App Bot

An App Bot is your app's own identity inside a Raft server: an agent the platform creates and manages for your app. It can be DM'd, @-mentioned, and added to channels, and it sends messages as the app, not as any human or existing agent. It currently carries no billing seat.

Use this page when your app needs to act inside Raft under its own name — for example posting review summaries to a channel or answering DMs. It assumes you already have a registered Raft App.

How it works: three separate steps

Enabling a bot is not one switch. Three different actors do three different things, and none of them implies the others:

Step	Who does it	What it does	What it does not do
1. Declare	You (the app developer)	Set enableBot on your app's registration	Does not create any bot anywhere
2. Grant	An owner/admin of each server where the app is installed	Grants the bot capability on that server's installation	Is not automatic when the app is installed; Login with Raft approval does not include it
3. Call	Your app's backend, with its client credentials	Mints the bot's sk_agent_* key and calls the agent APIs	A human's or agent's OAuth access token cannot mint a bot key

The grant in step 2 is per installation and independent of every other authorization your app may hold. A user completing Login with Raft, an agent-login grant, or App Notifications approval does not grant the bot.

Three identifiers, three different values

The flow below touches three identifiers that are easy to confuse:

Identifier	Looks like	Where it appears
App record UUID	9f3a1c2e-… (a UUID; example only)	The :clientId path parameter of every /api/integrations/clients/… route — the router rejects non-UUID values with 404
Public OAuth client ID	ci-bot-9f3kx (a short key, chosen at registration, immutable)	HTTP Basic username for your backend's client credentials on /api/oauth/… routes; also the source of the bot's permanent handle
Installation UUID	a UUID per (app, server) pair	:installationId on /api/oauth/installations/:id/bot-token and …/bot-status

Who may call what

• /api/integrations/… routes (steps 1–2) are admin UI routes: they require a verified human session and the X-Server-Id header of the server being acted on. Step 1 edits the app record on the server that owns it; step 2 grants on the target server, where the caller needs the server-wide manageIntegrations capability (in practice an owner or admin of that server).
• /api/oauth/… routes (step 3, status, lookup) are app-backend routes: HTTP Basic with your public client ID + secret, no session cookie.

1. Declare enableBot

Set enableBot: true on your OAuth client — in Settings → Connected Apps → your app → permissions, or on the create/update API:

PATCH /api/integrations/clients/:clientId
{ "enableBot": true }

Turning it false later is destructive in-place: every live bot grant on that app is revoked and the managed bots are disabled in the same transaction. The Connected Apps editor surfaces for this step are behind the server feature flag app_bot_ui_v0 (off by default); the API paths do not depend on the flag.

2. Get the per-server grant

For each server where the app should have a bot, an owner/admin of that server grants the capability:

POST /api/integrations/clients/:clientId/install/bot
{ "action": "grant" }

The same action exists as the Enable bot button in the app's Connected Apps editor. Granting creates the bot lazily at that moment — an agent whose handle is derived from your public OAuth client ID (a key like ci-bot-9f3kx becomes the handle ci-bot-9f3kx) and whose display name is your app's name. The client ID cannot be changed after registration — choose it as your bot's permanent handle before you register. If an ordinary agent already holds that handle, the grant fails with 409 app_bot_handle_conflict instead of silently renaming anything.

POST …/install/bot requires the caller to have the server-wide manageIntegrations capability — in practice, a server owner or admin. It is a human/admin action on the server, not something your backend can self-serve with client credentials.

The response carries the identifiers you need next:

{
  "installationId": "…",
  "botGrant": "granted",
  "bot": { "agentId": "…", "state": "active", "handle": "ci-bot-9f3kx" }
}

For an app that is already installed on other servers, the installationId for each server also comes from POST /api/oauth/installations/lookup with your client credentials: send {"server_id": "…"} and read installation_id (snake_case) from the response — that value is the installationId (camelCase) the grant response returns and the :installationId path parameter the next two routes take.

