How to detect active subscription when visiting subscription page

[scattered]

I'm using cordova-plugin-purchase version 13.8.6 and fovea.cc within my Ionic application.

When a user navigates to the subscription page I want to put a green checkmark next to the active subscription to indicate that which subscription they have (1 month, 3 month or 12 month).

When the page loads I perform the following:

CdvPurchase.store.minTimeBetweenUpdates = 1000; // For testing purposes only
CdvPurchase.store.verbosity = CdvPurchase.LogLevel.DEBUG; // For testing purposes only

CdvPurchase.store.register([PRODUCTS ARRAY]);

CdvPurchase.store.error(err => { console.error(err) });
CdvPurchase.store.ready(()=> {
  CdvPurchase.store.update().then(() => {
    console.log(CdvPurchase.store.verifiedPurchases) // Always an empty array
    console.log(CdvPurchase.store.owned('sub_1_month')) // Always false
    console.log(CdvPurchase.store.owned('sub_3_month')) // Always false
    console.log(CdvPurchase.store.owned('sub_12_month')) // Always false
  });
});

CdvPurchase.store.when().receiptUpdated(receipt  => { receipt.verify() });
CdvPurchase.store.when().productUpdated(product  => {
  console.log(product.owned) // Always false
});
CdvPurchase.store.when().approved(transaction  => { transaction.verify() });
CdvPurchase.store.when().verified(receipt  => { receipt.finish() });
CdvPurchase.store.when().finished(transaction  => {
  // Update UI after purchase
});

CdvPurchase.store.initialize();

As you can see form the above, calling owned is always false and verifiedPurchases is always an empty array.

How can I detect if a subscription is active?

Note: I can see the webhooks being executed in the fovea.cc dashboard and being received and processed on my server. I can also detect if the user has an active subscription on the server by looking at the data I save from the fovea.cc webhook which includes the UTC expiry date. However, I would assume that I can retrieve the information from within the plugin so I don't need to do another server request.

Note: I'm using sandbox accounts to test the purchases

Note: I'm testing on real iOS and Android devices.

Note that it is incorrect to call "update()" after the "ready()" event.

• "ready" is triggered after initialization.
• initialization process includes the operations done by "update()", so it's redundant.

CdvPurchase.store.ready(()=> {
  CdvPurchase.store.update().then(() => {
    console.log(CdvPurchase.store.verifiedPurchases) // Always an empty array
    console.log(CdvPurchase.store.owned('sub_1_month')) // Always false
    console.log(CdvPurchase.store.owned('sub_3_month')) // Always false
    console.log(CdvPurchase.store.owned('sub_12_month')) // Always false
  });
});

The below is also incorrect:

CdvPurchase.store.when().receiptUpdated(receipt  => { receipt.verify() });

You should only verify approved transactions.

---

CdvPurchase.store.when().productUpdated(product  => {
  console.log(product.owned) // Always false
});

"productUpdated" is ony called when the product's metadata are updated (pricing, title, ...)

So you won't get a call to productUpdated after receipt validation. The right place to check for ownership, when using a receipt validation service, is generally the "verified()" and "unverified()" handlers.

I advise you switch from fovea.cc to https://iaptic.com -- just replace "fovea.cc" by "iaptic.com" in the validator URL and it will work right away: cf https://www.iaptic.com/documentation/information-fovea-billing

I also advise you check the example for an example implementation of subscription: https://github.com/j3k0/cordova-subscription-example -- the "with-server" example will apply to your case.

I have the same problem product.owned is always false. Test on IOS. I switched from version 11 to 13. The validation runs via my own server. There were no problems. I have tried to stick to the "with-server" example. Which call could still be missing to set product.owned?

My validation response json:

{ ok: true, status: 'valid', data: { product_id: purchase.productId, quantity: 1, transaction_id: purchase.transactionId, purchase_date: purchase.purchaseDate, expiration_date: purchase.expiresDate || purchase.expirationDate, "is_canceled": false, "is_refunded": false, id: purchase.productId, latest_receipt: true, transaction: _transaction } }

The subscription is active in the device. (Store subscription overview) Even after I restarted the app, "owned" is still false.

Make sure the collection field is filled by the receipt validator. This is how "owned" products are sent by the server to the plugin.
