Yo!

I’ve cracked it! Basically, you was on the right track with that article you found (this one: [custom event GA4](https://www.delasign.com/blog/custom-ga-event-reactjs-gatsbyjs/)), you just need to tweak it a bit.

In **step 2**, switch up the ‘TrackGoogleAnalyticsEvent’ method like this:

`
const TrackGoogleAnalyticsEvent = (
category,
event_name,
label,
data
) => {
console.log(“GA event:”, category, “:”, event_name, “:”, label);

let event_params = {
category,
label,
…data
};
// This will send your GA4 Event
ReactGA4.event(event_name, event_params);
};
`

Then, on the client side, just pop the following code in:

`
TrackGoogleAnalyticsEvent(
“game_over”,
“message shown”,
window.location.pathname + window.location.search,
{ id: 1234, username: “john” }
);
`

Here’s a little tip: you can stuff as many parameters as you like into the JSON object.

Take a look at the [‘react-ga4’ package](https://github.com/codler/react-ga4) for more deets.
