[spare gyro]

Hi, i am trying to do stripe subscption through android pos nfc. my code for single payment is working fine. but when i triy this code which is for subscription then it is failing on frontend side even before showing paymentIntent. i would like to know what is wrong with my backend code

[azure zenith]

[spare gyro]

this if (!paymentSuccess || confirmedPI == null) {
result.error("PAYMENT_FAILED", "PaymentIntent failed or canceled", null)
return@collectAndConfirmPaymentIntent
}

hi there, taking over for my colleague who had to step away. do you have an ID for the failed Payment Intent? it should look like pi_2134

thanks! it looks like something in your code is cancelling the Payment Intent almost immediately after it's created https://dashboard.stripe.com/acct_1EW3fkJinHQ71v5x/test/logs/req_ENcALnwUswsMvU

ok, u would like to know which part is missing on backend side, we changed our code after this https://github.com/stripe/stripe-terminal-android/issues/651

here we are creating a paymentIntent

[tall tusk]

got it, so you're following this guide? https://docs.stripe.com/terminal/features/saving-payment-details/save-after-payment?terminal-sdk-platform=android

[spare gyro]

yes

[tall tusk]

can you share the part of your code where you're calling collectPaymentMethod()?

private fun processPayment(
clientSecretPI: String?,
result: MethodChannel.Result
) {
val terminal = Terminal.getInstance()
val reader = terminal.connectedReader

    if (reader == null) {
        result.error("NO_READER", "No connected reader available", null)
        return
    }
    
    if (clientSecretPI.isNullOrEmpty()) {
        result.error("MISSING_ARGS", "clientSecretPI is required", null)
        return
    }

    // Step 1️⃣: Process the initial one-time payment
    terminal.retrievePaymentIntent(clientSecretPI, object : PaymentIntentCallback {
        override fun onSuccess(paymentIntent: PaymentIntent) {
            collectAndConfirmPaymentIntent(terminal, paymentIntent) { paymentSuccess, confirmedPI ->
                if (!paymentSuccess || confirmedPI == null) {
                    result.error("PAYMENT_FAILED", "PaymentIntent failed or canceled", null)
                    return@collectAndConfirmPaymentIntent
                }

                // ✅ One-time payment only (no SetupIntent)
                val reply = mapOf(
                    "status" to "Payment Successful",
                    "transactionId" to confirmedPI.id
                )
                result.success(reply)
            }
        }

        override fun onFailure(e: TerminalException) {
            result.error("PAYMENT_INTENT_RETRIEVE_ERROR", e.message, null)
        }
    })
}

[tall tusk]

ok, can you confirm that terminal.retrievePaymentIntent() is retrieving the Payment Intent correctly? I would try adding logs to determine this
