description: Connect a Grok Bot routine to your own app - webhook wake-ups with ids only, burst grouping without lost messages, a key-protected agent API Grok calls back into, owner-in-the-loop replies, metered time and gated email. Use when an app (client portal, inbox, helpdesk) must notify Grok Bot and let it act through your API.

# Grok Bot routines + your app: wake-ups, agent API, owner in the loop

A pattern that works in production for a client portal. Clients write in your app, Grok Bot is woken, and Grok reports to the owner and acts through your API. It's live-tested end to end. The lessons at the bottom are the expensive ones.

## How Grok Bot routines take webhooks (from the Grok Bot routines help page)

- Ask Grok Bot to add a **webhook trigger** to a routine. On desktop, the routine shows a **POST to** URL and a **key**.
- Send `POST` with header `Authorization: Bearer <key>` and an optional JSON body. Grok receives the body together with the routine's instruction.
- **200 means a run started, not that it finished.** Any other status means no run started. Results show up in Grok's chat or through whatever it does via your API.
- Limits: 200 runs per hour per routine, 300 per hour in total. A rate-limited run is **not retried**. Every run uses usage.
- The docs don't say anything about deduplication or payload size, so keep payloads small and your own design idempotent.

## Architecture

```
client writes ──► your app SAVES the message ──► POST routine webhook (ids only) ──► Grok run starts
                                                                                        │
owner ◄── Grok chat: "Project X — Acme sent: '…' What do you want me to do?" ◄────────┘
owner: "reply: …" ──► Grok ──► POST your agent API {op:"reply"} ──► client sees it
```

- **Save first, wake second.** A failed or rate-limited wake must never lose a message.
- **The wake carries ids only, never message text or personal data.** Grok reads the content through your API with its own key.
- Your API is **self-describing** (`op=help`) and returns the live rules, so you can change behaviour without re-briefing Grok.

## Two keys, two directions

| Direction | Key | Where it lives |
|---|---|---|
| Grok → your API | You generate it (`crypto.randomBytes(36)`) | Your server stores **only its sha256** in env. Grok keeps the plaintext in its encrypted env. |
| Your app → Grok routine | Grok gives it to you with the webhook URL | Your server env (secret) |

Don't paste keys into any chat. Hand them over in a file, load the file, then delete it. Compare keys with `timingSafeEqual` on sha256 digests:

```ts
const expected = (process.env.AGENT_TOKEN_SHA256 || "").trim();
const h = req.headers.authorization || "";
const ok = /^[a-f0-9]{64}$/.test(expected) && h.startsWith("Bearer ") && h.length < 300 &&
  crypto.timingSafeEqual(crypto.createHash("sha256").update(h.slice(7)).digest(), Buffer.from(expected, "hex"));
```

## Wake payload (one Grok, many projects)

If one Grok Bot serves several of your projects, name the project in every call:

```json
{ "project": "acme-client-portal", "projectName": "Acme client portal", "site": "https://example.com",
  "api": "https://example.com/api/agent/portal", "event": "portal_client_message", "kind": "message",
  "eventId": "<message id>", "clientId": "c_123", "company": "Example Co", "at": "2026-01-01T12:00:00Z",
  "instructions": "Read the thread with GET {api}?op=client&clientId=…, tell the owner what the client wrote, send only the reply the owner gives you." }
```

Use a distinct `event` and `kind` for special requests (for example `portal_task_request`), with their own instruction.

## Bursts without lost messages

People send three messages in 20 seconds. Wake Grok once, but never leave a message unannounced:

1. The first message wakes Grok **immediately**. Record `lastSentAt`.
2. A message inside the window (for example 2 minutes) schedules **one** follow-up wake for the end of the window. Record `trailingAt`. On Vercel, use `waitUntil` so the timer survives the response.
3. Further messages in the window see `trailingAt` and do nothing more.
4. A successful wake clears `pendingSince` and `trailingAt`. A non-200 response records the status, and the inbox still lists the client (the safety net).

```ts
import { waitUntil } from "@vercel/functions";
const due = Date.parse(state.lastSentAt ?? "") + WINDOW_MS;
if (due > Date.now()) {
  if (!state.trailingAt || Date.parse(state.trailingAt) < Date.now()) {
    await save({ trailingAt: new Date(due).toISOString(), pendingSince: state.pendingSince ?? now() });
    waitUntil(new Promise(r => setTimeout(r, due - Date.now())).then(() => sendWake(id)));
  }
  return "scheduled";
}
return (await sendWake(id)) ? "started" : "failed";
```

Grok reads the **whole thread** on each run, so one wake covers a burst. That's why the follow-up is enough.

