$credentials = base64_encode($secretKey . ':' . $companyId);

$headers = [
    'Authorization: Basic ' . $credentials,
    'Content-Type: application/json'
];

$data = json_encode([
    "data" => "example"
]);

$curl = curl_init();
curl_setopt_array($curl, [
    CURLOPT_URL => "https://api.korepay.com.br/functions/v1/transactions",
    CURLOPT_RETURNTRANSFER => true,

### KorePay Gateway API Authentication

Source: https://korepay.readme.io/reference/index

Details on how to authenticate with the KorePay Gateway API using Basic Authentication with Secret Key and Company ID.

```APIDOC
## Authentication

### Authentication Method: Authorization Basic

To access the API, use **Authorization Basic** with the following credentials:
  * **Username**: Secret Key
  * **Password**: Company ID

### How to Obtain Credentials
  1. Access the gateway dashboard.
  2. Navigate to **Integrations → API Keys**.
  3. Copy the **Secret Key** (to be used as username).
  4. Copy the **Company ID** (to be used as password).

### Authentication Implementation
When making requests, include the credentials in the HTTP header `Authorization` using Basic Authentication:

#### Header Format:
```
Authorization: Basic {base64_encoded_credentials}
```

Where `{base64_encoded_credentials}` is the Base64 encoding of the string `{SECRET_KEY}:{COMPANY_ID}`.

#### Example in Node.js:
```typescript
const secretKey = "your_secret_key_here";
const companyId = "your_company_id_here";

const credentials = Buffer.from(`${secretKey}:${companyId}`).toString("base64");

const options = {
    method: "POST",
    url: "https://api.korepay.com.br/functions/v1/transactions",
    headers: {
        "Authorization": `Basic ${credentials}`,
        "Content-Type": "application/json"
    },
};
```

#### Example in PHP:
```php
<?php
$secretKey = "your_secret_key_here";
$companyId = "your_company_id_here";

$credentials = base64_encode($secretKey . ':' . $companyId);

$headers = [
    'Authorization: Basic ' . $credentials,
    'Content-Type: application/json'
];

$data = json_encode([
    "data" => "example"
]);

$curl = curl_init();
curl_setopt_array($curl, [
    CURLOPT_URL => "https://api.korepay.com.br/functions/v1/transactions",
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_POST => true,
    CURLOPT_POSTFIELDS => $data,
    CURLOPT_HTTPHEADER => $headers
]);

$response = curl_exec($curl);
$httpCode = curl_getinfo($curl, CURLINFO_HTTP_CODE);
curl_close($curl);

if ($httpCode === 200) {
    $result = json_decode($response, true);
    // Process response
} else {
    // Handle error
    echo "Request error: " . $httpCode;
}
?>
```

#### Example in cURL:
```bash
curl -X POST \
  https://api.korepay.com.br/functions/v1/transactions \
  -H "Authorization: Basic $(echo -n 'SECRET_KEY:COMPANY_ID' | base64)" \
  -H "Content-Type: application/json" \
  -d '{"data": "example"}'
```

### Authentication Error Handling
In case of invalid credentials, the API will return:
  * **Status Code**: `401 Unauthorized`
  * **Response**:

```text
Unauthorized
```
```
