How to Accept Redirect Payments

val configuration = Configuration(
    initData = InitData(version = payload.version, data = payload.data),
    option = Options()
)
val session = Payrails.createSession(configuration)

val redirectMethods: List<PayrailsPaymentOption> =
    session.getPaymentMethodConfig(PaymentMethodFilter.Redirect)

redirectMethods.forEach { method ->
    val button = Payrails.createGenericRedirectButton(
        translations = CardPaymenButtonTranslations(
            label = method.displayName ?: method.paymentMethodCode
        ),
        paymentMethodCode = method.paymentMethodCode
    )

    button.delegate = object : GenericRedirectPaymentButtonDelegate {
        override fun onPaymentButtonClicked(button: GenericRedirectButton) {
            // Payment flow started — show loading indicator if desired
        }

        override fun onAuthorizeSuccess(button: GenericRedirectButton) {
            // Payment succeeded — navigate to success screen
        }

        override fun onAuthorizeFailed(button: GenericRedirectButton) {
            // Payment failed — show error UI
        }

        override fun onPaymentSessionExpired(button: GenericRedirectButton) {
            // Session expired during redirect — prompt user to retry
        }

        override fun onStateChanged(button: GenericRedirectButton, state: ButtonState) {
            // LOADING when payment starts, ENABLED when it completes
        }
    }

    // In Compose
    button.Render(modifier = Modifier.padding(horizontal = 24.dp))
}

val configuration = Configuration(
    initData = initData,
    option = Options(
        redirectSessionLifecycle = RedirectSessionLifecycle(
            onSessionExpired = {
                val refreshed = fetchInitPayloadFromBackend()
                InitData(version = refreshed.version, data = refreshed.data)
            }
        )
    )
