How can PHP developers effectively troubleshoot issues when integrating external APIs like blockchain.info?

When integrating external APIs like blockchain.info in PHP, developers can effectively troubleshoot issues by checking the API documentation for error codes and messages, ensuring the correct API endpoint and parameters are being used, and utilizing error handling techniques like try-catch blocks to capture and log any errors that occur during the API request. 

try {
    $url = 'https://blockchain.info/q/latesthash';
    $response = file_get_contents($url);
    
    if ($response === false) {
        throw new Exception('Failed to retrieve data from the API');
    }
    
    $data = json_decode($response, true);
    
    if (json_last_error() !== JSON_ERROR_NONE) {
        throw new Exception('Error decoding JSON response');
    }
    
    // Process the API response data here
} catch (Exception $e) {
    error_log('Error: ' . $e->getMessage());
}
