If you need to track conversions insert this pixel in your «thank you page»:
If you want to track «Add to carts», work with this event pixel:
If you want to track more events, like each step of checkout process, you can replace «conversion_type» field with each stage name. You can add variables as you need (email, city,…)
It’s very important to remember that the conversion or microconversion pixel must be added BEFORE the tracking code is added
