Hi,

I am creating a web application project and use Dropbox API for storing my Users file, where I want a user to upload their file after login in there account in a website (not a dropbox) and brows and upload file from the system and after submitted by the user this file is stored in a company Dropbox account with an automatically created folder of username 

I stuck here from last 4 day and already read the various document but I didn't get any help related to my specific requirements.

Please help if anyone have the solution 

Thank you in Advanced

Dropbox does offer an API you can use for uploading and listing files, among other operations. You can find everything you need to get started with the Dropbox API, including documentation, tutorials, and SDKs here:

https://www.dropbox.com/developers

I recommend using one of the official SDKs, if possible, and following the respective tutorial to get started:

https://www.dropbox.com/developers/documentation

I also recommend reading the OAuth guide to understand how the authorization process works:

It sounds like your question is about getting the input stream for a local file. This isn't directly related to Dropbox itself, so I'm afraid I can't be of much help with this. You may be better suited by referring to general Java IO documentation or guides for interacting with the local file system.

By the way, I redacted it from your post, but for the sake of security, you should disable that access token that you posted. You can do so by revoking access to the app entirely, if the access token is for your account, here:

https://www.dropbox.com/account/connected_apps

Or, you can disable just this access token using the API:

https://www.dropbox.com/developers/documentation/http/documentation#auth-token-revoke

You can do so in the Java SDK itself:

https://dropbox.github.io/dropbox-sdk-java/api-docs/v3.0.x/com/dropbox/core/v2/auth/DbxUserAuthReque...

Or in the API v2 Explorer if you want:

import com.dropbox.core.v2.DbxClientV2;
import com.dropbox.core.v2.files.FileMetadata;
import com.dropbox.core.v2.files.ListFolderResult;
import com.dropbox.core.v2.files.Metadata;

import java.io.IOException;

public class DbxUpload {
    private static final String ACCESS_TOKEN = "<REDACTED>";

    public static void main(String args[]) throws DbxException, IOException {
        // Create Dropbox client
        DbxRequestConfig config = new DbxRequestConfig("dropbox/java-tutorial", "en_US");
        DbxClientV2 client = new DbxClientV2(config, ACCESS_TOKEN);

        // Get current account info
        FullAccount account = client.users().getCurrentAccount();
        System.out.println(account.getName().getDisplayName());

        // Get files and folder metadata from Dropbox root directory
        ListFolderResult result = client.files().listFolder("");
        while (true) {
            for (Metadata metadata : result.getEntries()) {
                System.out.println(metadata.getPathLower());
            }

            if (!result.getHasMore()) {
                break;
            }

            result = client.files().listFolderContinue(result.getCursor());
        }

        // Upload "test.txt" to Dropbox
        try (InputStream in = new FileInputStream("D:/RUNNING.txt")) {
            FileMetadata metadata = client.files().uploadBuilder("/RUNNING.txt")
                .uploadAndFinish(in);
        }
    }
}

I'm having the same issue. Did you ever get this solved? And if so, do you have a site I can reference for your example and maybe reach out to you on!?
