What best practices should be followed when integrating PHP code with WordPress plugins like ContactForm7 for form functionality?

When integrating PHP code with WordPress plugins like ContactForm7 for form functionality, it is important to use WordPress hooks and filters to ensure compatibility and avoid conflicts with other plugins or themes. Additionally, it is recommended to create a custom plugin or theme file to contain your PHP code, rather than directly modifying the plugin files. This helps to maintain the integrity of the plugin and makes it easier to update in the future. 

// Example of integrating PHP code with ContactForm7 plugin
// Add custom functionality to form submission

add_action('wpcf7_before_send_mail', 'custom_form_submission');

function custom_form_submission($contact_form) {
    // Get form data
    $submission = WPCF7_Submission::get_instance();
    if ($submission) {
        $posted_data = $submission->get_posted_data();
        // Custom code to process form data
        // Example: Send form data to an external API
        $response = wp_remote_post('https://api.example.com/submit-form', array(
            'body' => $posted_data,
        ));
        // Log API response
        if (!is_wp_error($response)) {
            error_log('Form submitted successfully: ' . $response['body']);
        } else {
            error_log('Error submitting form: ' . $response->get_error_message());
        }
    }
}
