+     * @param string $visitor_id     Unique identifier of the visitor issued by Fingerprint Pro. (required)
+     * @param string $request_id     Filter visits by `requestId`.   Every identification request has a unique identifier associated with it called `requestId`. This identifier is returned to the client in the identification [result](https://dev.fingerprint.com/docs/js-agent#requestid). When you filter visits by `requestId`, only one visit will be returned. (optional)
+     * @param string $linked_id      Filter visits by your custom identifier.   You can use [`linkedId`](https://dev.fingerprint.com/docs/js-agent#linkedid) to associate identification requests with your own identifier, for example: session ID, purchase ID, or transaction ID. You can then use this `linked_id` parameter to retrieve all events associated with your custom identifier. (optional)
+     * @param int    $limit          Limit scanned results.   For performance reasons, the API first scans some number of events before filtering them. Use `limit` to specify how many events are scanned before they are filtered by `requestId` or `linkedId`. Results are always returned sorted by the timestamp (most recent first). By default, the most recent 100 visits are scanned, the maximum is 500. (optional)
+     * @param string $pagination_key Use `paginationKey` to get the next page of results.   When more results are available (e.g., you requested 200 results using `limit` parameter, but a total of 600 results are available), the `paginationKey` top-level attribute is added to the response. The key corresponds to the `requestId` of the last returned event. In the following request, use that value in the `paginationKey` parameter to get the next page of results:  1. First request, returning most recent 200 events: `GET api-base-url/visitors/:visitorId?limit=200` 2. Use `response.paginationKey` to get the next page of results: `GET api-base-url/visitors/:visitorId?limit=200&paginationKey=1683900801733.Ogvu1j`  Pagination happens during scanning and before filtering, so you can get less visits than the `limit` you specified with more available on the next page. When there are no more results available for scanning, the `paginationKey` attribute is not returned. (optional)
+     * @param int    $before         ⚠️ Deprecated pagination method, please use `paginationKey` instead. Timestamp (in milliseconds since epoch) used to paginate results. (optional)
