Does it use the same credits as WhatsApp?

Yes. The chat plugin uses the same functions and credits as your WhatsApp assistant. Each response consumes credits according to the length of the message and the processed context.

Can I use a different prompt for the web?

Yes. You have two options: write a specific prompt for the web in the plugin settings, or automatically sync your WhatsApp prompt (the AI adapts it by removing references to WhatsApp).

What languages does the chat support?

Spanish, English, German, French, Portuguese, Italian, and Hungarian. You can set automatic detection, fixed language, or let the visitor choose.

Does it work with integrations like Shopify?

Yes. The plugin’s AI has access to the same functions: product search, customer information, custom functions, and CRM endpoints that you have configured.

How do I protect the chat from being used on other domains?

In the “Authorized Domains“ section, you must add the domains where you want the chat to work. Use is only allowed from authorized domains.

Is there a message limit per user?

Yes. You can configure rate limiting to prevent abuse. By default, it is 30 messages every 60 minutes per session.

Web Chat Plugin with AI - WAzion Documentation

What is the Chat Plugin?

The chat plugin allows you to add an AI assistant to any website. Visitors can chat directly with the AI without needing WhatsApp, and you can assist them using the same integrations and features you already have configured.

• Automatic responses with AI trained on your business
• Access to product, customer, and customized function search
• Multi-language support with automatic translation
• 10 customizable design themes
• Floating mode (button in corner) or embedded (inside a div)

How to activate the plugin

Open the WAzion Dashboard
In the side menu, click on “Plugins“ → “Chat
Activate the “Plugin active“ switch
Add your domain in “Authorized Domains“ (e.g., mitienda.com)
Copy the integration code and paste it into your website

Integration code

Copy this code and paste it before closing the tag of your website:

<!-- WAzion Chat Web -->
<script>
(function(w,d,s,t){if(w.WazionPlugin)return;w.WazionPlugin={token:t};
var js=d.createElement(s);js.async=true;
js.src='https://www.wazion.com/plugins/chat/embed.js';
js.dataset.token=t;d.body.appendChild(js);
})(window,document,'script','TU_TOKEN_AQUI');
</script>

The token is generated automatically when activating the plugin. You will find it in the chat settings section.

Embedded mode (optional)

If you prefer to insert the chat inside a specific container instead of as a floating button, wrap the code in a div:

<div id="mi-chat" style="height: 500px;">
  <script>
  (function(w,d,s,t){if(w.WazionPlugin)return;w.WazionPlugin={token:t};
  var js=d.createElement(s);js.async=true;
  js.src='https://www.wazion.com/plugins/chat/embed.js';
  js.dataset.token=t;d.body.appendChild(js);
  })(window,document,'script','TU_TOKEN_AQUI');
  </script>
</div>

The chat will be rendered inside the container div instead of as a floating button.

  script.src = 'https://www.wazion.com/plugins/chat/embed.js';
  script.dataset.token = 'TU_TOKEN_AQUI';
  script.async = true;
  document.body.appendChild(script);

  return () => document.body.removeChild(script);
}, []);

Problem solving

The chat does not appear

→ Check that the plugin is activated in the Dashboard
→ Check that your domain is on the list of authorized domains
→ Open the browser console (F12) and look for errors
→ Test in an incognito window to rule out cache issues

Error “Unauthorized domain

→ Add your exact domain to the authorized list (without http:// or /)
→ If you use www, add both “midominio.com“ and “www.midominio.com
→ For local development, add “localhost“ or use “*“ temporarily

The chat appears but does not respond

→ Check that you have credits available in your account
→ Check that the token is correct
→ Check if you have reached the rate limiting threshold
