How to add a tracking pixel for only 1 product

Hello Folk ,

i would like to test an adword campaign for promote only one product, i’m using an ads tracking script “Ads Trackz Gold”, i would like to insert the tracking pixel , as i can see for now it’s possible only to insert a tracking code wich will alway pop whatever products is bought , which is not what i want

i have read that shopify have a dedicated api language and maybe there is a snippet to do this ?

could you tell me what would be the way to do it please?

thank you very much
