### Answer Based on the official documentation, both

data-title

and

data-logo-url

are supported attributes in the v2 chat widget [(1) ]() . The widget script should include these attributes like this :

html
<script
 id="retell-widget"
 src="<https://dashboard.retellai.com/retell-widget-v2.js%22>
 type="module"
 data-public-key="YOUR_RETELL_PUBLIC_KEY"
 data-agent-id="YOUR_CHAT_AGENT_ID"
 data-title="YOUR_CUSTOM_TITLE"
 data-logo-url="YOUR_LOGO_URL"
></script>

According to the documentation,

data-title

sets a custom chat window title (default is "Chat") , and

data-logo-url

specifies the URL of your logo image . There has been a similar reported issue where the

data-title

attribute wasn't rendering properly [(2) ]() . In that case, the Retell support team investigated and requested additional details like the agent ID and website code to diagnose the problem . If these attributes aren't working for you, I recommend: 1. Verifying your script tag matches the format above with `src=" [(1) ]() 2. Checking if your framework (React, Next.js, etc.) might be sanitizing or overriding these attributes during hydration [(3) ]() 3. Creating a bug report ticket with your agent ID and website details so the support team can investigate [(2) ]()

### Answer Thank you for the clarification. This appears to be a regression issue with the v2 widget where

data-title

and

data-logo-url

attributes that worked in v1 are not functioning properly in v2 [(1) ]() . There have been similar reports from other users experiencing the same problem with these attributes in the v2 widget [(1) ]() [(2) ]() . In the documented case, the Retell support team acknowledged the issue and escalated it for investigation after the user confirmed the attributes were correctly configured in their script tag [(1) ]() . Since you've confirmed this worked in v1 but not v2, I recommend: 1. Verify your v2 script configuration matches the documented format [(3) ]() :

html
<script
  id="retell-widget"
  src="<https://dashboard.retellai.com/retell-widget-v2.js%22>
  type="module"
  data-public-key="YOUR_RETELL_PUBLIC_KEY"
  data-agent-id="YOUR_CHAT_AGENT_ID"
  data-title="YOUR_CUSTOM_TITLE"
  data-logo-url="YOUR_LOGO_URL"
></script>

2. Contact Retell support with your agent ID and website details so they can investigate this v2-specific issue [(1) ]() . Based on the documented cases, the support team has been responsive to these widget rendering problems and works to resolve them. This appears to be a known issue with the v2 widget that requires support team investigation rather than a configuration problem on your end.
