How can I see exactly what was purchased as a result of a Facebook ad?

[AuroraBeam]

When viewing the results of my Facebook ads on the Facebook ad manager page, I can see that an ad resulted in X amount of purchases but I don't know how to see what products were purchased. Any advice would be greatly appreciated!
