# PHP Code Example

#### Signing a Request (Example in PHP)

1️⃣ Take the request body:

```json
{
    "amount": {
        "value": "12.50",
        "currency": "EUR"
    },
    "counterparty_alias": {
        "type": "EMAIL",
        "value": "bravo@bunq.com"
    },
    "description": "Payment for drinks."
}
```

2️⃣ Sign it using your private key:

```php
openssl_sign($dataToSign, $signature, $privateKey, OPENSSL_ALGO_SHA256);
$encodedSignature = base64_encode($signature);
```

3️⃣ Add the signature to the request headers:

```http
X-Bunq-Client-Signature: [your base64-encoded signature]
```

4️⃣ Send it! 🎉
