Usage

First you need to create a merchant account on our platform

Before you can start the payment flow you need to tokenize the card number and the CVC code of the given card you are trying to charge.

Example of tokenization:

import PaylikeClient

let client = PaylikeClient()

/**
    COMPLETION HANDLER BASED USAGE
    ------------------
*/
client.tokenize(type: PaylikeTokenizedTypes.PCN, value: "4100000000000000") { result in
    // Save tokenized card number...
}

/**
    ASYNC USAGE
    ------------------
*/
Task {
    let response = try await client.tokenize(type: PaylikeTokenizedTypes.PCN, value: "4100000000000000")
}

/**
    SYNC USAGE
    ----------
*/
client.tokenizeSync(type: PaylikeTokenizedTypes.PCSC, value: "123") { result in 
    // Save tokenized card security code...
}

After the tokenization is done, you can now start the payment flow. You need to collect 12 hints (assuming that TDS is enabled) before your payment is considered finished and committed. paymentCreate function is constructed to work in a recursive way automatically resolving challenges as much as possible.

For more information on the flow please check our API reference.

Example:

import PaylikeClient

// Previously got tokenized data:
let (numberToken, cvcToken) = ("RESULT_OF_TOKENIZE", "RESULT_OF_TOKENIZE")

let integrationKey = PaymentIntegration(merchantId: key)
let paymentAmount = PaymentAmount(currency: .EUR, value: 1, exponent: 0)
let expiry = try CardExpiry(month: 12, year: 26)
let card = PaymentCard(number: numberToken, code: cvcToken, expiry: expiry)
var createPaymentRequest = CreatePaymentRequest(with: card, merchantID: integrationKey)
createPaymentRequest.amount = paymentAmount

/**
    COMPLETION HANDLER BASED USAGE
    ------------------
*/
client.createPayment(with: createPaymentRequest) { result in
    // handle payment flow completion
}

/**
    ASYNC USAGE
    ----------
*/
Task {
    let clientResponse = try await client.createPayment(with: createPaymentRequest)
}

/**
    SYNC USAGE
    ----------
*/
client.createPaymentSync(with: createPaymentRequest) { result in
    // handle payment flow completion
}
