Please follow steps below to setup iOS Native SDK and start accepting payment via PortOne.

Steps to integrate iOS SDK:#

  • Download the framework from here

  • After downloading the .xcframework, drag and drop it in the project

    • Go to General → Frameworks, Library and Embedded Content and then drop the framework and change the Embed to Embed & sign.

  • Import the PortOnePaymentSDK as below at the required places.

    import ChaiPayPaymentSDK

  • Initialize the checkout instance to get the available methods in SDK as below

    var checkout = Checkout(delegate: self, environment: "sandbox")

  • Set the environment as "dev" , "staging" to test in the required environments as below. While moving to the Production, set the environment to prod(default as prod).

    // value - dev, prod, staging
    checkout?.changeEnvironment(envType: "dev")
    //value - live,sandbox
    checkout?.changeEnvironmentMode(envType: "sandbox")

  • Should pass the delegate to the initialization

  • Should implement the delegate methods as below to get the response of failure and success callbacks from the webView.

    extension ViewController: CheckoutDelegate {
    func transactionResponse(transactionResponse: TransactionResponse?) {
    if let response = transactionResponse {
    // Do the needful with response
    }
    }
    //For webview to be open on top of the View controller
    var viewController: UIViewController? {
    return self
    }
    func transactionErrorResponse(error: Error?) {
    print("Error",error)
    }
    }

  • In the info.plist add the new Array type node LSApplicationQueriesSchemes as below:

  • <key>LSApplicationQueriesSchemes</key>
    <array>
    <string>itms-appss</string>
    <string>momo</string>
    <string>zalopay</string>
    <string>chaipay</string>
    </array>

    10.png

  • Include the URLType in info.plist to redirect to your app(deep linking) as below

    <key>CFBundleURLTypes</key>
    <array>
    <dict>
    <key>CFBundleTypeRole</key>
    <string>Editor</string>
    <key>CFBundleURLName</key>
    <string>checkout</string>
    <key>CFBundleURLSchemes</key>
    <array>
    <string>portOne</string>
    </array>
    </dict>
    </array>

Handle the deep link#

  • In sceneDelegate, redirect the deep link url to checkout instance
    func scene(_ scene: UIScene, openURLContexts URLContexts: Set<UIOpenURLContext>) {
    if let url = URLContexts.first?.url, url.absoluteString.hasPrefix("chaiport:") {
    // call the handle url method from checkout instance
    AppDelegate.shared.checkout?.handleUrl(url: url)
    }
    }

Initiate payments in following ways#

  • Initiate with tokenization flow
    • new credit card Payment
    • saved credit card payment
  • Initiate payment with non tokenization flow
    • wallets, BNPL, net banking

Initiate the wallet Payment

  • Initialize the wallet payment with transactionRequest as below:

    func prepareConfig(type: PaymentMethod) -> TransactionRequest {
    let countryCode = UserDefaults.getCurrency.code
    let billingDetails = BillingDetails(billingName: "Test mark", billingEmail: "markweins@gmail.com", billingPhone: number ?? "+66900002001", billingAddress: getBillingadress())
    let shippingAddress = ShippingAddress(city: "abc", countryCode: "TH", locale: "en", line1: "address_1", line2: "address_2", postalCode: "400202", state: "Mah")
    let shippingDetails = ShippingDetails(shippingName: "xyz", shippingEmail: "xyz@gmail.com", shippingPhone: "1234567890", shippingAddress: shippingAddress)
    var orderDetails: [OrderDetails] = []
    for details in self.selectedProducts {
    let product = OrderDetails(id: details.id ?? "", name: details.title ?? "", price: details.price ?? 0, quantity: 1, imageUrl: details.imageName ?? "")
    orderDetails.append(product)
    totalAmount = totalAmount + (details.price ?? 0)
    }
    let merchantDetails = MerchantDetails(name: "Downy", logo: "https://upload.wikimedia.org/wikipedia/commons/a/a6/Logo_NIKE.svg", backUrl: "https://demo.chaiport.io/checkout.html", promoCode: "Downy350", promoDiscount: 35000, shippingCharges: 0.0)
    print("UserDefaults.getTransactionType.code",UserDefaults.getTransactionType.code)
    var transactionRequest = TransactionRequest(portOneKey: chaipayKey , key: chaipayKey , merchantDetails: merchantDetails, paymentChannel: selectedPaymentMethod?.paymentChannelKey ?? "", paymentMethod: selectedPaymentMethod?.paymentChannelKey == "VNPAY" ? "VNPAY_ALL" : selectedPaymentMethod?.paymentMethodKey ?? "", merchantOrderId: "MERCHANT\(Int(Date().timeIntervalSince1970 * 1000))", amount: Int(self.totalAmount), currency: countryCode, signatureHash: "123", billingAddress: billingDetails, shippingAddress: shippingDetails, orderDetails: orderDetails, successURL: "https://test-checkout.chaiport.io/success.html", failureURL: "https://test-checkout.chaiport.io/failure.html", redirectURL: "chaiport://checkout", countryCode: countryCode, routingEnabled: false, routingParams: nil, transactionType: UserDefaults.getTransactionType.code)
    let signatureHash = createSignatureHash(transactionRequest)
    transactionRequest.signatureHash = signatureHash
    return transactionRequest
    }

