We're currently trying to set up the e-commerce tracking in Google Analytics. Google gives us the following example code:

Code:
gtag('event','purchase',{
  "transaction_id":"24.031608523954123",
  "affiliation":"Google online store",
  "value":23.07,
  "currency":"USD",
  "tax":1.24,
  "shipping":0,
  "items":[
    {
      "id":"P12345",
      "name":"Android Warhol T-Shirt",
      "list_name":"Search Results",
      "brand":"Google",
      "category":"Apparel/T-Shirts",
      "variant":"Black",
      "list_position":1,
      "quantity":2,
      "price":'2.0'
    },
    {
      "id":"P67890",
      "name":"Flame challenge TShirt",
      "list_name":"Search Results",
      "brand":"MyBrand",
      "category":"Apparel/T-Shirts",
      "variant":"Red",
      "list_position":2,
      "quantity":1,
      "price":'3.0'
    }
  ]
});
Is there somewhere we need to put this or is this covered automatically by entering the correct ID in "Google Ads conversion ID" in General > Integrations > Google?
