Want to add discount offer to the subscriptions with requestSubscription

[MaximeDemurger]

Hi Everyone,

I'm running into an issue. I want to apply a discount offer to a subscription for specific type of user.
To get all the sku I use the getSubscriptions(['sku', 'sku2']) function which return me all the valid subscriptions.

Here is an example :
[{"countryCode": "USA", "currency": "USD", "description": "", "discounts": [{"identifier": "promo8", "localizedPrice": "26.49 $", "numberOfPeriods": "1", "paymentMode": "PAYASYOUGO", "price": "26.49", "subscriptionPeriod": "MONTH", "type": "SUBSCRIPTION"}], "introductoryPrice": "", "introductoryPriceAsAmountIOS": "", "introductoryPriceNumberOfPeriodsIOS": "", "introductoryPricePaymentModeIOS": "", "introductoryPriceSubscriptionPeriodIOS": "", "localizedPrice": "44.99 $", "platform": "ios", "price": "44.99", "productId": "com.example.app.price8", "subscriptionPeriodNumberIOS": "6", "subscriptionPeriodUnitIOS": "MONTH", "title": "", "type": "subs"}]

Now to create a subscriptions to the user I use the requestSubscriptions() function

purchase = await requestSubscription({ sku: currentSelect?.id_product, withOffer: { identifier: currentSelect?.id_promo, keyIdentifier: '.............', signature: '..............', timestamp: Date.now(), }, });
This is how I use it. And when I try to call it, it doesn't apply the discount offer.
What can I do ? How can I apply the reduction ? What are corresponding keyIdentifier, nonce, and signature parameters to ?
Where can I find them ?

    Thanks.

Those should come from your server. Here is an explanation of the whole process: https://developer.apple.com/documentation/storekit/in-app_purchase/original_api_for_in-app_purchase/subscriptions_and_offers/implementing_promotional_offers_in_your_app
