### Answer Based on the available documentation, there is no "retell-widget-v2" version mentioned. The current Retell website widget uses the script source ` [(1) ]() . The documented implementation for the Chat Widget requires adding this script tag within the

<head>

tag :

html
<script
 id="retell-widget"
 src="<https://dashboard.retellai.com/retell-widget.js%22>
 type="module"
 data-public-key="YOUR_RETELL_PUBLIC_KEY"
 data-agent-id="YOUR_CHAT_AGENT_ID"
 data-agent-version="YOUR_AGENT_VERSION"
 data-title="YOUR_CUSTOM_TITLE"
 data-logo-url="YOUR_LOGO_URL"
 data-color="YOUR_CUSTOM_COLOR"
 data-bot-name="YOUR_BOT_NAME"
 data-popup-message="YOUR_POPUP_MESSAGE"
 data-show-ai-popup="true"
 data-show-ai-popup-time="5"
 data-auto-open="false"
 data-dynamic='{"key": "value"}'
 data-recaptcha-key="YOUR_GOOGLE_RECAPTCHA_SITE_KEY"
></script>

If you're trying to use a "retell-widget-v2" script URL that you found elsewhere, it may not be the official implementation. Stick with the documented

retell-widget.js

script . Check out these potentially useful sources: [Retell Website Widget]() , [Chat Widget, Custom Function Enhancement and more!]()

### Answer I apologize for the confusion in my previous response. You're correct—I need to check the documentation more carefully. Based on the sources I have access to, the Chat Widget documentation shows the script source as ` [(1) ]() . However, you're mentioning that the documentation you're viewing references

retell-widget-v2.js

. This suggests there may be updated documentation that I don't currently have access to in my sources. If the documentation you're viewing specifically mentions

retell-widget-v2.js

, then that would be the correct script to use according to the official docs. For troubleshooting the widget not rendering: 1. Ensure you've replaced all placeholder values (YOUR_RETELL_PUBLIC_KEY, YOUR_CHAT_AGENT_ID, etc.) with your actual credentials 2. Verify the script tag is placed within the

<head>

tag 3. Check your browser console for any JavaScript errors 4. Confirm you're using a chat agent ID (not a voice agent ID) for the chat widget If you continue experiencing issues with

retell-widget-v2.js

, I'd recommend checking the [Retell Website Widget documentation]() directly to ensure you have the most current implementation details.
