GET /api/v1/chat/conversation

Get chat conversation for phone

Get the conversation with one phone number from the WhatsApp session, newest first.

Get the conversation with one phone number from the WhatsApp session, newest first. Page with limit, then pass the last message's id as cursorId and its direction as cursorFromMe.

Channels: QR (WhatsApp Web) channels only. On an official WhatsApp Cloud API number this request answers 409 with "error_code": "USE_MESSAGES_ARCHIVE" and a ready-made use.example URL — call that instead.

To read stored messages on any channel, use Message Archive → Get messages by date with phone=<number>.
