Extending Payment Gateways
VTUPress gateways (like Paystack, Monnify, etc.) are structured identically. They all extend the abstract class `Vtupress_Gateway`.
Base Class: `Vtupress_Gateway`
**File:** `includes/gateway_class.php`
To create a new payment gateway (e.g., “Flutterwave” or “Stripe”):
1. Create a class extending `Vtupress_Gateway`.
2. Hook into `vtupress_gateway_registry`.
Example: Adding a Custom Gateway
—
“`php
class Stripe_Gateway extends Vtupress_Gateway {
public function __construct() {
$this->id = ‘stripe’;
$this->name = ‘Stripe Payment’;
$this->has_webhook = true;
}
public function initialize_payment($amount, $user_id) {
// Logic to redirect user to Stripe checkout
}
public function process_webhook($payload) {
// Handle Stripe IPN / Webhooks here
}
}
// Register the gateway
add_filter(‘vtupress_gateway_registry’, function($registry) {
$registry[‘stripe’] = ‘Stripe_Gateway’;
return $registry;
});
