• Automated Billing – Reduces manual invoicing and payment collection.
• Improved Cash Flow – Ensures steady revenue streams with predictable payments.
• Enhanced User Experience – Offers customers convenience with hassle-free renewals.

Navigate to the wp-content/plugins/ directory and create a new folder:

/wp-content/plugins/subscription-payment-plugin/
    - subscription-payment-plugin.php
    - includes/
    - assets/
    - templates/

Step 2: Define Plugin Metadata

Inside subscription-payment-plugin.php, add the following header:

<?php
/*
Plugin Name: Subscription Payment Gateway Plugin
Plugin URI: https://example.com/
Description: A custom subscription-based payment gateway plugin for WordPress.

function register_subscription_payment_gateway($gateways) {
    $gateways[] = 'WC_Subscription_Payment_Gateway';
    return $gateways;
}
add_filter('woocommerce_payment_gateways', 'register_subscription_payment_gateway');

Step 4: Define the Payment Gateway Class

Create a class that handles recurring payments:

class WC_Subscription_Payment_Gateway extends WC_Payment_Gateway {
    public function __construct() {
        $this->id = 'subscription_payment';
        $this->method_title = __('Subscription Payment Method', 'woocommerce');
        $this->supports = array('subscriptions', 'subscription_cancellation', 'subscription_suspension', 'subscription_reactivation');
    }

    public function process_payment($order_id) {
        $order = wc_get_order($order_id);
        return array(
            'result'   => 'success',
            'redirect' => $this->get_payment_redirect_url($order),
        );
    }

    private function get_payment_redirect_url($order) {
        $return_url = site_url('/thank-you');
        return "https://example-subscription.com/checkout?amount=" . $order->get_total() . "&currency=USD&return_url=$return_url";

}
