### Answer I don't have information about recent changes or a changelog for the Chat API in the available sources. The documentation describes the current Chat API endpoints, including: - End Chat –

PATCH /end-chat/{chat_id}

to end an ongoing chat [(1) ]() - List Chat –

GET /list-chat

to retrieve all chats [(2) ]() - Update Chat –

PATCH

to update chat metadata and settings [(3) ]() - Create Chat Completion –

POST /create-chat-completion

to generate agent responses [(4) ]() If you're experiencing unexpected behavior or want to confirm recent updates, I'd recommend checking: - [Retell AI Documentation]() - [Contact Sales]() - [Retell AI GitHub]() Would you like me to provide a general answer about what might have changed, or details on how any specific Chat API endpoint works?

​ To learn more, see the sources I considered: [[1] End Chat](https://docs.retellai.com/api-references/end-chat) [[2] List Chat](https://docs.retellai.com/api-references/list-chat) [[3] Update Chat](https://docs.retellai.com/api-references/update-chat) [[4] Create Chat Completion](https://docs.retellai.com/api-references/create-chat-completion) ​
