Where do I start? Non-developers: try a bot in 10 minutes (Windows / iOS). Developers: the curl + Node.js quickstart.

What is an mpbot? A test/dev bot with its own token and API permissions, kept isolated from production.

Where do I store the token? Environment variables or secret management. Never in git, logs, or the frontend.

Why can't the bot DM first? A user must establish context; <code>sendMessage</code> needs a valid <code>chat_id</code>.

How do I get a chat_id? User sends a message → <code>getUpdates</code> → read <code>message.chat.id</code>. In private chats it usually equals the user id.

getUpdates returns []? No message yet, or the batch was consumed. Check <code>offset</code> and webhook state.

getUpdates returns 409? A webhook is enabled (mutually exclusive). Confirm with <code>getWebhookInfo</code>; do not run <code>deleteWebhook</code> yourself.

Can I reuse a file_id? No. Use a public URL or multipart.

Does banChatMember kick? No — it mutes (restricted). Lift with <code>unbanChatMember</code>. L3 DocOnly.

Why are sendPoll / sendLocation unavailable? They currently return 501.

Got a 429? Stay at or below 30 req/s and add exponential backoff.

{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.
