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 that, 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
