<p>The plugin provides hooks and filters for customization:</p>
<h4>Available Filters</h4>
<ul>
<li><code>raplsaich_system_prompt</code> — Modify the system prompt sent to AI</li>
<li><code>raplsaich_context</code> — Modify the context from site learning</li>
<li><code>raplsaich_ai_response</code> — Filter the AI response before display</li>
<li><code>raplsaich_chatbot_enabled</code> — Control chatbot visibility programmatically</li>
<li><code>raplsaich_allowed_origins</code> — Add allowed origin hosts for same-origin check</li>
<li><code>raplsaich_chat_response_data</code> — Filter chat response data before returning to client</li>
<li><code>raplsaich_gpt5_token_multiplier</code> — GPT-5 reasoning token multiplier (default: 4, range: 1-8)</li>
</ul>
<h4>Example: Custom System Prompt</h4>
<pre><code>add_filter( 'raplsaich_system_prompt', function( $prompt, $settings ) {
    return $prompt . "\n\nAlways end responses with a friendly emoji.";
}, 10, 2 );
</code></pre>
<h4>Example: Conditionally Hide Chatbot</h4>
<pre><code>add_filter( 'raplsaich_chatbot_enabled', function( $enabled ) {
    // Hide on checkout page
    if ( is_page( 'checkout' ) ) {
        return false;
    }
    return $enabled;
} );
</code></pre>
<h4>REST API Endpoints</h4>
<p>The plugin registers REST API endpoints under the <code>rapls-ai-chatbot/v1</code> namespace:</p>
<p><strong>Session authentication:</strong> Pass the session ID via the <code>X-RAPLSAICH-Session</code> 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 (<code>?session_id=...</code>) are <strong>not</strong> accepted for GET requests to prevent session leakage in server access logs.</p>
<p><strong>Free:</strong></p>
<ul>
<li><code>GET /rapls-ai-chatbot/v1/session</code> — Get or create a chat session</li>
<li><code>POST /rapls-ai-chatbot/v1/chat</code> — Send a message and receive AI response</li>
<li><code>GET /rapls-ai-chatbot/v1/history/{session_id}</code> — Get conversation history</li>
<li><code>POST /rapls-ai-chatbot/v1/feedback</code> — Rate a response (thumbs up/down)</li>
<li><code>POST /rapls-ai-chatbot/v1/regenerate</code> — Regenerate AI response</li>
<li><code>GET /rapls-ai-chatbot/v1/message-limit</code> — Check message limits</li>
<li><code>POST /rapls-ai-chatbot/v1/lead</code> — Submit lead form</li>
<li><code>GET /rapls-ai-chatbot/v1/lead-config</code> — Lead form configuration</li>
</ul>
<p>The Pro add-on registers additional endpoints for analytics, scenarios, LINE, and more. See the Pro documentation for details.</p>
<h4>Settings Architecture</h4>
<p>Extension settings are stored under the <code>extensions</code> key in <code>raplsaich_settings</code>. For backward compatibility, the legacy <code>pro_features</code> key is read as a fallback but all new settings are written to <code>extensions</code>.</p>
<h4>Database Tables</h4>
<p>The plugin creates the following database tables:</p>
<ul>
<li><code>{prefix}_aichat_conversations</code> — Chat sessions</li>
<li><code>{prefix}_aichat_messages</code> — Individual messages with token tracking</li>
<li><code>{prefix}_aichat_index</code> — Site learning content index</li>
<li><code>{prefix}_aichat_knowledge</code> — Custom knowledge base entries</li>
<li><code>{prefix}_aichat_leads</code> — Lead capture data</li>
</ul>
<h4>Uninstallation</h4>
<p>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.</p>
