I'm trying to load the unprinted parts via the API (https://www.thegamecrafter.com/api/part?_items_per_page=100&_page_number=1), but I get a code 450 error "you must be an admin to do that".
Is this a bug? Or how can I get access to the Parts API?
This is not a bug. We've changed the API for searching Parts. You can read more about it in the developer documentation.
