[IOS] Expiration of paid subscription and owned attribute of IAPProduct

[ebeling]

I develop InApp - purchase in an ionic app. For testing under ios I use sandbox and sandbox user as you described. My product is a paid subscription. For server side receipt validation I use your server (https://billing.fovea.cc). I can see at your web interface under Customer that a subscription is expired - the Expiry Date is red. In my application an expired-event is triggered. While the attribute 'isExpired' is 'true' (I can see this in Safari Developer Console) the value of the attribute 'owned' is 'true'. On your [API documentation] (https://github.com/j3k0/cordova-plugin-purchase/blob/master/doc/api.md) you say under the title Subscription: "If the validator returns a store.PURCHASE_EXPIRED error code, the subscription will automatically loose its owned status." Why is the owned attribute not false, if subscription is expired? Is this a sandbox problem?

system info

Ionic CLI: 5.4.15 Cordova CLI: 9.0.0 cordova-ios: 5.1.1 @ionic-native/in-app-purchase-2: 5.21.5 cordova-plugin-purchase: 10.0.1

Device: iPhone 11, iOS 13.3.1

Expected behavior

product.owned = false (after expiration)

Observed behavior

product.owned = true

You know https://developer.apple.com/documentation/storekit/in-app_purchase/subscriptions_and_offers/handling_subscriptions_billing?changes=_8 ?

That maybe explain the problem that you see.

Thank you for your reply! I've read the article. I realized, that isBillingRetryPeriod = true in my example. But how can I ask for it with Ionic api, the IAPProduct - type does not have this attribute ? And when you set the owned-attribute to 'true'? Other question: can you tell me please, what does this icons on the "Receipt"-page means:

Good question, get the same. but playing with google and ionic.

• in app, purchase a subscription with fovea.cc validator

• with postman, send a request to validator.fovea.cc => "isExpired": false

• go on play.google.com and remove subscription

• with postman, resend => "isExpired": true

• store.refresh(), the product is still owned (state:owned)

The only way is to make a change in code with --livereload, and after app reload, product state become valid.

This is my first (french) days with IAP and it's heavy...

@ebeling : How do you setup to cordova-plugin-purchase: 10.0.1 ? when i follow in-app-purchase-2 i get "cc.fovea.cordova.purchase": "^8.1.1", So to add applicationUsername i have to follow application-username with version < 9

Ionic CLI: 5.4.5 Cordova CLI: 9.0.0 Cordova Platforms : android 8.1.0 "@ionic-native/in-app-purchase-2": "^5.22.0" "cc.fovea.cordova.purchase": "^8.1.1"

Best regards

@jfpwork You can get the new version of cordova-plugin-purchase with ionic cordova plugin add cordova-plugin-purchase@10.0.1

I found out, that 'owned' - attribute will be written only once: if 'owened' - event triggered it is set to "true". It will never be set back to "false". A reload is the same like a new app start: then the store is new initialized and therefore the 'owned' - attribute is false, if subscription is expired. I don't use the 'owned' - attribute now to decide if the payed function is available, I use the 'state' - attribute:

if (product.state === this.store.OWNED) { //TODO payed function available } else if (product.state === this.store.VALID) { // TODO payed function not available }

And I call 'this.store.refresh()' every time, the user wants to use the payed function. I don't know if this is the correct way for auto renewable subscriptions.

@ebeling thanks, i strike out by following a similar way. Now the question is how to check and when to check the product state throw ngrx... I will test this point of view; this is outside the topic but welcome if you want to discuss about it. Take care

[ebeling]

@jfpwork Thanks for your link. it's very interesting. I detected another problem in praxis test: what to do, if there are no internet connection while testing subscription state and products can't be loaded from store. Is it necessary to store product information local?

[jfpwork]

My response is maintain a info about your customer/purchase and keep your app up to date with your server which is up to date with google

Hey, what's the status of your issue?

[ebeling]

The question is open: Why is the owned attribute not false, if subscription is expired?

[steveetm]

Having the very same issue. I made a sandbox purchase, it is now expired is but owned is true. What is worse that the plugin tries to verify it every minute with the server.

expiryDate: Mon Mar 30 2020 12:16:56 GMT+0200 (CEST)
isBillingRetryPeriod: false
isExpired: true
isIntroPeriod: false
isTrialPeriod: false
lastRenewalDate: Mon Mar 30 2020 12:11:56 GMT+0200 (CEST)
loaded: true
owned: true
purchaseDate: Mon Mar 30 2020 12:11:02 GMT+0200 (CEST)
renewalIntent: "Lapse"
state: "valid"

[j3k0]

The server does give a few minutes of grace period to the user (sometime renewal events take some time to arrive). If you don't want to apply a grace period, you can use the condition owned && !expired.
