Usage

You can use in two ways, either register the SDK in your application:

1. Via Dependency Injection

builder.Services.AddMonnify(options => 
{
    options.ApiKey = builder.Configuration["MonnifyOptions:ApiKey"];
    options.SecretKey = builder.Configuration["MonnifyOptions:SecretKey"];
    options.BaseUrl = builder.Configuration["MonnifyOptions:BaseUrl"];
});


public class PaymentService {
    private readonly IMonnifyClient _monnifyClient;

    PaymentService(IMonnifyClient monnifyClient) {
        _monnifyClient = monnifyClient;
    }

    public YourResponse InitiatePayment(Request request) {
        var response = _monnifyClient.Transaction.InitiateTransaction(request);
        ...
    }
}

2. or simply create a new instance of MonnifyClient

var monnifyClient = new MonnifyClient(new MonnifyOptions
{
    ApiKey = "{{API_KEY}}",
    ApiSecret = "{{API_SECRET}}",
    BaseUrl = "{{BASE_URL}}"
})

var paymentRequest = new InitiatizeTransaction
{
    Amount = 5000.00m,
    CurrencyCode = "NGN",
    CustomerEmail = "[email protected]",
    CustomerName = "John Doe",
    PaymentReference = Guid.New().ToString(),
    PaymentDescription = "Test Payment",
    ContractCode = "1438045810",
    RedirectUrl = "https://your-site.com/payment-callback"
};


var response = await monnifyClient.Transaction.InitiateTransaction(paymentRequest);
...
