• Payment Channels: Restrict payments to specific channels (e.g., card, bank, ussd).
• Custom Metadata: Attach additional data to transactions (e.g., order IDs).
• Split Payments: Split transaction amounts between your account and subaccounts.
• Consistent Responses: Handle success, error.ConcurrentModificationException, and cancel outcomes with a unified PaystackResponse model.
• WebView-Based Checkout: Displays Paystack’s payment UI securely within your app.
