​ To learn more, see the sources I considered: [[1] List Chat](https://docs.retellai.com/api-references/list-chat) [[2] List Chat Agents](https://docs.retellai.com/api-references/list-chat-agents) ​

### Answer Based on the available documentation, the List Chat endpoint (

GET /list-chat

) does not support filtering by phone number or any other query parameters. [(1) ]() The documentation shows it simply returns all chats without filter options:

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

For comparison, the List Chat Agents endpoint does support pagination parameters (

pagination_key

,

pagination_key_version

) , but the List Chat endpoint does not document similar filtering capabilities. [(2) ]() Currently, you would need to retrieve all chats and filter client-side, or you may want to reach out to Retell support to request this as a feature: - [Contact Sales]() - [Retell AI GitHub]()
