Hello I have a library in a sharepoint where has been added more columns than the ones use for default. As you can imagine have another folders with documents inside of each folders.

The Job that I'm creating needs to identify if in the main folder has bee added something new in the columns ; for example in the column status that is more at the right; and then trigger the process. Until there all good. What the process do is go inside the folder with and extract all the information in there.

For one list like the one previous showed, I'll defetively use the function get items. But as you know get items can't be used to extract that informtion from a subfolder. I tried List folder option but I only get the list of the files; no more related information of the rest of the columns there. I also tried used an HTTP Request with the next uri: /_api/web/Lists/GetByTitle('Internal Policies')/Items?$expand=Folder&$select=Title,FileLeafRef,Folder/ServerRelativeUrl . but again only get information related with the files. Now the question is how can I get the rest of the information listed in the columns in an specific subfolder just how you normally do it using the funtion get items? I need these information because more at the right each file has listed sharepoint group names that I need to notify the users.
Thanks for any help that you can provide
