# Chat methods

Methods for retrieving and deleting persisted chat history. Realtime delivery uses `send()` — see [Realtime methods](/product-docs/reference/realtime-methods.md).

## Methods

| Method                       | Server code | Description                                         |
| ---------------------------- | ----------- | --------------------------------------------------- |
| `fetchChatHistory()`         | `201`       | Request conversation history for given participants |
| `deleteChatHistoryMessage()` | `202`       | Delete a single stored chat message                 |

## `saveHistory` flag

`send()` accepts `saveHistory` (default `true`). Set `saveHistory: false` for ephemeral messages that should not appear in history queries.
