How can one effectively troubleshoot PHP scripts that interact with external APIs like the Telegram Bot API?

To effectively troubleshoot PHP scripts that interact with external APIs like the Telegram Bot API, make sure to check for errors in the API response, handle exceptions properly, and log any relevant information for debugging purposes. Additionally, use tools like Postman or cURL to test the API endpoints directly and verify the expected behavior. 

// Example code snippet for handling errors when interacting with the Telegram Bot API
$response = file_get_contents("https://api.telegram.org/bot<YOUR_BOT_TOKEN>/sendMessage?chat_id=<CHAT_ID>&text=Hello");

if ($response === false) {
    // Handle connection error
    echo "Error connecting to the API";
} else {
    $data = json_decode($response, true);
    
    if ($data['ok']) {
        // API call was successful
        echo "Message sent successfully";
    } else {
        // Handle API error
        echo "Error: " . $data['description'];
    }
}
