In-app purchase (IAP) allows the developer to integrate an Ovi Store purchasing feature into his Java application in a simple and seamless manner. End users (consumers) can purchase additional digital content or services directly from their application, without having to leave the application.
With in-app purchase, end users can easily buy additional digital content without having to leave your application.
Developers can either:
Unlock the additional content from within your application – for example, unlock additional game levels, or switch from free demo access to paid access.
Deliver additional content from a back-end server that you manage – for example, download a city travel guide from your serve.
For more details on In-app purchase, see the In-app purchase section in Java Developer's Library.
Before you begin to implement In-app purchase feature in the application, it is necessary to get familiarize with In-app purchase at large and the basic design guidelines for in-app purchase. Developers also need to register as an Ovi publisher and familiarize with the Ovi publishing guidelines.
