How to Let Shoppers Choose a Card Network (Co-Branded Cards)

val config = CardFormConfig(
    events = CardFormEvents(
        onPreferredSchemeChanged = { change ->
            // change.preferredScheme — selected canonical code (null when not co-branded)
            // change.cardSchemes    — all detected schemes, each with .selected
        }
    )
)
val cardForm = Payrails.createCardForm(config)

val config = CardFormConfig(
    translations = CardTranslations().apply {
        labels.cardBrandSelectorTitle = "Choose your network"
        labels.cardBrandSelectorSubtitle = "This card supports two networks"
    },
    styles = CardFormStylesConfig(
        cardBrandSelector = CardBrandSelectorStyle(
            selectedTileBorderColor = 0xFF0F63BD.toInt(),
            selectedCheckColor = 0xFF0F63BD.toInt(),
            tileCornerRadius = 12, // dp
        )
    ),
)

val result = session.binLookup("529741") // suspend; returns null on failure
if (result?.localNetwork != null) {
    // co-branded card: result.network + result.localNetwork
}
