Questions tagged [in-app-purchase]

In-app purchase (IAP) usually refers to the acquisition of a feature for an application from within the application itself or the buying of digital goods from within an application. Use this tag for questions about writing code for the buying process. Questions about app-store policies or about specific transactions are off-topic on Stack Overflow and should not be posted.

In-app purchases (IAP) are digital goods which, when bought from within an app, often either unlock new features, enable the user to skip mundane tasks or provide additional content.
Such purchases were made popular by Apple's iOS SDK, iPhones, iPod Touches and iPads, but are not limited in any way to these platforms.

Don't ask questions about the transaction process itself, except where it pertains to coding problems. Remember that Stack Overflow cannot answer questions specific to Customer Support

When posting an in-app purchase with Apple they ask for a screenshot to be included before going to review. What kind of screenshots do they want? My in-app purchase unlocks some of the lite version, I'm not sure what Apple wants to see here.
