-aware Fin contract is still follow-up work.

Prototype article-aware answer

Because you already asked about invitations, this prototype demo can add the follow-up: use the role selector before sending each invite to limit access to the teammate responsibilities.

Prototype role-limiting follow-up

This prototype demo suggests starting with your workspace profile, inviting the team members who need access, and then connecting the integrations you use.

Prototype getting-started answer

In this prototype demo, integrations are configured from workspace settings. Choose the integration, connect the account, and review the enabled permissions.

Prototype integrations answer

In this prototype demo, invite teammates from workspace settings, then choose the access each teammate needs before sending the invitation.

Prototype invite-team answer

This prototype demo does not have a scripted answer for that question yet. Try asking how to invite your team or open a source article. No production Fin API was called.

Prototype answer unavailable

I’ve got this page open. Ask me anything about it and I’ll answer from the docs.
