Celsian AI Chat Service
Once connected, the plugin communicates with Celsian AI servers:
<ul>
<li>Widget assets — JavaScript and CSS files are loaded from <code>chatbots.celsian.ai/widget/</code> to render the chat widget on your site. These files are required for the chatbot to function and cannot be bundled locally as they are part of the hosted service.</li>
<li>Chat API — When a visitor sends a message, it is sent to <code>converse.chatbots.celsian.ai/converse</code> along with the chatbot ID, the message text, and a randomly generated anonymous visitor ID. The AI response is returned and displayed in the widget.</li>
<li>Auto Setup (admin only) — If you use Auto Setup, the plugin opens <code>chatbots.celsian.ai</code> in a new tab with your site URL and site name to streamline the connection process.</li>
</ul>

<h3>⚙️ Frequently Asked Questions</h3>
<h4>Do I need an API key or account to use this plugin?</h4>
You need to register at WebChatAgent.com to create a chatbot and get a Chatbot ID. You then enter this ID in the plugin settings to connect your WordPress site to your chatbot. API keys and model settings are managed in your WebChatAgent account.
<h4>Is this plugin completely free?</h4>
You can start with a free plan on WebChatAgent.com. There are paid plans available if you need higher limits, more pages, more traffic or advanced features like higher message quotas, team features and additional integrations.
<h4>Can I customize the appearance of the chat widget?</h4>
Yes. You customize the color scheme, avatar, fonts, welcome message, widget position, behavior and persona directly in the WebChatAgent dashboard. The WordPress plugin shows a live preview and uses your current configuration.
<h4>Is WebChatAgent GDPR (DSGVO) compliant?</h4>
Yes. WebChatAgent operates in accordance with the GDPR. IP addresses are stored in anonymized form for abuse prevention, chat conversations are kept only for a limited time, and old conversations and personal data are cleaned up automatically after a configurable retention period. See the Privacy Policy section below for details.
<h4>Can I embed the chat inside a page instead of the floating button?</h4>
Yes. Use the <code>[webchatagent_inline]</code> shortcode (Classic Editor, page builders, text widgets) or the WebChatAgent Inline Chat Gutenberg block to place the chat directly inside your content — for example on a product page, contact page or news article. Both use the Chatbot ID from the plugin settings; you can override it per embed with <code>chatbot-id="..."</code> (or via the block sidebar). The inline embed works independently of the Enable Chatbot toggle, which only controls the floating widget, and the widget script loads only on pages that use it.
<h4>Is the chat widget mobile-friendly?</h4>
Yes, the chat widget is fully responsive and works well on all devices, including mobile phones and tablets.
<h4>Does WebChatAgent support live chat and human takeover?</h4>
Yes. WebChatAgent offers a hybrid model: AI answers most questions automatically, and your team can take over any chat at any time via the Agent Inbox. You can reply as a human and then hand control back to the bot if you like.
<h4>Does the plugin support WhatsApp Business?</h4>
Yes. You can connect your WhatsApp Business number in the WebChatAgent dashboard. Your AI chatbot can then reply to WhatsApp messages, and you can manage those conversations alongside website chats.
<h4>How does the AI chatbot understand my website content?</h4>
WebChatAgent uses RAG (Retrieval-Augmented Generation) to index and understand your website content and documents. When visitors ask questions, the AI combines this indexed content with a large language model (e.g. ChatGPT or Gemini) to provide accurate, context-aware answers.
<h4>Which AI models are supported?</h4>
The chatbot supports multiple large language models including OpenAI ChatGPT, Google Gemini (incl. Gemini 3.5 Flash), xAI Grok, and Mistral AI. You can choose which model to use in your WebChatAgent settings. Speed and quality indicators help you pick the right model. Additionally, you can connect custom MCP (Model Context Protocol) servers for self-hosted or specialized AI models.
<h4>Does the chatbot support multiple languages?</h4>
Yes, the chatbot automatically detects and responds in the user’s language, making it ideal for multilingual websites. Human replies in the inbox can also be auto-translated.
<h4>Is the chat widget accessible for people with disabilities?</h4>
Yes, the chat widget is designed to meet WCAG 2.2 AA accessibility standards, ensuring it’s usable for all visitors, including those using assistive technologies.
<h4>Can the chatbot perform actions beyond just answering questions?</h4>
Yes. With Tool Integrations, your chatbot can connect to external services and systems to perform actions such as submitting forms, booking appointments, updating records or querying databases. You configure these tools in your WebChatAgent dashboard.
<h4>What is the API Connector and how does it work?</h4>
The API Connector lets your chatbot answer questions that require live data from your WooCommerce shop or other business systems. Instead of just answering general questions, your chatbot can look up real information for each customer.
WooCommerce examples:
<ul>
<li>“Where is my order #12345?” – The chatbot checks your WooCommerce shop and tells the customer the current order status</li>
<li>“Is the blue T-shirt in size M available?” – Looks up product stock and availability in WooCommerce</li>
<li>“Show me my recent orders” – Displays the customer’s order history from your shop</li>
</ul>
Other systems:
<ul>
<li>Support tickets – Show ticket status from helpdesk systems</li>
<li>Account info – Look up balances, memberships or custom data from any system</li>
</ul>
How to set it up:
<ol>
<li>Select the WooCommerce template (or another template for your system)</li>
<li>The chatbot asks customers to verify their identity (e.g. their order email)</li>
<li>Once verified, the chatbot can look up their orders, products and personal data</li>
</ol>
No programming knowledge required — the WooCommerce connector works out of the box.
<h4>What analytics and management tools are included?</h4>
From your WebChatAgent account, you can access:
<ol>
<li>Lead Management – Collect, categorize and follow up with leads generated through your chatbot </li>
<li>Feedback Management – Review and analyze user feedback to improve your chatbot and service </li>
<li>Questions Management – View all questions asked to your chatbot, identify common topics and improve your knowledge base </li>
<li>Analytics Dashboard – Track conversations, leads, bookings, human handovers and unanswered questions</li>
</ol>
<h4>How does the spam protection work?</h4>
Built-in spam and abuse protection monitor usage patterns and prevent abusive or excessive requests. This helps protect your account from unexpected usage spikes and keeps your costs predictable on higher tiers.
