About Private networking

Hi, I saw Railway has https://docs.railway.app/reference/private-networking Private network domain, do I understand correctly, that with this feature, I can use it to call between services as long as they are hosted on Railway? For example from the frontend service, I can call http://backend.railway.internal/api/posts to get the posts from backend?

yes, only if this call is made from the sever side of for example a nextjs app...

sidenote, you would need to set that backend to listen on a fixed port, and then use the port in the url when calling that internal domain
