To configure a dynamic folder search based on a query string, set the folderId key to null, and for the folderIdQSField key specify a query string field to hold the Folder Number. For example:
“folderId”: null,
“folderIdQSField”: “folderNum”
Then, include the created field in the query string appended to the URL, and set its value to the ID number of the folder to search. Following the previous example, a URL with the following query string could be used to search folder #1358:
?folderNum=1358
