Aangepaste Gateway-ontwikkeling

Je kunt aangepaste betalingsgateways maken door de Base_Gateway-klasse uit te breiden.

Gateway-klasse

class My_Custom_Gateway extends \WP_Ultimo\Gateways\Base_Gateway {

    public $id = 'my_gateway';

    public function __construct() {
        $this->title = 'My Payment Gateway';
        $this->description = 'Custom payment processing';
        $this->supports = ['one-time', 'recurring'];

        parent::__construct();
    }

    public function process_single_payment($payment, $cart, $order) {
        $result = $this->api_call('charge', [
            'amount' => $payment->get_total(),
            'currency' => $payment->get_currency(),
            'customer' => $payment->get_customer_id()
        ]);

        if ($result->success) {
            $payment->set_gateway_payment_id($result->transaction_id);
            $payment->set_status('completed');
            return true;
        }

        return new WP_Error('payment_failed', $result->error_message);
    }

    public function process_signup($membership, $customer, $cart, $order) {
        $subscription = $this->api_call('subscription/create', [
            'customer_id' => $customer->get_gateway_customer_id(),
            'plan_id' => $membership->get_plan()->get_gateway_plan_id(),
            'trial_days' => $membership->get_trial_days()
        ]);

        if ($subscription->success) {
            $membership->set_gateway_subscription_id($subscription->id);
            return true;
        }

        return new WP_Error('subscription_failed', $subscription->error);
    }
}

Gateway registreren

add_filter('wu_payment_gateways', function($gateways) {
    $gateways['my_gateway'] = 'My_Custom_Gateway';
    return $gateways;
});

Belangrijke methoden

Methode	Doel
process_single_payment()	Verwerk eenmalige betalingen
process_signup()	Stel terugkerende abonnementen in
process_refund()	Verwerk terugbetalingsverzoeken
get_payment_methods()	Retourneer opgeslagen betaalmethoden voor een klant

Tips

• Returner altijd WP_Error bij een fout zodat Ultimate Multisite de foutweergave kan afhandelen
• Stel $this->supports in om aan te geven welke betalingsvormen jouw gateway ondersteunt (one-time, recurring)
• Gebruik wu_log_add() voor gateway-specifieke logging