## Agent API shape (what Grok calls)

- `GET ?op=help`: project, rules, reply mode, every op. Grok calls this first.
- `GET ?op=inbox`: clients whose newest messages came after the last team reply.
- `GET ?op=client&clientId=`: scope, thread, tasks, this month's usage plus every time entry.
- `POST {op:"reply"}`, `task_create`, `task_update`, `usage_log`, `email_client`.
- Stable error codes (`allowance_reached`, `invalid_minutes`, `email_demo_only` …) and a 401 for a bad key. Grok handles codes far better than prose.

## Owner in the loop: put approval where the owner talks to Grok

We first saved Grok's replies as **drafts** with Approve and Send buttons inside the client portal. The owner found it confusing, because the owner was talking to Grok in Grok's chat, not in the portal. What works:

- **Messenger pattern:** Grok tells the owner in its chat exactly what the client wrote and asks what to do. It sends only the reply the owner gives (spelling fixes OK), and never writes replies on its own.
- Put this rule in three places: the wake `instructions`, the `op=help` response, and the routine brief.
- The client portal shows **only the client view**, even when the viewer is also signed in as admin.

## Metering paid time

- Each client has a monthly allowance (for example 120 minutes). The meter counts **all** work: the bot's own (`workedBy: "grok"`) and the owner's, reported at check-in (`workedBy: "team"`).
- **Realistic entries only:** 5 or 10 minutes, otherwise steps of 15. Enforce this on the server.
- Refuse entries past the allowance with **409 `allowance_reached`**. The bot must stop and tell the owner, never keep working unpaid.
- Pass `taskId` with time, so each task shows its time, plus created and completed timestamps in the client's time zone.

## Email from the bot: gate it

- An allowlist switch (for example "demo clients only") until the owner approves real clients.
- A per-client daily cap, plain-text body escaped into your branded template, and a link back to the app.
- Log every send, including who, which client, the subject, and whether delivery succeeded.

## Lessons that cost real time

1. **Admin plus client session in one browser.** The owner tested the client portal while also signed in as admin, so their messages were saved as "team", and the inbox (client messages only) stayed empty. Inside a client's own portal, write *as the client* no matter what other session exists.
2. **Public sample pages must never write, and must say so.** Our sample said "Received" while sending nothing. Label it plainly ("Sample page: not sent").
3. **Tell the truth about delivery.** Show "your team has been notified" only on a 200 from the routine. Otherwise say it's queued.
4. **A test must never wake the real routine.** Blank the webhook env inside tests and mock `fetch`.
5. **Env changes need a redeploy.** Adding the webhook URL and key does nothing until the next deploy.
6. **Test with a real demo record.** Create one demo client in the real database, with no billing and a login to your own inbox, and keep a `--remove` script that deletes it and everything attached. Use temporary QA clients for automated tests and delete them by id afterward.
7. **Node `fetch` silently ignores a custom `Host` header.** Use curl when testing host-based routing locally.
8. **Read env files carefully.** Values can carry a literal trailing `\n`. Trim before signing anything.

## Health endpoint

A read-only `GET /health`, protected by a secret, returns `ALL_SYSTEMS_GO | DEGRADED | CRITICAL` with these checks:

- the agent key hash is set
- the webhook URL and key are set
- the reply mode
- storage is reachable, with message, task and pending-wake counts
- the last wake results
- a meter self-test

It reports `DEGRADED` until the webhook is configured. That's the fastest way to see why Grok "isn't waking up".

## Tested

- **Live on production:** a client message woke the routine (200), and Grok replied through the agent API about 40 seconds later. A 3-message burst got one wake, and Grok answered all of them.
- **Locally:** 26/26 end-to-end checks covering auth, inbox, context, replies, tasks, the meter thresholds and refusals, unknown client, and health. A mocked-webhook test confirmed one immediate wake plus one follow-up per burst, with pending cleared.
- **Not covered:** behaviour when the routine itself is rate-limited platform-wide (a documented known issue). Rely on the inbox safety net for that case.
