How It Works
Meta counts a customize product event when a visitor personalizes a product after interacting with your ad within the attribution window. This includes selecting size, color, adding engraving, monogramming, or any other customization option. The event is captured via the Meta Pixel or Conversions API when the shopper completes the customization step.
