## README - In-App Purchasing Sample Scenes - Apple App Store - Upgrading and Downgrading Subscriptions
|
||
|
|
|
||
|
|
This sample showcases how to use Unity IAP to upgrade and downgrade subscriptions. This allows
|
||
|
|
players to change their subscription, and pay a different amount of money for a different level of service.
|
||
|
|
|
||
|
|
You can offer users different subscription tiers, such as a base tier and a premium tier or monthly and yearly
|
||
|
|
subscriptions. A user that is already subscribed may be given the opportunity to pay a different amount of money to upgrade or
|
||
|
|
downgrade their subscription's tier to a different service level.
|
||
|
|
|
||
|
|
On Apple, the user purchases a subscription, and upgrades or downgrades by purchasing a second, or by visiting the [Manage Subscriptions](https://support.apple.com/en-us/HT204939) sheet.
|
||
|
|
|
||
|
|
## Instructions to test this sample:
|
||
|
|
|
||
|
|
1. Have in-app purchasing correctly configured with
|
||
|
|
the [Apple App Store](https://docs.unity3d.com/Packages/com.unity.purchasing@3.2/manual/UnityIAPAppleConfiguration.html).
|
||
|
|
2. Configure two subscriptions of different tiers in the Apple App Store, under the same subscription group. This can be as simple as having a "normal"
|
||
|
|
subscription and a "VIP" subscription. Assign both of these products to a single [Subscription Group](https://help.apple.com/app-store-connect/#/dev75708c031).
|
||
|
|
3. Set your own product's id in
|
||
|
|
the `InAppPurchasing game object > Upgrade Downgrade Subscription script > Normal Subscription Id field / Vip Subscription Id field`
|
||
|
|
or change the `normalSubscriptionId` and `vipSubscriptionId` fields in the `UpgradeDowngradeSubscription.cs` script.
|
||
|
|
4. Build your project for `iOS`.
|
||
|
|
|
||
|
|
NOTE: Testing may be complicated and not convincing when using the Apple Sandbox app store. Only certain dialogs may appear, and there may be no "upgrade / downgrade" UI presented. Also the "Manage Subscriptions" Apple iOS feature may not work when testing with the Sandbox.
