As Blake said, yep. Here's some more detail.

Public, non-authenticated access - Public Portal Add On to WebLink

(Bunch of customization options) - https://www.laserfiche.com/solutionexchange/how-to-enhance-your-laserfiche-weblink-portal-with-search-urls/

Authenticated/Controlled access - WebLink and WebAccess allow read only authentication through Active Directory. You would have to allow this to pass through, settings in IIS and your network may require kerberos depending on the setup.  There may also be web browser specific settings to manage depending on which type. For example FireFox requires configuration to allow Windows Authentication to pass through without a prompt.

Here's a glimpse at some code i just wrote to update an external SQL database with the URL of a performed search on the repository using the SDK. You can also use Laserfiche Workflow to do the same thing.

Console.WriteLine("Enter path to operate on: (include \\ at beginning)");
                string lfspath = Console.ReadLine();

                lfqlCommand.CommandText = "select e.entry_name, e.entry_id from lf.entry e where is_descendantof(e.path, '" + lfspath + "') = 1 AND e.type='document'";
                LfDataReader reader = lfqlCommand.ExecuteReader();
                if (reader.HasRows) // non=zero result set
                {
                    Console.WriteLine("Total Entries: " + reader.RecordsAffected.ToString()); // show total
                    while (reader.Read())
                    {
                      
string url = "http://lfserver/Weblink/DocView.aspx?id=" + reader["e.entry_id"].ToString();

In a more concise way, something has to authenticate or log in to view a document regardless of the URL or using WebAccess or Weblink.

If using weblink, in the weblink administrator utility you must setup a directory to:

a. Use automatic windows authentication (which passes through the browser making the request)

b. Use a singular laserfiche account to anonymously authenticate everyone (configured to consume the public portal license)

The windows authentication method is also able to be set to automatic for Web Access. Again, depending on your network, Kerberos may be required. Laserfiche has produced some white papers on how to set that up too.

Then you can pass constructed URLS either by document ID, or populating a URL which returns a search query, to view documents without requiring the user to manually login.
