How to set up FB pixel if I´m going to set up Conversiones API with GTM

[Pelix1000]

Hi,
I set up a FB pixel on my website to track 5 events and those are working properly. Now I want to set up conversion API with GTM, but I don´t have a clue how to. My first questions is if I could maintain pixel on my website or I have to migrate pixel tracking to GTM. Another question is if pixel can still on my website while conversion API is through GTM: do I have to set up the same events in both parts: GTM and Facebook. (I just have one domain, one website, one pixel)

Or please tell me what is the best way to do this, I have read all day about this and I´m still lost.

Hi You can maintain the pixel you setup in your website as it is. If you want to take the advantages of first party tracking then you can setup conversion API through GTM. Yes you can send same events from both the pixel and conversion API . If you do so then you have to send event ID as a event parameter from both pixel and conversion API. It will help meta to deduplicate the events. Otherwise the same event will be registered twice. Meta recommends to setup both the pixel and conversion API.
