Sharepoint 365 Rest Api cannot see any document or element

Question

I'm using Sharepoint online (included in office 365) I'd like to use sharepoint as a document repository.

I've created some test folders&Docs on my created test site:

I have created my auth token with this: https://www.ktskumar.com/2017/01/access-sharepoint-online-using-postman/

With the Rest API V1 and postman When I list the root folders as described here I have this kind of error:

Server relative urls must start with SPWeb.ServerRelativeUrl

So as if I remove the first "/" like this

/_api/web/GetFolderByServerRelativeUrl('Documents')/Folders

I get a 200 response with an empty array 😕

I did browse aproximatly every endpoint of this HATEOS list but did not find any interesting data in return

/sites/Contentieux/_api/web/lists

Where my created documents could be hidden?

EDIT: See the full response in comments of answered post

Answer 1

It is "server" relative, not "site" relative. The server relative URL for your document library is /sites/Contentieux/Documents. So your API call would be:

https://<<your tenant>>.sharepoint.com/sites/Contentieux/_api/web/GetFolderByServerRelativeUrl('/sites/Contentieux/Documents')/Folders

Answer 2

You need to pass the URL related to your site URL. Check below examples:

To get folders in document library:

http://site url/_api/web/GetFolderByServerRelativeUrl('/sites/SiteName/Shared Documents')/folders

To get files in document library/folder:

http://site url/_api/web/GetFolderByServerRelativeUrl('/sites/SiteName/LibraryURL/Folder Name')/Files

To get all Files and Folders in one call:

http://site url/_api/web/GetFolderByServerRelativeUrl('/sites/SiteName/Shared Documents')?$expand=Folders,Files

Reference: Get all Files and Folders in one call
