I built a plugin wordpress (Events Tracker), its my first plugin.
I think is simple plugin but usefull.
You can search and then download with keyword "Events Tracker" in plugin directory or visit to https://id.wordpress.org/plugins/ads-pixel
It's help you to setup pixel id to your wordpress, Just need pixel id only and paste to setting. Default event type is "PageView", now you can't choose other type but you can do it in the next release.
I hope this help you too, don't hestitate to advise to me.
Thanks
