Overview

This document explains how to activate In-App Purchasing (IAP).

The Unity IAPAbbreviation of Unity In App Purchase

package provides coded and codeless approaches that you set up to: - Allow users to buy items in your games. - Connect to stores so that you can obtain revenue from these purchases.

Here is an overview of the steps:

  • Define your In-app purchase strategy for this game.
  • Setup your project as a Unity service.
  • Activate IAP to automatically install the package.
  • Configure settings.
  • Create and catalog your the in-game items that you want to sell.
  • Use the Codeless IAP button to give users a way to buy items. Then, once you have the logic working, consider customizing the button look and feel. Or use the scripted IAP for a rich API to enhance this process.  Demo
  • Connect your app to the relevant app-stores, such as Google, Apple, or Android.
  • Add items to the stores.

Put it all together:

  • Configure your IAP using guidance from this doc, support, and the IAP forum.
  • Test everything.
  • Make it live.

You can also do many of these steps, or fine tune what you create, with the In-App Purchasing API.

Getting Started

Note: The Samsung Galaxy store is now obsolete and is no longer supported in the Unity In-App Purchasing package 4.0.0 and higher. This guide to configure the Samsung Galaxy store only applies to the IAP package version 3.1.0 and earlier. If you’re using the Unity IAP package 4.0.0 and higher and want to implement a Samsung Galaxy store, use the Unity Distribution Platform instead.

  1. Open your Unity project in the Unity Editor.
  2. Choose Window\General\Services. The services window will appear.
  3. Create a Project ID, then connect the project to an organization.
  4. Answer the COPPA(Children’s Online Privacy Protection Act) COPPA is a US law that applies to apps that collect personal information and are targeted to children under the age of 14. More info

This will automatically install the IAP package from the package manager, providing you with new features and menu items to help you manage IAP.

Next Steps

Define your In-App Purchase strategy

Your task will be to create items for players to buy and obtain their identifiers.

To make this happen behind the scenesA Scene contains the environments and menus of your game. Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. More info

, you must tie product identifiers (strings) to each item you are selling, using a specified format. Some stores require that you customize the Product ID for their stores.

Planning:

  • Define your strategy to determinhe when/how users can buy things
  • Define your pricing strategy
  • Define the types of products (subscriber, consumable, non consumable)

    plugin folders and files in Assets/Plugins/UnityPurchasing from your project.

Common Unity IAP integration compiler errors

The following error messages may indicate that Unity IAP is disabled in the Unity Cloud Services window, or that Unity is disconnected from the Internet: * CS0246 * System.Reflection.ReflectionTypeLoadException * UnityPurchasing/Bin/Stores.dll * UnityEngine.Purchasing

To resolve these errors:

Reload the Services window by closing, then reopening it. Once reloaded, ensure that the Unity IAP service is enabled. If this doesn’t work, try disconnecting and reconnecting to the Internet, then sign back into Unity Services and re-enable Unity IAP.

Note: You must have an Owner or Manager role for the project.
