Sharepoint API Error ID3035

Question

Sharepoint API Error ID3035

Gabriele Iodice 101

Hello,

I am trying to download a file using the Sharepoint API.
I get the Access Token then I use the following API to read a folder (or any other API to download a file), but I always have the following error

GET https://{site_url}/_api/web/GetFolderByServerRelativeUrl('/Shared Documents')
Auth: Bearer {toke}

as explained here https://learn.microsoft.com/en-us/sharepoint/dev/sp-add-ins/working-with-folders-and-files-with-rest

{"error_description":"ID3035: The request was not valid or is malformed."}

The authentication token must be correct because when I change it I have a different error.

Thanks!
Gabri

Hi @MichaelHan-MSFT ,
thanks for your help.

You were right: the authentication was the problem. But the documents you shared were not exactly what I was looking for. This is the thing that helped me a lot:

Hi @Gabriele Iodice ,

I'm not an expert with java. From your code, you are acquiring AAD token using app client ID and secret. This way is to authenticate with Graph API. And It would not work for SharePoint Rest API.

For SharePint Rest API with AAD app, you need to get the token with the certificate opion. You can refer to this article for more: https://learn.microsoft.com/en-us/sharepoint/dev/solution-guidance/security-apponly-azuread

Hi @Gabriele Iodice ,

How did you retrieve the Access Token? Please share more details. Use SharePoint APP or AAD APP?

For SharePoint APP access token: https://global-sharepoint.com/sharepoint-online/in-4-steps-access-sharepoint-online-data-using-postman-tool/
For Azure AD APP access token: https://www.ludovicmedard.com/use-postman-and-azure-ad-to-send-rest-request-to-sharepoint-online/

Hi MichaelHan,
so basically I have used the msal4j lib in a Java Maven Project.

I configured it as follow:

final String authenticationType = "ServicePrincipal";
final String clientId = "xxxxxxx";
final String appSecret = "xxxxxxxx";
final String tenantId = "xxxxxxx";

public static final String authorityUrl = "https://login.microsoftonline.com/";
public static final String scopeUrl = "https://site_url/.default";


ConfidentialClientApplication app = ConfidentialClientApplication.builder(
                    clientId,
                    ClientCredentialFactory.createFromSecret(appSecret))
                    .authority(Config.authorityUrl + tenantId)
                    .build();

        ClientCredentialParameters clientCreds = ClientCredentialParameters.builder(
                Collections.singleton(Config.scopeUrl))
                .build();

        // Acquire new AAD token
        IAuthenticationResult result = app.acquireToken(clientCreds).get();

Hi sadomovalex,
thanks for your answer.

I am retrieving the token using the ServicePrincipal approach yes.

My only clue for now is this https://answers.microsoft.com/en-us/msteams/forum/msteams_tff-msteams_file-msteams_findfile/id3035-the-request-was-not-valid-or-it-is/b8d93f2d-6524-4623-a719-431b272b4416