  • Pass the TransactionRequest to initiateWalletPayments as below:

    // payload with proper payment channel and method
    let config = prepareConfig()
    checkOut?.initiatePayment(config) { result in
    switch result {
    case .success(let data):
    // Do nothing
    case .failure(let error):
    // Handle the error part
    print("error", error)
    break
    }
    }

    Handle the success and failure cases from the delegate method as below:

    extension ViewController: CheckoutDelegate {
    func transactionResponse(_ transactionResponse: TransactionResponse?) {
    if let response = transactionResponse {
    //Todo: Populate date or do the needful
    }
    }
    }

Steps for Signature Hash Generation#

  • Sample creation of signature hash. Follow the steps from the above link for more understanding

    // To generate Signature Hash
    func createSignatureHash(_ config: TransactionRequest) -> String {
    var message = ""
    message =
    "amount=\(config.amount)" +
    "&client_key=\(config.portOneKey.addingPercentEncoding(withAllowedCharacters: .urlHostAllowed) ?? "")" +
    "&currency=\(config.currency!.addingPercentEncoding(withAllowedCharacters: .urlHostAllowed) ?? "")" +
    "&failure_url=\(config.failureURL!.addingPercentEncoding(withAllowedCharacters: .urlHostAllowed) ?? "")" +
    "&merchant_order_id=\(config.merchantOrderId.addingPercentEncoding(withAllowedCharacters: .urlHostAllowed) ?? "")" +
    "&success_url=\(config.successURL!.addingPercentEncoding(withAllowedCharacters: .urlHostAllowed) ?? "")"
    let secretString = secretKey
    let key = SymmetricKey(data: secretString.data(using: .utf8)!)
    let signature = HMAC<SHA256>.authenticationCode(for: message.data(using: .utf8)!, using: key)
    let base64 = Data(signature).toBase64String()
    return base64
    }

Steps for generating JWT Token Generation#

  • Sample creation of JWT token. Follow the steps from the above link for more understanding

    // To generate createJWTToken
    func createJWTToken() -> String {
    struct Header: Encodable {
    let alg = "HS256"
    let typ = "JWT"
    }
    func generateCurrentTimeStamp (extraTime: Int = 0) -> Int {
    let currentTimeStamp = Date().timeIntervalSince1970 + TimeInterval(extraTime)
    let token = String(currentTimeStamp)
    return Int(currentTimeStamp)
    }
    let payload = Payload(iss: "CHAIPAY", sub: UserDefaults.getChaipayKey! ?? "", iat: generateCurrentTimeStamp(), exp: generateCurrentTimeStamp(extraTime: 1000000))
    print("UserDefaults.getChaipayKey",UserDefaults.getChaipayKey)
    let secret = UserDefaults.getSecretKey!
    let privateKey = SymmetricKey(data: secret.data(using: .utf8)!)
    let headerJSONData = try! JSONEncoder().encode(Header())
    let headerBase64String = headerJSONData.urlSafeBase64EncodedString()
    let payloadJSONData = try! JSONEncoder().encode(payload)
    let payloadBase64String = payloadJSONData.urlSafeBase64EncodedString()
    let toSign = (headerBase64String + "." + payloadBase64String).data(using: .utf8)!
    let signature = HMAC<SHA256>.authenticationCode(for: toSign, using: privateKey)
    let signatureBase64String = Data(signature).urlSafeBase64EncodedString()
    let token = [headerBase64String, payloadBase64String, signatureBase64String].joined(separator: ".")
    return token
    }
