WooCommerce Custom Payment Gateway Refund Issue – Page Not Reloading

Hello everyone,

I’m developing a custom payment gateway for WooCommerce that integrates with SATIM (payment operator in Algeria). Everything works fine, including processing payments and refunds. However, I encounter an issue with the refund process where the loading icon keeps spinning indefinitely, even though the refund is processed successfully, and I receive the confirmation email, refunded status.

Here are the details of my setup:

The refund is processed correctly, and the status is updated in WooCommerce.
I receive a 200 success response from the SATIM API.
There are no errors in the console or logs.
Code Overview:

Here’s the relevant part of my gateway class where I handle the refund:

public function process_refund($order_id, $amount = null, $reason = '') {
    $order = wc_get_order($order_id);
    if (!$order) {
        return false;
    }

    if ($amount < 50) {
        $notice = sprintf(esc_html__('Refund amount is less than 50%s'), $this->currency_symbol);
        $this->log($notice);
        $order->add_order_note('Refund Failed: ' . $notice);
    } else {
        $args = [
            'body' => [
                'userName' => $this->userName,
                'password' => $this->password,
                'orderId' => $order->get_transaction_id(),
                'amount' => $amount * 100
            ]
        ];
        $response = wp_remote_get(add_query_arg($args['body'], $this->api_refund_url));
        $this->log(is_wp_error($response) ? $response : $response['body']);
        if (!is_wp_error($response)) {
            $response = json_decode($response['body'], true);
            $response_code = intval($response['errorCode']);
            $refund_message = intval($response['errorMessage']);

            if ($response_code == 0) {
                $refund_message = sprintf(esc_html__('Refunded %s%s'), $amount, $this->currency_symbol);
                $this->log('Success: ' . wp_strip_all_tags($refund_message));
                $order->add_order_note( $refund_message );

                // Tried various methods to reload the page here

                return true;
            } else {
                $this->log('Refund Failed: ' . $refund_message, 'error');
                $order->add_order_note('Refund Failed: ' . $refund_message);
                return false;
            }
        }
    }
}

What I’ve Tried:

JavaScript Injection:
I attempted to inject JavaScript to reload the page using echo ‘<script type=”text/javascript”>window.location.reload();</script>’;, but it didn’t work.

Redirect with PHP:
Using wp_safe_redirect followed by exit to reload the page, but it seems WooCommerce’s AJAX handling doesn’t allow for PHP redirections directly.

Admin Footer Action:
Added a script in admin_footer to check a flag and reload the page, but this didn’t resolve the issue either.

Question:
How can I properly reload the WooCommerce admin page after a successful refund to stop the loading icon from spinning indefinitely? Has anyone encountered a similar issue or have any suggestions on how to resolve this?

Thank you in advance for your help!
