👋 Hello Jayant, I understand your problem. You have not sent any parameters in Ad Payment Info ( email, phone, country, city, zipcode, etc ). Which is why this problem is showing you. You do not have set up all events using the Facebook & Instagram app and it is not possible to optimize this event. Because of which you can't optimize all evens, if you use Google Tag Manager you can customize all evens parameters and solve all problems. 👉 https://dev-freelancer-nurumiah016.pantheonsite.io/facebook-pixel-conversion-api-tracking/
