# Query parameters

You can modify behavior of some operations by using the following query parameters.

| Query Parameter | Type | Description | More Info |
|  --- | --- | --- | --- |
| `accessApiLevel` | number | Allows COMMENTER access for inputs and return values. For backwards-compatibility, VIEWER is the default. For example, to see whether a user has COMMENTER access for a sheet, use accessApiLevel=1. |  |
| `allowPartialSuccess` | boolean | If set to `true`, allows bulk operations to process even if one or more operations are invalid for some reason, for example, `allowPartialSuccess=true`. | [Bulk Operations](/api/smartsheet/guides/advanced-topics/scalability-options#bulk-operations) |
| `include` or `exclude` | string | When applicable for a specific object, various `include` or `exclude` parameters are available, for example, `include=format`. | Object reference or [cell formatting](/api/smartsheet/guides/advanced-topics/cell-formatting) |
| `includeAll` | boolean | If set to `true`, the operation returns all the items in a single response.   **Note:** The `includeAll` parameter is deprecated for several operations. See the operation documentation or the [Changelog](/api/smartsheet/changelog) for details. | [Offset-based pagination](/api/smartsheet/guides/basics/pagination#offset-based-pagination) |
| `lastKey` | string | If your previous call to the endpoint indicated more items remained (that is, the response included a `lastKey` property with a token value), set the `lastKey` parameter to that token to retrieve the next page of items. If you omit `lastKey`, the endpoint returns the first page of results. | [Token-based pagination](/api/smartsheet/guides/basics/pagination#token-based-pagination) |
| `level` | number | Use for complex objects. | [Working with Complex Objects](/api/smartsheet/guides/advanced-topics/complex-column-types-and-compatibility) |
| `numericDates` | boolean | If set to `true`, allows you to input or receive dates in numeric format, for example, `numericDates=true`. | [Dates and Times](/api/smartsheet/guides/basics/dates-and-times) |
| `maxItems` | integer | The maximum number of items to return per page.   The `maxItems` parameter is available for operations that use token-based pagination. | [Token-based pagination](/api/smartsheet/guides/basics/pagination#token-based-pagination) |
| `page` | string | Specifies which page of items to return in the response.   **Note:** The `page` parameter is deprecated for several operations. See the operation documentation or the [Changelog](/api/smartsheet/changelog) for details. | [Offset-based pagination](/api/smartsheet/guides/basics/pagination#offset-based-pagination) |
| `pageSize` | number | The maximum number of items to return per page.   **Note:** The `pageSize` parameter is deprecated for several operations. See the operation documentation or the [Changelog](/api/smartsheet/changelog) for details. | [Offset-based pagination](/api/smartsheet/guides/basics/pagination#offset-based-pagination) |
