Masterpass iOS SDK

IOS integration

Portmone SDK supports iOS 8.0 version and above.

Opportunities provided by Portmone SDK

Masterpass wallet:

• add cards to an existing wallet or create a new one;
• delete cards from an existing wallet;
• get a list of cards for an existing wallet.

Payment:

• adding funds to a mobile phone account using Masterpass cards;
• paying for services by personal account using Masterpass cards.

Before getting started

Sign up at Masterpass™

To get started with Masterpass™, you need to go through the merchant registration process at developers.mastercard.com. To do this:

1. Go to https://developer.mastercard.com/account/sign-up
2. Complete the registration form and then go through the e-mail confirmation procedure
3. Create project on the page https://developer.mastercard.com/dashboard → Create new project

Sign up at Portmone.com

After receiving the keys from Masterpass™, send the following information to the Portmone.com:

• the keys data from your personal account, namely:

  • Public key (Press “Actions” → “Download *.pem”)
  • Keystore password
  • Key alias

You can find these data in the Key Management section at https://developer.mastercard.com/masterpass/merchant/#/keyManagement2

• Masterpass™ Checkout ID (copy from the next page in your personal account: https://developer.mastercard.com/masterpass/merchant/#/checkoutCredentials)

You should send the information via email at SDKpartners@portmone.me with the subject “Partner [Your company's name] Onboarding”. Please make sure that you have permanent access to the mailbox from which you will send this email and that the mailbox is registered with your company's trusted domain. Emails from free public domains (gmail.com, yahoo.com, ukr.net etc.) will be automatically filtered out.

After registering your Masterpass™ Merchant data in the Portmone.com system, you will be contacted to assist on further integration and testing steps and will be provided the following information:

• Portmone.com Merchant Id;
• Portmone.com Merchant Login;
• The current version of the SDK for the iOS and/or Android platforms along with the samples of applications that use SDK.

1. Get started with the SDK

To use the SDK methods, before you get started you need to call a method which accepts a set of required parameters to work with SDK:

PortmoneSDK(merchantKey, clientId)

Parameters

Field	Type	Description	Nullability
clientId	String	A unique identifier of the client in the Masterpass system.	required
merchantKey	String	Unique key.	required

2. Authorization (AuthorizationService)

To use SDK features you should log in to the system. AuthorizationService, which is publicly available, and its authorize method are used for authorization. Authorization for one user is stored during the life of the application after calling the method. To change the user you need to call this method again with other parameters.

During the method call, the wallet status is checked using the specified phone number. If necessary, the client is automatically linked to the Masterpass system. In this case, card verification with the OTP code is necessary and error 2113 appears.

AuthorizationService

public func authorize(phone: String,
                      userId: String,
                      completion: @escaping OperationCompletion)

authorize method parameters

Parameter	Type	Description	Example
phoneNumber	String	User mobile phone number. Used as an identifier in the Masterpass wallet.	“380666789555”
userId	String	User ID in the Portmone system. Required for identification in the Portmone system.	“3715100”
completion	OperationCompletion	Asynchronous callback with the result of authorization.

Getting authorization result:

OperationCompletion

public typealias OperationCompletion = (Bool, Error?) -> Void

OperationCompletion parameters

Parameters	Description
Bool	Authorization result: true - successful, false - unsuccessful.
Error?	Called when an error occurs during this operation. The parameter may be a system error or an Error object. When checking the status of a wallet, an error 2113 may occurs, which requires OTP verification of the card.

Example:

let service = AuthorizationService()
service.authorize(phone: "380666789555",
                  userId:"3714123") { [weak self] isSuccess, error in
            if error != nil {
                let code = (error as NSError?)?.code
                switch code {
                case 2113?:
                    self?.performSegue(withIdentifier: self?.confirmCardSegue ?? "", 
sender: self)

                default:
                    self?.presentAlert(title: "Error \(code ?? 0)",
                                       message: error?.localizedDescription)
                }
            } else {
                self?.presentAlert(title: "Success",
                                   message: "Authorization success.") { _ in
                    self?.performSegue(withIdentifier: "Functionality", sender: nil)
                }
            }
        }
