Messages.modify method allows you to make changes to the message. You need to modify the message and remove the UNREAD label. The message will then appear to be read

public static Message ModifyMessage(GmailService service, String userId,
      String messageId, List<String> labelsToAdd, List<String> labelsToRemove)
  {
      ModifyMessageRequest mods = new ModifyMessageRequest();
      mods.RemoveLabelIds = "UNREAD";

      try
      {
          return service.Users.Messages.Modify(mods, userId, messageId).Execute();
      }
      catch (Exception e)
      {
          Console.WriteLine("An error occurred: " + e.Message);
      }

      return null;
  }

Not on access

This method requires one of the following scopes of access
