  Receive and verify Recurly webhooks. Use when setting up Recurly webhook
  handlers, verifying the recurly-signature header (HMAC-SHA256), securing the
  endpoint with HTTP Basic Auth, or handling subscription and billing events
  like new_subscription_notification, updated_subscription_notification,
  successful_payment_notification, and failed_payment_notification.

# Recurly Webhooks

## When to Use This Skill

- How do I receive Recurly webhooks?
- How do I verify the Recurly `recurly-signature` header?
- How do I secure a Recurly webhook endpoint with HTTP Basic Auth?
- How do I handle `new_subscription_notification` or `successful_payment_notification`?
- Why is my Recurly webhook signature verification failing?

## How Recurly Secures Webhooks

Recurly webhooks are secured with up to three layers. Use all that apply:

1. **Signature (JSON payloads only).** Recurly signs JSON notifications and sends
   the signature in a `recurly-signature` header. This is the primary integrity
   check — always verify it. (Legacy **XML** payloads are **not** signed.)
2. **HTTP Basic Auth.** Configure a username/password on the endpoint in Recurly;
   Recurly sends them in the `Authorization` header on every request.
3. **IP allowlist.** Accept requests only from Recurly's published IP ranges.

Prefer the **JSON** payload format so you get signature verification. The
official Recurly SDK (`recurly`) is an API client and does **not** ship a webhook
verification helper, so verify the signature manually with HMAC-SHA256.

## Verification (core)

The `recurly-signature` header is a Unix timestamp (ms) followed by one or more
**hex** HMAC-SHA256 signatures, comma-separated:

```
recurly-signature: 1659641851000,a8c8524a0cdd99e3...,cafe677a2e6fa177...
```

Signed message is `` `${timestamp}.${rawBody}` `` (the **raw**, unparsed body).
Multiple signatures appear during a 24h key rotation; the notification is valid
if **any one** matches. Use a constant-time compare.

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

function verifyRecurlySignature(rawBody, header, secret) {
  if (!header || !secret) return false;
  const [timestamp, ...signatures] = header.split(',');
  if (!timestamp || signatures.length === 0) return false;

  const expected = crypto
    .createHmac('sha256', secret)
    .update(`${timestamp}.`)
    .update(rawBody)                 // Buffer/string of the raw request body
    .digest('hex');

  const expBuf = Buffer.from(expected);
  return signatures.some((sig) => {
    const sigBuf = Buffer.from(sig.trim());
    return sigBuf.length === expBuf.length && crypto.timingSafeEqual(sigBuf, expBuf);
  });
}
```

## Parsing the Notification

Classic Recurly JSON webhooks use the **notification type as the single
top-level key**, wrapping the related objects:

```json
{
  "new_subscription_notification": {
    "account": { "account_code": "1", "email": "verena@example.com" },
    "subscription": { "uuid": "8435b96eb70e5640a0eaf82d0e0d6d", "state": "active" }
  }
}
```

Read the notification type from the top-level key, then dispatch:

```javascript
const notification = JSON.parse(rawBody);
const type = Object.keys(notification)[0];      // e.g. "new_subscription_notification"
const data = notification[type];                 // { account, subscription | transaction, ... }
```

> **Confirm state via the API before acting.** Webhooks can arrive out of order.
> For critical flows, fetch the referenced object with the `recurly` SDK to
> confirm its current state (e.g. `client.getSubscription('uuid-' + data.subscription.uuid)`).

## Common Notification Types

| Notification | Triggered When |
|--------------|----------------|
| `new_subscription_notification` | A subscription is created |
| `updated_subscription_notification` | A subscription is upgraded, downgraded, or changed |
| `canceled_subscription_notification` | A subscription is canceled |
| `expired_subscription_notification` | A subscription expires |
| `renewed_subscription_notification` | A subscription renews for a new term |
| `successful_payment_notification` | A payment succeeds |
| `failed_payment_notification` | A payment is declined |
| `new_account_notification` | A new account is created |

## Environment Variables

```bash
RECURLY_WEBHOOK_SECRET=xxxxx        # Endpoint secret key (Webhook Endpoints page) — signs JSON
RECURLY_WEBHOOK_USER=xxxxx          # Optional: HTTP Basic Auth username configured in Recurly
RECURLY_WEBHOOK_PASSWORD=xxxxx      # Optional: HTTP Basic Auth password configured in Recurly
RECURLY_API_KEY=xxxxx               # Optional: API key to confirm object state via the SDK
```

## Local Development

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

## 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 (Recurly may deliver a notification more than once)
- [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) — Recurly retries with exponential backoff for up to 10 attempts
