Facebook iOS update : integrated the conversions APIs with native php

The Facebook Conversion API events are more powerful than the Facebook Web Pixels. The Conversion API event gets fired through backend logic. you can use the ajax call from the front end, and check the event triggers on the Facebook panel

Facebook Pixel Conversion API

https://developers.facebook.com/docs/marketing-api/conversions-api/

you can generate the access token from https://business.facebook.com/event_manager select your site and generate the Facebook pixel

javascript ajax function and you can simply call this ajax function where you want to trigger pixel

Function Call

let event_id = d.getTime(); 
fbq_custom("PageView", window.location.href, {event_id: 'PageView-'+event_id}, {event_id: 'PageView-'+event_id}) }

Function Definition

function fbq_custom(trace = 'PageView', source_url = '', data = {}){

    data.trace = trace;
    data.source_url = source_url
    $.ajax({
        url: "/conversionAPI/",
        data: data, 
        type: "post",  
        success: function (data) {
            console.log(data);
            console.log("server event test");
        }
     });
}

I just use this package
