Deferred Purchases

Deferred and pending purchases

Deferred or interrupted in-app purchases may happen when SCA confirmation is needed, in the case of parental control and some other cases.
Here is what the deferred purchase flow looks like:

a user initiates a purchase
purchase is received in state deferred.
you receive a purchase result with a pending purchase status (on iOS and Android) or an error with a deferred purchase description (on cross-platform SDKs)

Qonversion.shared().purchase(product) { (result) in
  if result.isPending {
    // Handle pending purchase
  }
}

[[Qonversion sharedInstance] purchaseWithResult:product completion:^(QONPurchaseResult * _Nonnull result) {
  if (result.isPending) {
    // Handle pending purchase
  }
}];

Qonversion.getSharedInstance().purchase(this, product, new QonversionPurchaseCallback() {
    @Override
    public void onResult(@NonNull QPurchaseResult result) {
        if (result.isPending()) {
            // Handle pending purchase
        }
    }
});

Qonversion.shared.purchase(this, product, object : QonversionPurchaseCallback {
    override fun onResult(result: QPurchaseResult) {
        if (result.isPending) {
            // Handle pending purchase
        }
    }
})

try {
  final Map<String, QEntitlement> entitlements = await Qonversion.getSharedInstance().purchaseProduct(product);
} on QPurchaseException catch (e) {
  if (e.code == QErrorCode.purchasePending) {
    // Purchase is pending
  }
  print(e);
}

try {
  const entitlements: Map<string, Entitlement> = await Qonversion.getSharedInstance().purchaseProduct(product);
} catch (e) {
  if (e.code === QonversionErrorCode.PURCHASE_PENDING) {
    // Purchase is pending 
  }
  console.log(e);
}

Qonversion.GetSharedInstance().PurchaseProduct(product, (entitlements, error, isCancelled) =>
{
  if (error == null)
  {
    if (entitlements.TryGetValue("premium", out Entitlement premium) && premium.IsActive)
    {
      // Handle the active entitlement here
    }
  }
  else
  {
    if (qonversionError.Code == QErrorCode.PurchasePending)
    {
      // Purchase is pending
    }
  }
});

try {
  const entitlements = await Qonversion.getSharedInstance().purchaseProduct(product);
} catch (e) {
  if (e.code === QonversionErrorCode.PURCHASE_PENDING) {
    // Purchase is pending 
  }
  console.log(e);
}

try {
  const entitlements: Map<string, Entitlement> = await Qonversion.getSharedInstance().purchaseProduct(product);
} catch (e) {
  if (e.code === QonversionErrorCode.PURCHASE_PENDING) {
    // Purchase is pending 
  }
  console.log(e);
}

if a transaction completes successfully later, Apple StoreKit or Google Billing Service returns a successful purchase
Qonversion SDK returns a successful purchase

Make sure your app handles deferred or interrupted transactions by setting a delegate and a function that is triggered when such a transaction is made.

🚧
Attention
Please note, this function is called only in case of deferred purchases. The purchase flow happens as described here for all other cases.

Provide entitlements update listener

Set the delegate to handle pending purchases and implement the corresponding function to handle new entitlements when the purchase is completed.

Qonversion.shared().setEntitlementsUpdateListener(self)

...

func didReceiveUpdatedEntitlements(_ entitlements: [String : Qonversion.Entitlement]) {
    // handle updated entitlements here
}

[[Qonversion sharedInstance] setEntitlementsUpdateListener:self];

...

- (void)didReceiveUpdatedEntitlements:(NSDictionary<NSString *, QONEntitlement *>  * _Nonnull)entitlements {
    // handle updated entitlements here
}

Qonversion.getSharedInstance().setEntitlementsUpdateListener(entitlements -> {
    // handle updated entitlements here
});

Qonversion.shared.setEntitlementsUpdateListener(object : QEntitlementsUpdateListener {
    override fun onEntitlementsUpdated(entitlements: Map<String, QEntitlement>) {
        // handle updated entitlements here
    }
})

StreamSubscription<Map<String, QEntitlement>> _updatedEntitlementsStream;
_updatedEntitlementsStream = Qonversion.getSharedInstance().updatedEntitlementsStream.listen((entitlements) => {
   // handle updated entitlements here
});

Qonversion.getSharedInstance().setEntitlementsUpdateListener({
    onEntitlementsUpdated(entitlements) {
        // handle updated entitlements here
    },
});

Qonversion.GetSharedInstance().UpdatedEntitlementsReceived += HandleUpdatedEntitlements;

private void HandleUpdatedEntitlements(Dictionary<string, Entitlement> entitlements)
{
    // handle updated entitlements here
}

Qonversion.getSharedInstance().setEntitlementsUpdateListener({
    onEntitlementsUpdated(entitlements) {
        // handle updated entitlements here
    },
});

Qonversion.getSharedInstance().setEntitlementsUpdateListener({
    onEntitlementsUpdated(entitlements) {
        // handle updated entitlements here
    },
});

You can also provide a listener during the initialization for some platforms as follows:

final QonversionConfig qonversionConfig = new QonversionConfig.Builder(
        this,
        "projectKey",
        QLaunchMode.SubscriptionManagement
)
        .setEntitlementsUpdateListener(entitlements -> {
            // handle updated entitlements here
        })
        .build();
Qonversion.initialize(qonversionConfig);

val qonversionConfig = QonversionConfig.Builder(
    this,
    "projectKey",
    QLaunchMode.SubscriptionManagement
)
    .setEntitlementsUpdateListener(object : QEntitlementsUpdateListener {
        override fun onEntitlementsUpdated(entitlements: Map<String, QEntitlement>) {
            // handle updated entitlements here
        }
    })
    .build()
Qonversion.initialize(qonversionConfig)

const config = new QonversionConfigBuilder(
  'projectKey',
  LaunchMode.SUBSCRIPTION_MANAGEMENT
)
  .setEntitlementsUpdateListener({
      onEntitlementsUpdated(entitlements) {
          // handle updated entitlements here
      },
  })
  .build();
Qonversion.initialize(config);

const config = new Qonversion.ConfigBuilder(
  'projectKey',
  Qonversion.LaunchMode.SUBSCRIPTION_MANAGEMENT
)
  .setEntitlementsUpdateListener({
      onEntitlementsUpdated(entitlements) {
          // handle updated entitlements here
      },
  })
  .build();
Qonversion.initialize(config);

const config = new QonversionConfigBuilder(
  'projectKey',
  LaunchMode.SUBSCRIPTION_MANAGEMENT
)
  .setEntitlementsUpdateListener({
      onEntitlementsUpdated(entitlements) {
          // handle updated entitlements here
      },
  })
  .build();
Qonversion.initialize(config);
