preferredScheme

abstract suspend fun preferredScheme(response: POCardTokenizationPreferredSchemeResponse)

Allows to provide a preferred scheme that will be used for card tokenization by default. Response must be constructed from request that has been collected by subscribing to preferredSchemeRequest.

viewModelScope.launch {
    with(ProcessOut.instance.dispatchers.cardTokenization) {
        preferredSchemeRequest.collect { request ->
            // Inspect issuer information to choose a default preferred scheme.
            val preferredScheme = when (request.issuerInformation.scheme) {
                "visa", "mastercard" -> request.issuerInformation.coScheme
                else -> request.issuerInformation.scheme
            }
            // Send the response with preferred scheme which must be constructed from request.
            // Note that once you've subscribed to 'preferredSchemeRequest' it's required to send response back.
            // Implementation will use primary scheme if 'preferredScheme' is null.
            preferredScheme(request.toResponse(preferredScheme = preferredScheme))
        }
    }
