### Answer --- Chat agents support webhooks—you need to configure the

webhook_url

on your chat agent. [(1) ]() [(2) ]() To set up webhooks for your chat agent: You can set the

webhook_url

parameter when creating or updating your chat agent. The webhook will listen to chat events for that agent. Example from the API response showing the webhook configuration:

json
{
  "agent_id": "oBeDLoLOeuAbiuaMFXRtDOLriTJ5tSxD",
  "webhook_url": "<https://webhook-url-here%22,>
  "webhook_timeout_ms": 10000
}

[(1) ]() Key parameters: -

webhook_url

— The webhook URL for the agent to listen to chat events. If set, it binds webhook events for this agent to the specified URL. Set to

null

to remove the webhook URL. [(1) ]() [(2) ]() -

webhook_timeout_ms

— The timeout for the webhook in milliseconds. Default is 10000 (10 seconds) . To configure via API (JavaScript SDK) :

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

[(1) ]() You can verify your chat agent's current webhook configuration by retrieving the agent details and checking the

webhook_url

field. If chats appear in your history but webhooks aren't firing, confirm that

webhook_url

is properly set on your chat agent configuration—not just at the account level.
