Flutter Apple pay error production_simulator

[adia]

I was working to integrate Apply pay. It loads just fine but when I try to process the payment it fails.

I generated a CSR using the sandbox Apple Pay and loaded it correctly to the Apple developer program Merchant ID. I confirmed I'm using my sandbox application ID. All other transactions go through for me (credit cards and Google pay) to the sandbox. Just not working for apply pay.

Hey @adia,

I reached out to our API team on this one and they said as far as they know- you do not need to load a sandbox apple pay CSR - it should just be a regular production CSR on Apple Pay’s developer portal, and as long as you use Square's sandbox application ID, it won’t be charged.

I created a CSR from square for both sandbox and production both give me the same error in my initial question. I'm using the flutter Square In-app SDK. Maybe I need to post the issue on their public GitHub project?

These are the steps for Apply pay. Using google pay and Credit cards work fine.  

await InAppPayments.setSquareApplicationId(SANDBOX_APPLICATION_ID);

await InAppPayments.initializeApplePay(MERCHANT_ID);

await InAppPayments.requestApplePayNonce(
    price: '1.00',
    summaryLabel: 'Cookie',
    countryCode: 'US',
    currencyCode: 'USD',
    paymentType: ApplePayPaymentType.finalPayment,
    onApplePayNonceRequestSuccess: _onApplePayNonceRequestSuccess,
    onApplePayNonceRequestFailure: _onApplePayNonceRequestFailure,
    onApplePayComplete: _onApplePayEntryComplete);
