<div className="integrations-table">
  | Parameter   | Description                                                                                                                                                                                                                                            |
  | ----------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
  | Include All | If true, include all results, that is, do not paginate. Mutually exclusive with page and pageSize (they are ignored if includeAll=true is specified).                                                                                                  |
  | Level       | specifies whether multi-contact data is returned in a backwards-compatible, text format (level=0, default) or as multi-contact data (level=1).                                                                                                         |
  | Page        | Which page to return. Defaults to 1 if not specified. If you specify a value greater than the total number of pages, the last page of results is returned.                                                                                             |
  | Page Size   | The maximum number of items to return per page. Unless otherwise stated for a specific endpoint, defaults to 100. If neither pageSize nor page is specified, returns all rows in the sheet. If only page is specified, defaults to a page size of 100. |
  | Sheet ID    | Sheet ID of the sheet being accessed.                                                                                                                                                                                                                  |
