What are the potential differences in parameter handling between GET and POST methods in PHP when interacting with the Paypal API?

When interacting with the Paypal API, one potential difference in parameter handling between GET and POST methods in PHP is that GET requests append parameters to the URL, while POST requests send parameters in the request body. To ensure proper parameter handling with the Paypal API, it is important to use the correct method (GET or POST) based on the API documentation. 

// Example of making a GET request to the Paypal API
$api_url = 'https://api.paypal.com';
$api_params = [
    'param1' => 'value1',
    'param2' => 'value2'
];
$api_url .= '?' . http_build_query($api_params);
$response = file_get_contents($api_url);

// Example of making a POST request to the Paypal API
$api_url = 'https://api.paypal.com';
$api_params = [
    'param1' => 'value1',
    'param2' => 'value2'
];
$options = [
    'http' => [
        'method' => 'POST',
        'header' => 'Content-type: application/x-www-form-urlencoded',
        'content' => http_build_query($api_params)
    ]
];
$context = stream_context_create($options);
$response = file_get_contents($api_url, false, $context);
