Expired API Key provided: pss_live_YW*********************************************************************_******OvgX

Summary

SDK returning this TerminalException:
Expired API Key provided: pss_live_YW*********************************************************************_******OvgX

when calling Terminal.getInstance().retrievePaymentIntent(String, PaymentIntentCallback).

Code to reproduce

Connection token provider:

override fun fetchConnectionToken(callback: ConnectionTokenCallback) {
    GlobalScope.launch(Dispatchers.IO) {
        runCatching {
            cardReaderApi.requestStripeToken()
        }.onSuccess {
            it.response.data?.secret?.let { safeSecret ->
                callback.onSuccess(safeSecret)
            }
        }.onFailure { e ->
            callback.onFailure(
                ConnectionTokenException("Failed to fetch Stripe connection token", e),
            )
        }
        cancel()
    }
}

Code that returns the error:

Terminal.getInstance().retrievePaymentIntent(
    paymentIntentSecretToken.clientSecret // Fresh secret returned from the backend,
    object : PaymentIntentCallback {
           override fun onSuccess(paymentIntent: PaymentIntent) {
                  collectPaymentMethod(donationData, paymentIntent, readerPaymentApi)
           }

           override fun onFailure(e: TerminalException) {
                  // Here, the sdk returns the "Expired API Key provided" error.
                  sendGenericError(donationData, e)
                  readerPaymentApi.onPaymentFailed(e)
           }
    },
)

Android version

Android 13

Impacted devices (Android devices or readers)

I'm having the problem with the Stripe BBPOS WisePad 3, but I'm not sure if it's a card reader-related thing.

SDK version

com.stripe:stripeterminal:3.10.0

Other information

I'm not sure how to replicate this issue. It has happened in production to many users, and the only way to get rid of it is restarting the app (we connect the reader when the app starts and use the same reader connection over the entire app lifecycle)

@pvenrod are you able to provide a payment intent ID and let us know how frequently this issue is occurring?

[pvenrod]

I don't have the payment intent ID because the SDK fails exactly while retrieving it.

The issue is happening between 2-10 times per day, to different users. But this information is not realiable because it depends on how many payments tries the user to do, since when the issue starts to happen, it happens until the app is restarted, so if the user is having this error and tries to do 100 payments in a row (for example) without restarting the app, those 100 payments will fail with the same error explanation.

Is there anything else I can contribute/help?

Thank you!

Hi @pvenrod, I could not reproduce this error you're seeing; the SDK should attempt to auto-recover from session token expiry from retrievePaymentIntents, if you could please provide us with an example PaymentIntent or reader serial, we can troubleshoot further.
