## Request

**Query parameters**

| Name | Type | Required | Description |
|---|---|---|---|
| `limit` | integer | no | Items per page (1 to 100, default 20). 1 to 100; default `20` |
| `cursor` | string | no | next_cursor from the previous page. Opaque; only valid with the same filters. up to 300 characters |
| `conversation_id` | string | no | Only messages of this conversation. |
| `direction` | string | no | inbound = from contacts, outbound = from the account. one of: `inbound`, `outbound` |
| `created_after` | string | no | Only messages after this time (ISO 8601). up to 40 characters; format date-time |
| `created_before` | string | no | Only messages before this time (ISO 8601). up to 40 characters; format date-time |

## Lists, filters and sorting

- Items per page: `limit` from 1 to 100, default 20 (MCP: default 20, maximum 50).
- Next page: send `next_cursor` of the answer as `cursor`. The cursor only works with the same filters. See [Pagination](https://docs.smartchat.marketing/en/concepts/pagination/).
- Filters: `conversation_id`, `direction`, `created_after`, `created_before`.
- Sorting: newest first (`created_at` descending, then `id` descending); no other order.
