# Revolut Webhooks

## When to Use This Skill

- How do I receive Revolut Merchant webhooks?
- How do I verify Revolut webhook signatures (the `Revolut-Signature` header)?
- How do I handle `ORDER_COMPLETED` or `ORDER_PAYMENT_DECLINED` events?
- Why is my Revolut webhook signature verification failing?
- How do I set up a Revolut webhook endpoint via the Merchant API?

## Verification (core)

Revolut signs each webhook with **HMAC-SHA256** (hex-encoded) using your
webhook **signing secret** (`wsk_…`, returned when you create the webhook via
the Merchant API). There is no official SDK webhook helper, so verify manually.

The signed payload is `v1.{Revolut-Request-Timestamp}.{raw body}` —
period-separated, using the **raw** request body (re-serialized JSON breaks the
signature). The `Revolut-Signature` header holds `v1=<hex>` and may carry
multiple comma-separated signatures during secret rotation — accept if **any**
matches.

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

function verifyRevolutSignature(rawBody, timestamp, signatureHeader, secret) {
  if (!timestamp || !signatureHeader) return false;

  // Reject stale timestamps (± 5 min). Header is a UNIX timestamp in ms.
  const ts = Number(timestamp);
  const tsMs = timestamp.length <= 10 ? ts * 1000 : ts; // tolerate seconds or ms
  if (!Number.isFinite(ts) || Math.abs(Date.now() - tsMs) > 5 * 60 * 1000) return false;

  const expected = 'v1=' + crypto
    .createHmac('sha256', secret)
    .update(`v1.${timestamp}.${rawBody}`)
    .digest('hex');

  // Header may hold multiple signatures during rotation — accept any match.
  return signatureHeader.split(',').some((sig) => {
    const a = Buffer.from(sig.trim());
    const b = Buffer.from(expected);
    return a.length === b.length && crypto.timingSafeEqual(a, b);
  });
}
```

## Common Event Types

| Event | Description |
|-------|-------------|
| `ORDER_COMPLETED` | Order fully paid and completed |
| `ORDER_AUTHORISED` | Payment authorised (funds held, not yet captured) |
| `ORDER_CANCELLED` | Order cancelled |
| `ORDER_PAYMENT_AUTHENTICATED` | Customer completed payment authentication (e.g. 3DS) |
| `ORDER_PAYMENT_DECLINED` | Payment declined by the issuer or Revolut |
| `ORDER_PAYMENT_FAILED` | Payment failed due to a processing error |

Payload shape (order events):

```json
{
  "event": "ORDER_COMPLETED",
  "order_id": "6516e61c-d279-a454-a837-bc52ce55ed49",
  "merchant_order_ext_ref": "Order #2937"
}
```

## Environment Variables

```bash
REVOLUT_SIGNING_SECRET=wsk_xxxxx   # Signing secret returned when the webhook is created
```

## Local Development

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

## Recommended: webhook-handler-patterns

We recommend installing the [webhook-handler-patterns](https://github.com/hookdeck/webhook-skills/tree/main/skills/webhook-handler-patterns) skill alongside this one for handler sequence, idempotency, error handling, and retry logic. Key references (open on GitHub):

- [Handler sequence](https://github.com/hookdeck/webhook-skills/blob/main/skills/webhook-handler-patterns/references/handler-sequence.md) — Verify first, parse second, handle idempotently third
- [Idempotency](https://github.com/hookdeck/webhook-skills/blob/main/skills/webhook-handler-patterns/references/idempotency.md) — Prevent duplicate processing (Revolut retries 3 more times at 10-minute intervals)
- [Error handling](https://github.com/hookdeck/webhook-skills/blob/main/skills/webhook-handler-patterns/references/error-handling.md) — Return codes, logging, dead letter queues
- [Retry logic](https://github.com/hookdeck/webhook-skills/blob/main/skills/webhook-handler-patterns/references/retry-logic.md) — Provider retry schedules, backoff patterns
