# Uber Webhooks

## When to Use This Skill

* How do I receive Uber Eats webhooks?
* How do I verify Uber webhook signatures?
* Why is my `X-Uber-Signature` verification failing?
* How do I handle `orders.notification` or `orders.cancel` events?
* Setting up an Uber Eats webhook receiver in Express, Next.js, or FastAPI

## Verification (core)

Uber Eats signs the raw request body with HMAC-SHA256 keyed on your app's
client secret and sends the digest as a lowercased hex string in the
`X-Uber-Signature` header (no `sha256=` prefix). Pass the raw body bytes,
compute the digest, and compare timing-safe.

Node:

```javascript
const crypto = require('crypto');

function verifyUberWebhook(rawBody, signatureHeader, clientSecret) {
  if (!signatureHeader) return false;
  const expected = crypto
    .createHmac('sha256', clientSecret)
    .update(rawBody)
    .digest('hex');
  try {
    return crypto.timingSafeEqual(
      Buffer.from(signatureHeader, 'hex'),
      Buffer.from(expected, 'hex')
    );
  } catch {
    return false;
  }
}

```

Python:

```python
import hmac, hashlib

def verify_uber_webhook(raw_body: bytes, signature_header: str, client_secret: str) -> bool:
    if not signature_header:
        return False
    expected = hmac.new(client_secret.encode(), raw_body, hashlib.sha256).hexdigest()
    return hmac.compare_digest(signature_header, expected)

```

## Common Event Types

The event type is in the JSON body's `event_type` field (not a header).

| Event | Description |
| --- | --- |
| `orders.notification` | New order created |
| `orders.cancel` | Order cancelled (non-v1.0.0 stores) |
| `orders.failure` | Order cancelled (API v1.0.0 only) |
| `orders.release` | Fast order release: courier reached the geo-fence |
| `orders.scheduled.notification` | Scheduled order created (API v1.0.0 only) |
| `order.fulfillment_issues.resolved` | Customer confirmed a fulfillment change |
| `store.provisioned` | Store granted app access |
| `store.deprovisioned` | Store access removed |
| `store.status.changed` | Store online status changed |

> For the full event reference, see [Uber Eats Webhooks](https://developer.uber.com/docs/eats/guides/webhooks).

## Important Headers

| Header | Description |
| --- | --- |
| `X-Uber-Signature` | Lowercased hex HMAC-SHA256 of the raw body, keyed with client secret |
| `X-Uber-Delivery` | Unique delivery/attempt identifier |

## Acknowledging Deliveries

Respond with HTTP `200` and an empty body to acknowledge. Uber retries on
`500`/`502`/`503`/`504`, timeouts, and network errors with backoff (10s, 30s,
60s, 120s, then exponential, up to ~7 attempts).

## Environment Variables

```bash
UBER_CLIENT_SECRET=your_app_client_secret   # From the Uber Developer Dashboard

```

> Note: Uber Direct (Deliveries) webhooks use a different scheme — a dedicated
> per-webhook Signing Key (not the client secret) sent as `x-uber-signature` /
> `x-postmates-signature`. See [references/verification.md](https://github.com/hookdeck/webhook-skills/blob/main/skills/uber-webhooks/references/verification.md).

## Local Development

```bash
# Start tunnel (no account needed)
npx hookdeck-cli listen 3000 uber --path /webhooks/uber

```
