Integration effort	Single redirect or inline widget	Single integration for 4 markets

The integration patterns differ in how payment method selection is handled:

Paystack (Kenya):

// Paystack — initialize with channel preference
var response = await fetch('https://api.paystack.co/transaction/initialize', {
  method: 'POST',
  headers: { Authorization: 'Bearer ' + process.env.PAYSTACK_SECRET_KEY, 'Content-Type': 'application/json' },
  body: JSON.stringify({
    email: customerEmail,
    amount: amountInKobo,
    currency: 'KES',
    channels: ['mobile_money', 'card', 'bank_transfer'],
    callback_url: 'https://yourapp.com/verify',
  }),
});
// Paystack checkout presents M-Pesa + card options

Pesapal (multi-country East Africa):

// Pesapal — IPN (Instant Payment Notification) based flow
// 1. Submit order to Pesapal API with IPN URL
// 2. Redirect customer to Pesapal checkout (shows mobile money per their country)
// 3. Pesapal sends IPN callback to your server on payment
// 4. Query Pesapal API to confirm payment status

var orderData = {
  id: orderId,
  currency: 'KES', // or UGX, TZS, RWF per market
  amount: amount,
  description: 'Order payment',
  callback_url: 'https://yourapp.com/pesapal/callback',
  notification_id: ipnId, // register IPN endpoint first
  billing_address: { email: customerEmail },
};
// POST to /api/Transactions/SubmitOrderRequest

Paystack's flow is cleaner for developers used to modern REST APIs. Pesapal's IPN flow is older in design but covers markets Paystack cannot. For a Kenyan-only product, Paystack is easier. For Uganda + Tanzania + Kenya, Pesapal saves you building three separate gateway integrations.
