The SureFeedback Client Site plugin is a sophisticated WordPress plugin designed to create a secure bridge between client websites and a centralized SureFeedback parent dashboard. This plugin enables real-time feedback collection through a sticky note-style interface, allowing clients to provide targeted feedback on specific areas of web designs and projects.
- Centralized Feedback Management: Single dashboard to manage feedback from multiple client sites
- Streamlined Client Experience: No registration required for clients already logged into their sites
- White Label Support: Full customization for agencies to brand the plugin as their own
- Multi-site Architecture: Scalable solution for agencies managing multiple client projects
- WordPress plugin architecture with secure REST API integration
- Cross-origin resource sharing (CORS) implementation for secure communication
- Role-based access control with granular permissions
- Token-based authentication system with HMAC signatures
- Compatibility with major page builders (Elementor, Divi, Beaver Builder, etc.)

The plugin implements a sophisticated multi-layer security system:
-
Access Token Validation
public function verify_access($request) { $token = $request->get_header('X-SureFeedback-Token'); $valid_token = get_option('surefeedback_access_token', ''); if (!hash_equals($valid_token, $token)) { return new WP_Error('rest_forbidden', 'Invalid access token'); } }
-
HMAC Signature Generation
$args['ph_signature'] = hash_hmac( 'sha256', sanitize_email($user->user_email), get_option('surefeedback_signature', false) );
-
Role-Based Access Control
- Granular role selection for comment visibility
- Guest user support with explicit permission
- Admin dashboard commenting toggle

The plugin implements selective CORS policies that only apply to SureFeedback endpoints:

$route = $request->get_route();
if (strpos($route, '/surefeedback/') !== 0) return $served;

header('Access-Control-Allow-Credentials: true');
header('Access-Control-Allow-Methods: GET, POST, OPTIONS, PUT, DELETE');
header('Access-Control-Allow-Headers: Content-Type, X-SureFeedback-Token, Authorization, X-WP-Nonce');
}, 10, 4);
