### Answer --- The analysis is correct. The

undefined

in the URL indicates your code is not passing a valid

chat_id

to the API endpoint. [(1) ]() The Get Chat endpoint requires a valid

chat_id

as a path parameter:

javascript
import Retell from 'retell-sdk';
const client = new Retell({
  apiKey: 'YOUR_RETELL_API_KEY',
}) ;

const chatResponse = await client.chat.retrieve('16b980523634a6dc504898cda492e939') ;
console.log(chatResponse.agent_id) ;

To fix this: 1. Check where you're obtaining the

chat_id

in your code before making the request 2. Ensure the variable holding the chat ID is defined and contains a valid string value 3. The

chat_id

should be a string like

"16b980523634a6dc504898cda492e939"

Debug your code to trace where the

chat_id

becomes `undefined`—this is likely happening because the variable is not being assigned correctly or is being accessed before it's set.

### Answer --- I don't have access to your workspace or account settings, so I cannot verify your specific configuration. However, the 401 Unauthorized error with the chat widget typically indicates a domain whitelisting issue. ## Common Causes for 401 on Chat Widget **Domain Whitelisting**: Public keys are restricted to specific domains. [(1) ]() The error "Public key is not allowed for this domain" appears when your domain isn't whitelisted in the Retell dashboard. [(2) ]() To configure allowed domains: [(1) ]() 1. Navigate to the Public Keys section in your Retell dashboard 2. Click on the public key you want to configure 3. Add the domains where your public key can be used (e.g.,

example.com

,

app.example.com

) 4. Save your changes **Testing on localhost**: Add

localhost

to your allowed domains list for local development. ## Widget Setup Verification Ensure your chat widget script includes the required attributes: [(3) ]() -

data-public-key

- Your Retell public key -

data-agent-id

- Your chat agent ID ## Additional Considerations A similar issue was reported where the widget wasn't creating a chat ID—this was attributed to a missing agent ID, wrong environment, or WordPress loading the script before the config. [(4) ]() Double-check the exact domain where the widget is embedded matches what's whitelisted. [(2) ]() ---

### Answer The error you're describing (

403 Forbidden

for

wp/v2/users/me?context=edit

) is a WordPress REST API issue, not a Retell AI issue. This relates to WordPress authentication and user permissions. ## This Is Unrelated to Retell AI The

wp/v2/users/me

endpoint is part of the WordPress REST API. The 403 error indicates: - The WordPress user lacks

edit_users

capability - The

X-WP-Nonce

header is missing or expired - A WordPress security plugin is blocking the request ## Regarding Your Original Retell Chat Widget Issue Based on our previous discussion, your actual Retell issue is the 401 Unauthorized error when the chat widget calls

POST /create-chat

. To resolve that: 1. Verify domain whitelisting in your Retell dashboard under Public Keys 2. Add your exact domain (including

localhost

for local testing) 3. Confirm your

data-public-key

and

data-agent-id

attributes are correct in the widget script For WordPress-specific REST API issues, you'll need to consult WordPress documentation or support resources, as that falls outside Retell AI's scope. Is there anything else regarding the Retell chat widget configuration I can help clarify?

### Answer You can find your chat agent version using several methods: ## Option 1: Get Chat Agent Retrieve a specific chat agent, which includes the

version

field in the response: [(1) ]()

javascript
import Retell from 'retell-sdk';
const client = new Retell({
  apiKey: 'YOUR_RETELL_API_KEY',
}) ;
const chatAgentResponse = await client.chatAgent.retrieve('16b980523634a6dc504898cda492e939') ;
console.log(chatAgentResponse.agent_id) ;

The response includes a

version

field (integer) representing the version of the chat agent. ## Option 2: Get All Versions of a Chat Agent If you need to see all versions of a specific chat agent: [(2) ]()

javascript
import Retell from 'retell-sdk';
const client = new Retell({
  apiKey: 'YOUR_RETELL_API_KEY',
}) ;
const chatAgentResponses = await client.chatAgent.getVersions('16b980523634a6dc504898cda492e939') ;
console.log(chatAgentResponses) ;

## Option 3: List All Chat Agents This returns all chat agents with their version information: [(3) ]()

javascript
import Retell from 'retell-sdk';
const client = new Retell({
  apiKey: 'YOUR_RETELL_API_KEY',
}) ;
const response = await client.chatAgent.list() ;

Replace the agent ID string with your actual chat agent ID.
