Webhooks API

Webhooks are planned, not yet shipped. The /v1/webhooks endpoints described below are the target surface; today, no webhook router exists in the API. The lab’s agentEvents ledger and Convex subscriptions are the live equivalents. Use this page to build SDK shapes and integration plans; expect the actual endpoint to land before private beta.

Webhooks let you receive HTTP callbacks when events occur in your lab. Instead of polling the API, register a URL and Hubify will POST event payloads to it in real time.

Payload Format

All webhook payloads follow a consistent structure:

  "type": "experiment.completed",
  "createdAt": 1713100800000,
  "labId": "j57a8k9m2n3p4q5r",
  "data": {
    "_id": "exp_abc123",
    "experimentId": "EXP-054",
    "title": "MCMC Chain -- Planck 2018 + BAO",
    "status": "pass",
    "runTimeSeconds": 3847,
    "completedAt": 1713100800000
  }
}

string

required

Unique event ID. Use for idempotency.

type

string

required

Event type (e.g., experiment.completed).

createdAt

number

required

Event timestamp in milliseconds.

labId

string

required

Lab the event belongs to.

data

object

required

Event-specific payload. Contains the relevant resource object.

Signature Verification

Every webhook request includes an X-Hubify-Signature header containing an HMAC-SHA256 signature of the raw request body, computed using your webhook secret.

import crypto from "crypto";

function verifyWebhook(
  body: string,
  signature: string,
  secret: string
): boolean {
  const expected = crypto
    .createHmac("sha256", secret)
    .update(body)
    .digest("hex");
  return crypto.timingSafeEqual(
    Buffer.from(signature),
    Buffer.from(expected)
  );
}

// In your webhook handler:
app.post("/webhooks/hubify", (req, res) => {
  const signature = req.headers["x-hubify-signature"] as string;
  if (!verifyWebhook(req.rawBody, signature, WEBHOOK_SECRET)) {
    return res.status(401).send("Invalid signature");
  }

  const event = JSON.parse(req.rawBody);
  console.log("Received " + event.type + ":", event.data);
  res.status(200).send("OK");
});

import hmac
import hashlib

def verify_webhook(body: bytes, signature: str, secret: str) -> bool:
    expected = hmac.new(
        secret.encode(),
        body,
        hashlib.sha256
    ).hexdigest()
    return hmac.compare_digest(signature, expected)

Retry Policy

Failed webhook deliveries are retried with exponential backoff:

Attempt	Delay
1	Immediate
2	30 seconds
3	2 minutes
4	10 minutes
5	1 hour
6	6 hours

After 6 failed attempts, the webhook is marked as failing and the Captain receives a notification. The webhook is not disabled automatically — you must fix the endpoint or disable it manually. A delivery is considered failed if:

The endpoint returns a non-2xx status code
The request times out after 30 seconds
The endpoint is unreachable (DNS failure, connection refused)
