Usage

Initialize the SDK

Android

val cardSessions = CardSessions.create(
    context = context,
    apiKey = "xnd_public_development_YOUR_KEY_HERE"
)

iOS

let cardSessions = CardSessionsFactory().create(
    apiKey: "xnd_public_development_YOUR_KEY_HERE"
)

Collect Card Data

Android

// Collect complete card information
val response = cardSessions.collectCardData(
    cardNumber = "4000000000001091",
    expiryMonth = "12",
    expiryYear = "2025",
    cvn = "123", // Optional
    cardholderFirstName = "John",
    cardholderLastName = "Doe",
    cardholderEmail = "[email protected]",
    cardholderPhoneNumber = "+1234567890",
    paymentSessionId = "ps-1234567890" // Session ID from your backend
)

iOS

// Using async/await
let response = try await cardSessions.collectCardData(
    cardNumber: "4000000000001091",
    expiryMonth: "12",
    expiryYear: "2025",
    cvn: "123", // Optional
    cardholderFirstName: "John",
    cardholderLastName: "Doe",
    cardholderEmail: "[email protected]",
    cardholderPhoneNumber: "+1234567890",
    paymentSessionId: "ps-1234567890"
)

Collect CVN Only

For saved cards where you only need to collect the CVN:

Android

val response = cardSessions.collectCvn(
    cvn = "123",
    paymentSessionId = "ps-1234567890"
)

iOS

let response = try await cardSessions.collectCvn(
    cvn: "123",
    paymentSessionId: "ps-1234567890"
)

Monitor Session State

Android

cardSessions.state.collect { state ->
    when {
        state.isLoading -> // Show loading state
        state.exception != null -> // Handle exception
        state.cardResponse != null -> // Handle success
    }
}

iOS

// Using Combine
cardSessions.state
    .sink { state in
        if state.isLoading {
            // Show loading state
        } else if let exception = state.exception {
            // Handle exception
        } else if let response = state.cardResponse {
            // Handle success
        }
    }

{
    "message": "Status updated. Wait for callback",
    "payment_token_id": "pt-1234567890",
