How to access Team Folders with Java API ?

Hello amedeomantica,

Can you clarify if this is a team-linked app, or a user-based app being linked to a team-based account?

In either case, I would suggest our namespace reference guide as a resource that may help with resolving this:

https://www.dropbox.com/developers/reference/namespace-guide

Of specific interest (if you are using a team-linked app) will be the namespacesList() and namespacesListContinue() methods to retrieve Team Folder namespace IDs:

DbxTeamClientV2 client = new DbxTeamClientV2(config, ACCESS_TOKEN);
TeamNamespacesListResult namespaces = client.team().namespacesList(); // with an optional limit param

Within the results of that call, you can examine the NamespaceType value to determine what kind of folder it is:

for ( NamespaceMetadata namespace : namespaces.getNamespaces()) {
    if ( namespace.getNamespaceType() == NamespaceType.TEAM_FOLDER ) {
        System.out.println("Team Folder: " + namespace.getName());
    }
}

And once you have that you can use the namespace ID ( getNamespaceId() ) in other calls to traverse the Team Folder. Be aware you may need to prefix the namespace ID with "ns:" for it to be an acceptable path parameter to methods like listFolder() and you will need to impersonate (asMember()) users with appropriate access to any given folder to list its contents.

Hope that helps,

-Chuck

Hi @chirstius,

Mine is a team linked app with "Team member file access"

I followed your suggestion in order to get the namespaces list and find the team folder.

Hovewer if I try to list team folder files I go into error

Caused by: com.dropbox.core.v2.files.ListFolderErrorException: Exception in 2/files/list_folder: {".tag":"path","path":"not_found"}
	at com.dropbox.core.v2.files.DbxUserFilesRequests.listFolder(DbxUserFilesRequests.java:1425)
	at com.dropbox.core.v2.files.DbxUserFilesRequests.listFolder(DbxUserFilesRequests.java:1466)

If I try any other namespace ( member folders, shared folders ) everything works.

Any idea ?

Are you certain the member ID you are using to access the team folder actually has access to it? You may need to switch to a different user via asMember(). Can you validate that first? Then we can dig a little deeper...

Thanks!

amedeomantica,

Are you able to access other Team Folders as that user? Is it just a single specific folder that is failing or all Team Folders?

Also, if you wouldn't mind, can you post a sample of the code you are using to list the Team Folder and a recent error response?

Thanks,

-Chuck

Hi chirstius,

Here the relevant code:

private DbxTeamClientV2 client;

DbxRequestConfig config = DbxRequestConfig.newBuilder("something").build();

client = new DbxTeamClientV2(config, accessToken);

public DbxClientV2 memberClient() {
    return client.asMember("dbmid:userIdWithFullAccess");
}

public NamespaceMetadata teamFolderNameSpace() throws DbxException {

    TeamNamespacesListResult namespaces = client.team().namespacesList();

    for ( NamespaceMetadata namespace : namespaces.getNamespaces()) {
        //this correctly list all the available namespaces, including the team folder
        log.info(namespace.getName() + "/" + namespace.getNamespaceId));
    }

    //correctly returns the teamfolder
    for ( NamespaceMetadata namespace : namespaces.getNamespaces()) {
        if ( namespace.getNamespaceType() == NamespaceType.TEAM_FOLDER ) {
            return namespace;
        }
    }
    return null;
}

then:

public Result test() throws Exception {

    final NamespaceMetadata namespaceMetadata = dropBoxConnection.teamFolderNameSpace();
    if(namespaceMetadata != null) {
        String namespaceId = namespaceMetadata.getNamespaceId();

        // MEDIA folder exists and I access it from web/desktop (I'm the same user as memberClient)
        // But is not working from here
        // also tried without "MEDIA" (listing team folder root), no luck
        String path = "ns:" + namespaceId + "/MEDIA";

        //This works, putting any namespace ID (I can access), except main team folder
        //String path = "ns:ANY_OTHER_NAMESPACE_ID_I_CAN_ACCESS";

        log.info(path);

        final ListFolderResult listFolderResult = dropBoxConnection.memberClient().files().listFolder(path);
        listFolderResult.getEntries().forEach(r -> {
            log.info(r.getName());
        });
    }

    return ok("ok");
}

error:

Caused by: com.dropbox.core.v2.files.ListFolderErrorException: Exception in 2/files/list_folder: {".tag":"path","path":"not_found"}
	at com.dropbox.core.v2.files.DbxUserFilesRequests.listFolder(DbxUserFilesRequests.java:1425)
	at com.dropbox.core.v2.files.DbxUserFilesRequests.listFolder(DbxUserFilesRequests.java:1466)
	at controllers.HomeController.test(HomeController.java:133)

chirstius it worked (withPathRoot) !! Thank you!

Glad to hear it, don't hesitate to reach out again if there is anything else you need.
