SharePoint 2013 REST API Methods to Get File Names from Folders

Question

Accessing the SharePoint 2013 API, I have been trying to get files names in each folder in a library and getting errors. I am using Alteryx.

DownloadData Error:

{"error":{"code":"-2147024809, System.ArgumentException","message":{"lang":"en-US","value":"Value does not fall within the expected range."}}}<

My URLs are below:

https://team.global.ABCCompany/sites/ABCDataLake/_api/web/GetFolderByServerRelativeUrl('/FolderName')/Files

And

https://team.global.ABCCompany/sites/ABCDataLake/_api/sp.appcontextsite(@target)/web/getfolderbyserverrelativeurl('FolderName')/Files

1. Might you be able to spot a mistake?
2. In the 2nd one, should I be filling in anything to replace "@target"?
3. Is there a preferred method, assuming one works?

Many thanks as always.

Answer 1

You need to provide the "Folder URL" which is a server relative path of a folder. Let's say you need the file names from "Folder1" folder of "ABCLibrary" document library.

URL: https://team.global.ABCCompany/sites/ABCDataLake/_api/web/GetFolderByServerRelativeUrl('/ABCLibrary/Folder1')/Files

In the second one, you are making a cross-domain requests, so you have added SP.AppContextSite(@target) in which you need to pass ?@target='<host web url>' to the endpoint URI.

URL: https://team.global.ABCCompany/sites/ABCDataLake/_api/sp.appcontextsite(@target)/web/getfolderbyserverrelativeurl('/ABCLibrary/Folder1')/Files?@target='https://team.global.ABCCompany/sites/ABCDataLake'

Answer 2

You can use SharePoint REST API endpoint in below format to get the files from specific folder inside document library:

https://contoso.sharepoint.com/sites/SPConnect/_api/web/GetFolderByServerRelativeUrl('/sites/SPConnect/Shared%20Documents/Folder1')/Files

You can even get properties associated with files using single API call like:

https://contoso.sharepoint.com/sites/SPConnect/_api/web/GetFolderByServerRelativeUrl('/sites/SPConnect/Shared%20Documents/Folder1')/Files?$expand=ListItemAllFields
