Order Metadata

When processing payments, the plugin stores metadata in WooCommerce orders.

Order Meta Fields

Meta Key	Type	Description
_gopay_id	string	GoPay transaction ID — unique payment identifier from GoPay
_gopay_data	array	Complete GoPay payment response data including gateway URL and payment details

Reading Data Examples

Getting Payment Info from an Order

$order = wc_get_order( $order_id );

// GoPay transaction ID
$gopay_id = $order->get_meta( '_gopay_id' );
// Result: "3048205082"

// Complete GoPay payment data
$gopay_data = $order->get_meta( '_gopay_data' );
// Result: array with full GoPay response (id, gw_url, state, amount, etc.)

Checking If an Order Was Paid via GoPay

$order = wc_get_order( $order_id );

if ( $order->meta_exists( '_gopay_id' ) && $order->is_paid() ) {
    $gopay_id = $order->get_meta( '_gopay_id' );
    // Order was paid via GoPay with transaction ID $gopay_id
}

Getting the GoPay Gateway URL

$order = wc_get_order( $order_id );

$gopay_data = $order->get_meta( '_gopay_data' );
$gw_url = $gopay_data['gw_url'] ?? '';
// Result: "https://gate.gopay.cz/gw/v3/..."

REST API Endpoints

The plugin registers two REST API endpoints for communication with GoPay:

Endpoint	Method	Description
/wpify-woo/v1/gopay	GET	Payment validation/callback — receives payment notifications from GoPay
/wpify-woo/v1/gopay/status	GET	Payment status check — verifies current payment status with GoPay

These endpoints are used internally by the GoPay payment gateway and should not be called manually.

Where to Place Your Code

You can add custom functions either in your child theme’s functions.php or use the Code Snippets plugin.
