# Notificaciones Webhooks

**Webhook** es una notificación que le envía **pagoUno** relacionada a sus transacciones.

El sistema enviará una notificación a la `URL` indicada por el cliente.

Para recibir las notificaciones en esa URL debe comunicarse con nuestro [soporte ](/soporte-pagouno.md)e informarla allí para que procedamos a su configuración.

Una vez que nuestro soporte configura el endpoint de notificación, con cada evento en el gateway se enviará una petición `HTTP POST`con el siguiente JSON en el body:

### Json Ejemplo

```javascript
{
    "id_news": 352221,
    "type": "Transaction",
    "id_object": 1069852,
    "id_news_type": 200,
    "action": "Response received and processed (success).",
    "date_created": "2019-09-25T11:02:45.154-03:00",
    "version": 1,
    "data": {
        "id": "897D7EFB-EBB5-4960-B92F-0AE9C034457A",
        "transaction_amount": 1000,
        "bin": "545454",
        "last_4_digit": "1234",
        "checkout_id": "804e8659-0f49-4be5-9d0c-611ed614b801", 
        "external_reference": "Venta On-Line"
    }
}
```

Esto indica que la transacción con id 

```javascript
"897D7EFB-EBB5-4960-B92F-0AE9C034457A"
```

o con id de botón de pago 

```javascript
"804e8659-0f49-4be5-9d0c-611ed614b801"
```

fue recibida y procesada exitosamente con fecha

```javascript
"2019-09-25T11:02:45.154-03:00"
```

### **PagoUno notifica los siguientes eventos**

| **id\_news\_type** | **type**      | **action**                                   |
| ------------------ | ------------- | -------------------------------------------- |
| `200`              | `Transaction` | `Response received and processed (success)`. |
| `201`              | `Transaction` | `Response received and processed (fail).`    |
| `320`              | `Transaction` | `Rollback executed (with annulment).`        |
| `322`              | `Transaction` | `Rollback executed (with devolution).`       |
| `400`              | `Transaction` | `Transaction annulment executed.`            |
| `410`              | `Transaction` | `Transaction devolution executed.`           |

### **¿Qué debe hacer al recibir una notificación?**

Cuando recibe una notificación en su plataforma, **pagoUno** espera una respuesta para saber que fue recibida. 

Debe devolver un `HTTP STATUS 200` (OK) ó `HTTP STATUS 201` (CREATED).\ <br>
