NextJS call gtag("event") from api route

Question

I'd like to log an event on Google Analytics when an api route is opened.

My gtag implementation is as follows at the moment:

export const logEvent = ({ action, category, label, value }: LogEventProps) => {
  (window as any).gtag("event", action, {
    event_category: category,
    event_label: label,
    value: value,
  });
};

Problem is that it relies on a window for logs to be fired, which is undefined, understandably so, whenever I'm calling this method from an api route.

I couldn't find any valuable information on how to log an event from the server side.

A work-around might be to have the api redirect to a blank page that logs the event, but I don't love the idea and wonder if there's a better approach.
