# Getting Started

📝 This is a reference translation. In case of any discrepancy, the Japanese version prevails.

This Developer Center provides information about the Game8 Store: how it works, the process for starting sales, API specifications, and implementation methods.

## What is Game8 Store?

Game8 Store is a service for selling in-game items and Steam download keys within "Game8".

※ This Developer Center covers in-game item sales. If you would like to sell download keys (e.g., Steam keys), please contact us separately via the [Partner Inquiry](https://business.store.game8.jp/en/inquiry/) .

## Integration at a Glance

The path to launch consists of five steps: application & game registration → sales preparation → API integration → purchase testing & verification → go live.

To sell in-game items, publishers implement three required APIs (check, register, user_info) and one recommended API (stock).

There are two integration methods: reusing an existing API, or a new implementation. For details, see [Technical Integration Overview](https://developers.store.game8.jp/en/integration/) .
