Добавление метода оплаты (платежного шлюза) в WooCommerce

Для добавления нового метода оплаты в WooCommerce можно воспользоваться API WooCommerсe. Вот пример кода, который добавляет простой оффлайн платежный шлюз:

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


add_action( 'plugins_loaded', 'wc_offline_gateway_init', 11 );

function wc_offline_gateway_init() {

	class WC_Gateway_Offline extends WC_Payment_Gateway {

		/**
		 * Constructor for the gateway.
		 */
		public function __construct() {
	  
			$this->id                 = 'offline_gateway';
			$this->icon               = apply_filters('woocommerce_offline_icon', '');
			$this->has_fields         = false;
			$this->method_title       = __( 'Offline', 'wc-gateway-offline' );
			$this->method_description = __( 'Allows offline payments. Very handy if you use your cheque gateway for another payment method, and can help with testing. Orders are marked as "on-hold" when received.', 'wc-gateway-offline' );
		  
			// Load the settings.
			$this->init_form_fields();
			$this->init_settings();
		  
			// Define user set variables
			$this->title        = $this->get_option( 'title' );
			$this->description  = $this->get_option( 'description' );
			$this->instructions = $this->get_option( 'instructions', $this->description );
		  
			// Actions
