Redirect from an external URL

[marcocoelho]

Guys, I need a help.
I need to do a Universal Angular redirect to an external URL.

When returning the API from an id that does not exist I need to send to an external URL of my app.

As it runs on the server, I can't use the default redirect.
Has anyone of you ever been through this? How to make? Can you help me please?
