Valid keys are `createdDate`, `folder`, `lastViewedByMeDate`, `modifiedByMeDate`, `modifiedDate`, `quotaBytesUsed`, `recency`, `sharedWithMeDate`, `starred`, and `title`. Each key sorts ascending by default, but may be reversed with the `desc` modifier. Example usage: ?orderBy=folder,modifiedDate desc,title. Please note that there is a current limitation for users with approximately one million files in which the requested sort order is ignored. |\n| `pageToken` | `string` Page token for children. |\n| `q` | `string` Query string for searching children. |\n\n### Request body\n\nThe request body must be empty.\n\n### Response body\n\nA list of children of a file.\n\nIf successful, the response body contains data with the following structure:\n\n| JSON representation |\n|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| ``` { \"items\": [ { object (/workspace/drive/api/reference/rest/v2/children#ChildReference) } ], \"nextPageToken\": string, \"kind\": string, \"etag\": string, \"selfLink\": string, \"nextLink\": string } ``` |\n\n| Fields ||\n|-----------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| `items[]` | `object (`[ChildReference](/workspace/drive/api/reference/rest/v2/children#ChildReference)`)` The list of children.

This will be absent if the end of the children list has been reached. If the token is rejected for any reason, it should be discarded, and pagination should be restarted from the first page of results. |\n| `kind` | `string` This is always `drive#childList`. |\n| `etag` | `string` The ETag of the list. |\n| `selfLink` | `string` A link back to this list. |\n| `nextLink` | `string` A link to the next page of children. |\n\n### Authorization scopes\n\nRequires one of the following OAuth scopes:\n\n- `https://www.googleapis.com/auth/docs`\n- `\n https://www.googleapis.com/auth/drive`\n- `\n https://www.googleapis.com/auth/drive.appdata`\n- `\n https://www.googleapis.com/auth/drive.file`\n- `\n https://www.googleapis.com/auth/drive.meet.readonly`\n- `\n https://www.googleapis.com/auth/drive.metadata`\n- `\n https://www.googleapis.com/auth/drive.metadata.readonly`\n- `\n https://www.googleapis.com/auth/drive.photos.readonly`\n- `\n https://www.googleapis.com/auth/drive.readonly`\n\nSome scopes are restricted and require a security assessment for your app to use them.
