What are some potential pitfalls to be aware of when using external APIs in PHP projects?

One potential pitfall when using external APIs in PHP projects is not properly handling errors or exceptions that may occur during API requests. It is important to have robust error handling in place to gracefully handle any issues that may arise, such as network errors, invalid responses, or rate limiting. 

try {
    // Make API request
    $response = file_get_contents('https://api.example.com/data');
    
    // Process API response
    $data = json_decode($response, true);
    
    // Handle API response data
    // ...
    
} catch (Exception $e) {
    // Log the error
    error_log('Error fetching data from API: ' . $e->getMessage());
    
    // Display a user-friendly error message
    echo 'An error occurred while fetching data from the API. Please try again later.';
}
