Payments with myPOS iOS SDK

This guide explains how to accept payments and process refunds in your iOS app using the myPOS SDK. Follow the steps below for a smooth payment experience.

Make a Payment

To initiate a payment, create an instance of PaymentViewController with:

  • A list of CartItem objects
  • A unique Order ID
  • A Delegate to handle the result
let controller = PaymentViewController(cartItems: selectedCartItems, 
                                       orderId: ICUtils.randomOrderId, 
                                       delegate: self)
self.present(controller, animated: true, completion: nil)

Implement the PaymentDelegate

Make sure your class implements these methods:

func didMakePayment(transactionRef: String)
func paymentFailed(error: MobilePaymentSDKError)

Refund a Payment

Refunds require:

  • The Transaction Reference
  • The Order ID used for the payment
  • The Amount you want to refund

Also, provide:

  • A completed block (on success)
  • A failed block (on error)
MobilePaymentSDK.refundTransaction(transaction.reference, 
                                   orderId: transaction.orderId, 
                                   amount: amount, 
                                   completed: { (transactionRef) in
                                    showAlertWithText("Refund completed successfully")
}, 
                                   failed: { (error) in 
                             showAlertWithText("Refund failed. Error: \(error.message)")
})

Important:
Always make sure you are using the correct Transaction Reference ID for the refund
