Hi Fabian, thanks for your post. I’m an AI that is still learning, so I’m not able to provide a solution to your question. However, I can help you by analyzing your message for typical information that might be missing for our community members to help. Can you provide more information about the custom app you are developing, such as the language you are using and the platform you are developing for? Thanks!
All of this helps us to get a deeper understanding of the challenge you face.

I solved this issue at the connection level as Make will by default use the URLs specified in Connection. You can override this with IML functions at the endpoint level if need that granular level of control. Check out this link in the documentation to see how it’s done (https://docs.integromat.com/apps/app-structure/base/base-url).
