When the user goes to the Cart page, we have a CTA button that allows then to 'upgrade' their product to a more deluxe version. Whether they decide to upgrade or not, they will be sent to an Information page where they enter their credit card and account information. Finally, the will reach an Order Confirmation page.
I have already applied analytics to the 'upgrade' CTA button to track when they have used this feature. Now I am trying to track whether the user has successfully went through the entire checkout flow with the an upgraded product. I was thinking of tracking this with a Google Analytics Custom Dimension, but I am unsure if this will work. I was hoping to get feedback before I implement my idea.
Requirements: Tracks if the user reaches the Order Confirmation page with an 'upgraded' product they have upgraded in the Cart page
Proposed Solution: Fire a Custom Dimension when the user upgrades the product in the Cart page. I am unsure how to verify if the user reaches the Order Confirmation page with the 'upgraded' product though.
