Doing redirects from non Drupal site. In attempt to list path in 404, module doesn't fetch full query, just the base

I am moving a site, from old PHP only site to Drupal.
So I am trying to get 404 for the url so I can have it in admin and make a redirect. So I am accessing new drupal site, with old query like

https://develop.example.com/de/staticPage.php?page=customerCare&service=...

but system only registers

https://develop.example.com/de/staticPage.php

so I cant make redirects as I dont know which query it was. My plan was to hit the site with hundreds of old queries and then make redirects for them (there are no possible patterns that match old and new so I can only do it like that) but this will not work as system only gets base of url.
