## List all chats

`client.Chats.ListChats(ctx, query) (*ListChatsPagination[Chat], error)`

**get** `/v3/chats`

Retrieves a paginated list of chats for the authenticated partner.

**Filtering:**

- If `from` is provided, returns chats for that specific phone number
- If `from` is omitted, returns chats across all phone numbers owned by the partner
- If `to` is provided, only returns chats where the specified handle is a participant

**Pagination:**

- Use `limit` to control page size (default: 20, max: 100)
- The response includes `next_cursor` for fetching the next page
- When `next_cursor` is `null`, there are no more results to fetch
- Pass the `next_cursor` value as the `cursor` parameter for the next request

**Example pagination flow:**

1. First request: `GET /v3/chats?from=%2B12223334444&limit=20`
1. Response includes `next_cursor: "20"` (more results exist)
1. Next request: `GET /v3/chats?from=%2B12223334444&limit=20&cursor=20`
1. Response includes `next_cursor: null` (no more results)
