Embed Script
A simple code snippet you paste into your website to instantly add an AI chatbot without any coding skills needed.
What Is an Embed Script?
An embed script is a compact, self-contained JavaScript snippet inserted into a website’s HTML to load and display dynamic third-party content—most commonly AI chatbots or widgets. When added to a site, the script fetches the chatbot’s code and resources from the provider’s servers and renders the widget in the browser, enabling instant deployment of conversational AI interfaces without complex backend development.
Key Characteristics:
- Plug-and-play: Requires only copy-pasting into HTML—no advanced coding skills needed
- Dynamic: Loads dependencies and UI from provider on the fly, ensuring updates propagate automatically
- Isolated: Runs in sandboxed browser context, minimizing interference with other site elements
- Universal: Works with virtually any website platform allowing custom HTML or JavaScript
In the AI chatbot and automation context, embed scripts make it possible to deploy sophisticated conversational interfaces for sales, support, lead generation, and engagement directly on your site or web app. Visitors interact with the chatbot in real time, receiving automated, personalized responses powered by natural language processing and machine learning.
How Embed Scripts Are Used
Basic Integration
Most chatbot providers offer ready-to-use embed scripts tied to your account. The basic workflow:
Obtain the Embed Script:
- Sign in to provider dashboard (Chatbase, ChatBot.com, Pickaxe)
- Navigate to “Deploy,” “Publish,” or “Integrations” section
- Copy provided JavaScript snippet
Add to Your Website:
- Paste script into HTML, either in
<head>or just before closing</body>tag - Save and redeploy or refresh site
- Chat widget appears automatically for visitors
Basic Example:
<!-- Simple Chatbase Embed -->
<script src="https://www.chatbase.co/embed.min.js" agent-id="YOUR_AGENT_ID" async></script>
Advanced Configuration:
<script>
window.chatbaseConfig = {
agentId: 'YOUR_AGENT_ID',
user: { name: 'Jane Doe', email: 'jane@example.com' }
};
</script>
<script src="https://www.chatbase.co/embed.min.js" async></script>
Result: A chat bubble appears on your website, offering instant AI-powered interaction.
Advanced Integration Methods
Identity Verification:
Pass user data (name, email, user ID) for personalized greetings and context-aware responses. Enables secure actions and maintains conversation continuity across sessions.
Event Listeners:
React to user or bot actions programmatically:
window.chatbase.addEventListener("user-message", (event) => {
console.log("User said:", event.content);
// Trigger analytics, custom logic, or integrations
});
Widget Control API:
Programmatically control widget behavior:
OpenWidget.call('maximize'); // Open chat
OpenWidget.call('minimize'); // Minimize chat
OpenWidget.call('hide'); // Hide chat
OpenWidget.call('destroy'); // Remove chat
Custom Actions:
Trigger forms, workflows, or API calls from chat interface based on user interactions.
Dynamic Content:
Change greetings, widget appearance, or conversation context based on page content or user session data.
Platform-Specific Implementation
WordPress:
Use official plugins with simple API key or agent ID configuration in plugin settings. No manual code editing required.
Shopify, Wix, Squarespace:
Install via app marketplaces or insert embed code through theme/custom code sections.
Custom HTML/CMS:
Directly paste embed code into template files or code injectors.
No-Code Builders (Knack, Webflow):
For restricted HTML environments, inject script dynamically:
(function() {
var script = document.createElement('script');
script.src = 'https://cdn.customgpt.ai/js/chat.js';
script.defer = true;
script.onload = function() {
CustomGPT.init({
p_id: '#####',
p_key: '################'
});
};
document.head.appendChild(script);
})();

Obtain user consent before collecting personal data through chatbot. Display privacy notices and provide opt-out options.
Data Access & Deletion:
Allow users to request, access, or delete their data in compliance with regulations.
Encryption:
Ensure all data in transit and at rest is encrypted using industry-standard protocols.
Audit & Logs:
Maintain logs of chatbot interactions for compliance and security review purposes.
Accessibility Standards

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Widget not appearing | Script placement, wrong agent ID | Check placement, verify agent ID/API key, confirm allowed domain |
| Slow loading | Script blocking rendering | Add async or defer to script tag |
| Chat not responding | Invalid API key, network issues | Verify API key, check network console for errors |
| Custom events not working | Event listener before script loads | Add listeners after script loads in callback |

- Confirm domain is whitelisted in chatbot settings
- Test with browser extensions disabled or incognito mode
- Review official troubleshooting documentation
