What are common pitfalls when using cUrl in PHP for RESTful API calls?

One common pitfall when using cUrl in PHP for RESTful API calls is not setting the proper headers for the request, such as the Content-Type. This can lead to errors or unexpected behavior from the API. To solve this, make sure to set the necessary headers in the cUrl request. 

$url = 'https://api.example.com/endpoint';
$data = array('key1' => 'value1', 'key2' => 'value2');

$headers = array(
    'Content-Type: application/json',
    'Authorization: Bearer YOUR_API_TOKEN'
);

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

$response = curl_exec($ch);

if($response === false){
    echo 'cURL error: ' . curl_error($ch);
}

curl_close($ch);

// Process $response as needed
