[IOS] Subscribing promoted/introductory subscription

Version of react-native-iap :

4.5.2

Version of react-native :

ejected expo SDK38 0.62.2

Platforms you faced the error :

IOS only

Expected behavior

As already mentioned by closed issue #978 , it is not clearly stated if it is possible or not and how one can activate promoted subscriptions offer (not product, but subscription based offer). Reference : https://developer.apple.com/app-store/subscriptions/#offer-types

_Note for Android : even if the topic is iOS here, for Android, it’s easy to setup on Play Store an intro offer (free trial period), it is well activated with iap without any additional configuration. 👍 _

Actual behavior

When I list subscriptions, I have in the record a discounts entry including an offer that matches the one I’ve setup in AppStoreConnect : here an annual subscription with 1 month of trial

[ { 
    productId: 'com.XXX.sdk38.annual',
    subscriptionPeriodUnitIOS: 'YEAR',
    description: 'Activate Premium features on XXX',
    introductoryPrice: '',
    title: 'Annual',
    introductoryPriceSubscriptionPeriodIOS: '',
    introductoryPriceNumberOfPeriodsIOS: '',
    discounts: 
     [ { localizedPrice: '€0,00',
         numberOfPeriods: '1',
         type: 'SUBSCRIPTION',
         identifier: 'com.XXX.sdk38.tryannual',
         paymentMode: 'FREETRIAL',
         price: '0',
         subscriptionPeriod: 'MONTH' } ],
    type: 'Do not use this. It returned sub only before',
    localizedPrice: '€54,99',
    introductoryPricePaymentModeIOS: '',
    price: '54.99',
    currency: 'EUR',
    subscriptionPeriodNumberIOS: '1'
 }

If I try to activate the subscription with “com.XXX.sdk38.tryannual”, it tells me that productID does not exists. If I activate with “com.XXX.sdk38.annual”, it buys the subscription but without the trial period. If I setup an introductory offer and activate with “com.XXX.sdk38.annual”, it buys the subscription with the trial period.

Tested environment :

Real device iPhone 6S 13.x, sandbox account

Steps to reproduce the behavior

Ouch ! Maybe it just need a documentation update or clarification 😉

I was having the same issue and for the “withOffer” object you need to get your signed from your backend.

first, you need to follow this steps to get your key and privatekey https://help.apple.com/app-store-connect/#/dev689c93225

and when you get this values, you need to follow this tutorial, is an example with nodejs at the backend

cheers.