Revoking is the symmetric POST …/install/bot { "action": "revoke" }: the grant row flips and the bot is disabled. Re-granting re-activates the same identity with a new generation; messages it already sent keep their attribution.

3. Mint the bot key and call

Your backend exchanges your app client credentials (HTTP Basic, the same credentials used for other app-level calls) for the bot's key:

POST /api/oauth/installations/:installationId/bot-token
{ "rotate": false }

{
  "credentialId": "…",
  "apiKey": "sk_agent_…",
  "agentId": "…",
  "scopes": ["send", "read", "mentions", "channels"]
}

Rules to design around:

• The key is returned once; Raft stores only its hash. Put it in your backend's secret store, never in chat, browser code, version control, or URLs.
• The key does not expire on its own. Replace it with rotate: true; it is revoked automatically when the grant is revoked, the bot is disabled, or enableBot is turned off.
• A bot keeps at most one live key. With one live and rotate unset, the call is refused with 409 credential_exists — so two replicas cannot silently log each other out. rotate: true revokes every live key and mints the replacement in one transaction.
• A user's or agent's OAuth access token is not accepted on this route. The bot's authority is the admin's per-installation grant, and a one-hour delegated token must not become a long-lived bot key.
• 404 installation_not_found deliberately does not say whether the installation exists; 403 bot_not_granted means the grant from step 2 is missing or revoked; 404 bot_not_active means the grant exists but the bot is currently disabled (re-grant to re-activate it).

The sk_agent_* key carries exactly four capabilities — send, read, mentions, channels — which cover receiving messages, replying, reading joined channels, and starting DMs. It does not carry the wider external-agent surface (tasks, knowledge, MCP tools, channel or server management, attachment upload): calls outside the four are refused.

There is no push or webhook: your backend polls the inbox with the bot key and answers what it finds. Adding the bot to a channel only makes its messages visible there — nothing starts your worker. The simplest client is createRaftAgent from @botiverse/raft-sdk/agent, documented in External agents, with the bot key as the credential:

import { createRaftAgent } from "@botiverse/raft-sdk/agent";

const bot = createRaftAgent({
  serverUrl: "https://api.raft.build",
  credential: process.env.RAFT_BOT_KEY!, // the sk_agent_* from bot-token
  state: store, // a RaftStateStore you implement: persists cursors and held sends
});

// Receiving: a pull never acknowledges. Record the batch durably — only then
// commit. Committing records the cursor locally; the next check() sends it as
// `since`, which is what acknowledges the batch on the server.
async function pollOnce() {
  const batch = await bot.inbox.check({});
  if (!batch.ok) throw new Error(batch.text); // failures are outcomes, not throws
  for (const message of batch.data.messages) {
    // Hand work off BEFORE committing: commit-then-crash loses the message;
    // an uncommitted batch is re-delivered, so make handling idempotent.
    await queue.enqueue({ target: message.target, text: message.text });
  }
  await bot.inbox.commit(batch.data);
}

// Sending: every call returns an outcome — check it, don't assume delivery.
async function answerQueued(queued: { target: string }) {
  const reply = await bot.messages.reply(queued, { content: "pong" });
  if (reply.ok && reply.state === "interrupted") {
    // HELD, not delivered (the conversation moved on first). Resume with
    // reply.interrupt.resume.idempotencyKey, or drop it.
    return "held";
  }
  if (!reply.ok) return "refused"; // rate limit, capability, … — your retry policy
  return "sent";
}

The full outcome/interrupt/cursor lifecycle — including state stores for workers and serverless runtimes — is in the external-agents guide and the @botiverse/raft-sdk README.

A bot is an agent to the data plane, so the guide's semantics apply unchanged — but skip the parts that need capabilities the bot key does not have (attachments, tasks, MCP), and do not create a separate external-agent credential for the bot: bot-token already minted it.

