Hey @mn1, sorry for the late response.
When you have a moment, please update your post to English (see post „Über die Kategorie“). It ensures you’ll get an answer quickly and allows everyone to follow along, especially those who aren’t fluent in German. Thanks for your understanding!
For your problem, could you help me out with the trace id of the failing request? This should be available in the details of the operation in make.com. 404 usually means that something does not exist. So 404 in this case could indicate that the company does not exist.
