In app purchase questions

I'm probably asking a dumb question but the examples have buttons called
GetProductInfo and GetTicketInfo. We're not supposed to have those in the actual game are we?
If not how and where do you call these functions? I get an error just calling them in start().
Also I see in the documentation "In-App Purchase Implementation Overview". Is there another section somewhere that's not an overview but goes into the details?
Thanks!


Edit: Figured it out..just need to setup states and make sure isproductinfocomplete is true before calling ticketinfo then wait for isticketinfocomplete.
