Getting Started

Follow the instructions below to get started with VelaOffline iOS SDK



CocoaPod is a dependency manager for Cocoa projects. For usage and installation instructions, visit their website. To integrate VelaSDK into your Xcode project using CocoaPods, specify it in your Podfile:

pod 'VelaSDK', '~> 1.0'


For this step, you will need to set your SMS Sort Code, Shared Service Code and SMS Encryption Key for the Vela Control System. To Setup, Initialize the SDK as shown below:

  1. Extend the VelaAPI class, and override smsAPIShortCode(bool: isLive), smsEncryptionKey(), merchantSharedCode functions to set the SMS Sort Code, Encryption Key, and Shared Service Code respectively. e.g.

    class MyAPI: VelaAPI{
        override func smsAPIShortCode(bool: isLive) -> String{
            return isLive ? "33445" : "12345"
        override func smsEncryptionKey() -> String{
            return "enkey0123456789"
        override func merchantSharedCode() -> String? {
            return "05" 
  2. In your AppDelegate application func, i.e func application, call the initVela(api: VelaAPI, isLive: Bool) method with the extended VelaAPI as the api argument. e.g
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        initVela(api: MyAPI(), isLive: false)


To send SMS API Request from a UIViewController, you must first extend the SMSUIViewController class, and then call the sendRequest(encryptedMessage: String) or sendRequest(message: SMSMessagePipeline) method. e.g.

class MainUIViewController: SMSUIViewController{
    override func viewDidLoad() {
            let message = ... 
            sendRequest(encryptedText: message)

    //called after an SMS request is sent
    open func smsRequestSent(controller: MFMessageComposeViewController, result: MessageComposeResult){
        controller.dismiss(animated: true, completion: nil)

Creating a Transaction SMS Request

To create a transaction request, e.g Cash Transfer request, firstly, you have declare CashTransferSMSAPI class and then pass the neccessary payload data.

let data = CashTransferSMSAPI.Data()
data.accountNo = "1234567890"
data.amount = 10000 = Bank.UBA_BANK = "xxxx"
data.sourceBankAccountId = "123456"
data.userId = "12345678"

let cashTransferSMSApi = CashTransferSMSAPI(data: data)
sendRequest(message: cashTransferSMSApi)

once a request is sent, an SMS response message containing a 6-digits comfirmation code is sent back to the user, the user is required to input the confirmation code on the app, which is then validated to perform a corresponding action.

Validating Confirmation code

let confirmationCode = ...

let validation = cashTransferSMSApi.validateConfirmationCode(confirmationCode: confirmationCode)
case ConfirmationMessageResult.REQUEST_SUCCESSFUL:
    // cash transfer request was successful:  
case ConfirmationMessageResult.REQUEST_FAILED:
    // cash transfer request failed
case ConfirmationMessageResult.OTP_REQUIRED:
    // otp is required required for cash transaction
    //an invalid confirmation code was inputed

Table of Transaction SMS API Classes:

Class Name Data Payload Class Description
AccountCreationSMSAPI AccountCreationSMSAPI.Data User Account Creation
AccountCreationConfirmationSMSAPI AccountCreationConfirmationSMSAPI.Data Stage 2 of Account Creation, Verifying Account Number and OTP
AccountLoginSMSAPI AccountLoginSMSAPI.Data User Login and Account Authentication.
UserProfileUpdateSMSAPI UserProfileUpdateSMSAPI.Data User Profile Information Update.
CashTransferSMSAPI CashTransferSMSAPI.Data Cash Transfer.
BillPaymentSMSAPI BillPaymentSMSAPI.Data Bill Payment such as Airtime, Data, Electricity, etc.
NewBankAccountSMSAPI NewBankAccountSMSAPI.Data Add a new Transaction Bank Account.
PinUpdateSMSAPI PinUpdateSMSAPI.Data Update Transaction Pin.
PasswordUpdateSMSAPI PasswordUpdateSMSAPI.Data User Password Update.


Bill Payment payload class BillPaymentSMSAPI.Data contains an attribute billProductId which identifies the type of bill involved in the transaction e.g, DSTV Bill, Airtime Recharge Bill, etc.
Below is a list of methods to get a corresponding billProductId

  • BillProductConstant.getAirtimeBillInfo(service: AirtimeService) to get Airtime bills product id.
  • BillProductConstant.getDataBillInfo(service: DataService) to get data bills product id
  • BillProductConstant.getInternetPlan(service: InternetService) to get internet bills product id
  • BillProductConstant.getTvBouquets(service: CabletvService) to get cable tv bills product id
  • BillProductConstant.getElectricityBillInfo(service: ElectricityService) to get electricity bills product id
