Authentication

Paystack authenticates API requests using your account’s secret key, which you can find in the Paystack Dashboard (Settings > API Keys & Webhooks)

Use Configure method in PaystackConfiguration to set the Secret Key and the Base URL if needed.

PaystackConfiguration.Configure("sk_test_...");

Examples

Initialize a Transaction

using Paystack.NET.Configuration;
using Paystack.NET.Services.Transactions;
using Paystack.NET.Models.Transactions.Options;

PaystackConfiguration.Configure("sk_test_...");

var transactionService = new TransactionService();

var initializeOptions = new InitializeTransactionOptions
{
    Reference = "TEST-" + DateTime.Now.ToString("yyyyMMddHHmmss");
    Amount = 5000, // Amount in pesewas
    Email = "customer@example.com"
};

var response = await transactionService.Initialize(initializeOptions);
Console.WriteLine($"Transaction Reference: {response.Data.Reference}");

Verify a Transaction

var reference = "TRANSACTION_REFERENCE_HERE";
var response = await transactionService.Verify(reference);

if (response.Data is { Status: TransactionStatus.Success })
{
    Console.WriteLine("Transaction successful!");
}

Setup a Callback (Webhook)

using Paystack.NET.Services.Callback;


var requestBody = "{ ... }"; // Raw request body from Paystack webhook
var signatureHeader = "X-Paystack-Signature header from request";

var callbackService = new CallbackService();

try
{
    var callback = callbackService.HandleCallback(requestBody, signatureHeader);
    Console.WriteLine($"Event: {callback.Event}");
    Console.WriteLine($"Data: {callback.Data}");
