Before initializing the transfer page, you need to install the SDK in your mobile application.

Instructions for launching the translation page in the SDK

After configuring the SDK in your mobile application, proceed to setting up the translation itself.

You have the option to launch several types of translation:

Example of initializing an Invoice instance in iOS

import EpaySDK

let invoice = Invoice(
    id: invoiceId,
    amount: amount,
    currency: "KZT",
    accountId: "1",
    description: "",
    postLink: "https://testmerchant/order/1123",
    failurePostLink: "https://testmerchant/order/1123/fail",
    isRecurrent: false,
    autoPaymentFrequency: .weekly,
    transferType: .P2P
)

// Transfer Types
public enum TransferType: String, CaseIterable {
  case P2P, AFT, OCT, CardId, byPhone}

Example of initializing an Invoice instance in Android

import com.ss.halykepay.data.model.Invoice

val invoice = Invoice(
    id = invoiceId,
    amount = amount,
    currency = "KZT",
    accountID = "1",
    description = "",
    postLink = "https://testmerchant/order/1123",

)

2. Launching payment page

iOS Example

import EpaySDK

let pm = PaymentModel(authConfig: <Previously configured AuthConfig>, invoice: <Invoice instance created by paragraph above>)

let launchScreenVC = LaunchScreenViewController(paymentModel: pm)
launchScreenVC.setEnvironmetType(type: .prod) //for the test, use .dev
navigationController?.pushViewController(launchScreenVC, animated: true)

Android Example

Using the previously created instance of HalykEpaySDK, launch the payment page by passing the instance of Invoice.
halykEpaySdk.launchEpay(invoice)
