# AI skill for In-App Purchasing

> Migrate to and integrate Unity IAP v5 with an AI skill you install in your preferred AI assistant.

Starting in IAP version 5.3.0, the In-App Purchasing (IAP) package includes an AI skill that helps you migrate to and integrate Unity IAP v5. You install the skill into a compatible AI assistant, then prompt it in plain language to perform a migration or integration. If you subscribe to Unity AI Assistant or Unity AI Desktop, the skill is built in and requires no installation. The skill follows Unity's current v5 procedures instead of writing code from memory.

The following pages explain what the skill does, what it can build for you, and how to install and run it. For the full set of code changes involved in moving to v5, refer to [Upgrade from IAP v4 to v5](./upgrade-to-iap-v5.md).
