## Webhook'lar

Hesabinizda olaylar gerceklestiginde gercek zamanli HTTP POST bildirimleri almak icin bir webhook URL'si yapilandirin.

### Desteklenen olaylar

| Olay                   | Aciklama                       |
| ---------------------- | ------------------------------ |
| `order.filled`         | Enerji siparisi tamamlandi     |
| `order.failed`         | Enerji siparisi basarisiz oldu |
| `deposit.confirmed`    | Yatirma bakiyeye eklendi       |
| `invoice.paid`         | Fatura odemesi alindi          |
| `invoice.delegated`    | Fatura enerjisi devredildi     |
| `smart_mode.transfer`  | Akilli Mod transferi islendi   |
| `withdrawal.completed` | Cekim gonderildi               |

### Webhook yuku

```json theme={null}
{
  "event": "order.filled",
  "data": {
    "order_id": 1234,
    "address": "TAddress...",
    "energy_amount": 65000,
    "price_trx": "2.75"
  },
  "timestamp": "2026-03-04T12:00:00Z"
}
```

### Gereksinimler

* URL **HTTPS** kullanmalidir
* 10 saniye icinde `2xx` durum koduyla yanit vermeli
* Basarisiz teslimler, ustel geri cekilme ile 3 kez yeniden denenir

### Webhook imzalarini dogrulama

Her webhook istegi, HMAC-SHA256 imzasi iceren bir `X-Webhook-Signature` basligi icerir. Istegin TronRental'den geldigini dogrulamak icin bunu kullanin.

Imza, webhook siriniz kullanilarak ham istek govdesi uzerinden hesaplanir ([webhook'unuzu yapilandirdiginizda](/api-reference/webhooks/configure) dondurulur).

<CodeGroup>
  ```python Python theme={null}
  import hmac
  import hashlib

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

  # In your webhook handler:
  # payload = request.body  (raw bytes)
  # signature = request.headers["X-Webhook-Signature"]
  # secret = "whsec_abc123..."  (from configure response)
  # if not verify_webhook(payload, signature, secret):
  #     return Response(status_code=401)
  ```

  ```javascript JavaScript theme={null}
  const crypto = require("crypto");

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

  // In your webhook handler:
  // const payload = req.rawBody;  // raw request body string
  // const signature = req.headers["x-webhook-signature"];
  // const secret = "whsec_abc123...";
  // if (!verifyWebhook(payload, signature, secret)) {
  //   return res.status(401).send("Invalid signature");
  // }
  ```
</CodeGroup>

<Warning>
  Webhook verilerini islemeden once imzayi her zaman dogrulayin. Zamanlama saldirilarina karsi sabit zamanli karsilastirma (`hmac.compare_digest` / `crypto.timingSafeEqual`) kullanin.
</Warning>

<Warning>
  Webhook URL'leri `localhost`, `127.0.0.1` veya diger ozel adreslere isaret edemez.
