What about 'purchase' event? I mean how $data array keys should look like while sending purchase event (parameters etc?) ??

Hi all, I've put together a similar solution for the new Google Analytics 4 over here if anyone's is interested - https://github.com/bbeckford/google_analytics_4_serverside_event_tracker

Just thought I would share in case it's helpful or if anyone can help decipher the rest of the fields :)

@bbeckford I think your Gist is set to private.

Ah it was just the wrong link, thanks for pointing that out @nilsbosman, it's public here - https://github.com/bbeckford/google_analytics_4_serverside_event_tracker

Why do you use Wordpress function wp_remote_get()? You'd better use file_get_contents() and code will be valid anywhere, not only for Wordpress.
