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:

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

        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);
        }
    }