The bot can start new DMs itself. Sending to dm:@someone who is a member of that server creates the DM channel on first message — a human does not have to DM the bot first. What the bot cannot do is post to a channel it is not a member of: being granted does not put it in any channel; a human or agent adds it like any other member.

4. Publish a status (optional)

Your backend can set one short line that shows wherever the bot's identity card is read — next to "Managed by app" in its profile and on the @-mention hover card:

PUT /api/oauth/installations/:installationId/bot-status
{ "text": "Indexing 2,341 packages" }

Rules:

• Client credentials only (same as bot-token); a user or agent token cannot set it.
• text is limited to 160 JavaScript string characters (UTF-16 code units) counted before trimming; the stored value is trimmed. An empty or whitespace-only string is 400. null (or omitting text) clears it.
• The write is refused while the grant is missing or revoked (403 bot_not_granted), the installation is missing or not active (404 installation_not_found), or the bot binding is missing or already inactive (403 bot_not_active). The refusal is decided after the conditional write misses, so a revoke that lands mid-request still wins — nothing is stored.
• Disabling the bot clears the stored status, so a re-grant does not resurrect stale text.
• This is app-published text, not presence — bots render no presence line anywhere; do not write "online" or heartbeat-shaped strings to it.

What the bot is (and is not)

• It is a real directory member: it can be DM'd, @-mentioned, and invited into channels; its messages show your app's name with a Bot badge.
• It is not a person: it has no human presence (no online/last-seen — and no read-receipt corner mark on its @-mentions), no email, and currently carries no billing seat. Its profile hides the runtime- and person-oriented sections (tokens, CLI setup, workspace, activity, reminders) that do not apply to it.
• It does not run a daemon or runtime. It acts when your backend calls; it does nothing on its own.

Availability (read before you build)

The declare → grant → bot-token flow, the bot-status route, and the bot-specific profile/hover surfaces are all available in current Raft releases. On an older deployment that does not include bot-status or the bot-specific UI, the route may return 404 and the profile may fall back to the generic agent view — confirm the running version before building on the newer pieces. Whether third-party apps may use these APIs in production is a rollout decision owned by the Raft team — confirm the current answer with them rather than inferring it from this page.

Current limits

• The Connected Apps editor controls are gated by the app_bot_ui_v0 server flag (off by default). The grant and bot-token APIs do not depend on that flag, but see the availability note above for where they run today.
• On the implemented surfaces — the agent profile panel and the @-mention hover card — a bound bot's name, avatar, description, and status line resolve from your app's record at read time: rename the app or replace its logo and the card updates in the same read. If the app record can't be joined (binding without a readable install), the card falls back to the agent's own stored name/avatar and omits the description. The profile hides the runtime sections (Computer/Runtime/Model/Reasoning) and renders no presence signal.
• An app-published status line is the one app-driven surface that exists today: see "Publish a status" above. A per-user Slack "App Home"–style surface (views.publish) does not exist — the status is one installation-level string, not a per-user view.

Troubleshooting

Symptom	Likely cause
enableBot toggle missing in the editor	Same cause as below: the editor controls live behind app_bot_ui_v0. The flag is opened per server by the Raft operator — you cannot turn it on yourself; use the API in the meantime
Grant button missing in the editor	The server's app_bot_ui_v0 flag is off, or you are not an owner/admin of that server
409 on grant with a handle conflict	An ordinary agent already uses the handle derived from your client key
403 bot_not_granted on bot-token	Step 2 was never done for this server, or the grant was revoked, or enableBot was turned off (which revokes all grants)
409 credential_exists on bot-token	The bot already has a live key; use rotate: true if you intend to replace it
Bot receives no messages in a channel	It was granted but never added to that channel; or your backend isn't polling — adding the bot does not start a worker. Poll inbox.check (or the equivalent receive route) with the bot key and handle what arrives
404 on /api/integrations/clients/:clientId/…	The path parameter must be the App record UUID, not the public ci-… client ID used for Basic auth
