Cross-Site Embed

The plugin includes an optional embed loader script (embed-loader.js) for embedding the chatbot on external websites via an iframe. This script does not load any external CDN resources or third-party scripts — it creates an iframe pointing back to your own WordPress site. All data processing occurs on your server.

Data Transmitted to External Services

User messages: Chat messages entered by visitors (sent to the configured AI provider only)
Site content (if Site Learning is enabled): Excerpts from your published posts/pages (sent to the configured AI provider)
Knowledge base (if configured): Custom Q&A entries you create (sent to the configured AI provider)
IP address (reCAPTCHA only): Sent to Google for spam verification

Data Storage

Conversation history: Stored locally in your WordPress database (can be disabled)
Visitor IP: Stored as SHA-256 hash (not plain text) for rate limiting
Retention: Configurable auto-deletion period (default 90 days)

User Controls

You can disable these features in the plugin settings: * Conversation history saving * Site content crawling/learning * Google reCAPTCHA verification * Web search

Privacy

Data Collected

When conversation history is enabled, the plugin stores: * Chat messages (user and AI responses) * Session identifiers * Page URLs where chats occurred * Hashed IP addresses (SHA-256, not reversible) * Timestamps

Conversation data is automatically deleted after the configured retention period (default: 90 days). Administrators can manually delete conversations at any time.

User Rights

The plugin provides hooks and filters for customization:

Available Filters

raplsaich_system_prompt — Modify the system prompt sent to AI
raplsaich_context — Modify the context from site learning
raplsaich_ai_response — Filter the AI response before display
raplsaich_chatbot_enabled — Control chatbot visibility programmatically
raplsaich_allowed_origins — Add allowed origin hosts for same-origin check
raplsaich_chat_response_data — Filter chat response data before returning to client
raplsaich_gpt5_token_multiplier — GPT-5 reasoning token multiplier (default: 4, range: 1-8)

Example: Custom System Prompt

add_filter( 'raplsaich_system_prompt', function( $prompt, $settings ) {
    return $prompt . "\n\nAlways end responses with a friendly emoji.";
}, 10, 2 );

Example: Conditionally Hide Chatbot

add_filter( 'raplsaich_chatbot_enabled', function( $enabled ) {
    // Hide on checkout page
    if ( is_page( 'checkout' ) ) {
        return false;
    }
    return $enabled;
} );

REST API Endpoints

The plugin registers REST API endpoints under the rapls-ai-chatbot/v1 namespace:

Session authentication: Pass the session ID via the X-RAPLSAICH-Session HTTP header (recommended). When the header is present, any session_id in the request body is ignored (prevents APM/WAF body-logging leakage). Query string parameters (?session_id=...) are not accepted for GET requests to prevent session leakage in server access logs.

Free:

GET /rapls-ai-chatbot/v1/session — Get or create a chat session
POST /rapls-ai-chatbot/v1/chat — Send a message and receive AI response
GET /rapls-ai-chatbot/v1/history/{session_id} — Get conversation history
POST /rapls-ai-chatbot/v1/feedback — Rate a response (thumbs up/down)
POST /rapls-ai-chatbot/v1/regenerate — Regenerate AI response
GET /rapls-ai-chatbot/v1/message-limit — Check message limits
POST /rapls-ai-chatbot/v1/lead — Submit lead form
GET /rapls-ai-chatbot/v1/lead-config — Lead form configuration

The Pro add-on registers additional endpoints for analytics, scenarios, LINE, and more. See the Pro documentation for details.

Settings Architecture

Extension settings are stored under the extensions key in raplsaich_settings. For backward compatibility, the legacy pro_features key is read as a fallback but all new settings are written to extensions.

Database Tables

The plugin creates the following database tables:

{prefix}_aichat_conversations — Chat sessions
{prefix}_aichat_messages — Individual messages with token tracking
{prefix}_aichat_index — Site learning content index
{prefix}_aichat_knowledge — Custom knowledge base entries
{prefix}_aichat_leads — Lead capture data

Uninstallation

When uninstalled with “Delete data on uninstall” enabled, the plugin removes all database tables, options, and transients. Without this setting, data is preserved for re-installation.

Development

Release ZIPs are CI-verified for packaging correctness. Report any issues via the support forum.
