Custom WooCommerce Gateway - wordpress

Question

I`m trying to develop a custom payment gateway for WooCommerce plugin, but I have a problem with the checkout page. What I want is to insert a form on the checkout final step page that is submitted automatically after 5 seconds.
My code is:
...
add_action('woocommerce_receipt_' . $this->id, array($this, 'receipt_page'));
add_action('woocommerce_api_wc_' . $this->id, array($this, 'handle_callback'));
}
function handle_callback() {
wp_die('handle_callback');
}
function receipt_page( $order )
{
echo "receipt page";
$this->generate_submit_form_elements( $order );
}
The problem is that "receipt_page" action is not triggered.
Thanks!

oh, its because you forgot to set the has_fields flag to true.
//after setting the id and method_title, set the has_fields to true
$this -> id = 'kiwipay';
$this -> method_title = 'KiwiPay';
$this->has_fields = true; // if you want credit card payment fields to show on the users checkout page
then in the process_payment function put this:
// Payload would look something like this.
$payload = array(
"amount" => $order.get_total(),
"reference" => $order->get_order_number(),
"orderid" => $order->id,
"return_url" => $this->get_return_url($order) //return to thank you page.
);
response = wp_remote_post( $environment_url, array(
'method' => 'POST',
'body' => http_build_query( $payload ),
'timeout' => 90,
'sslverify' => false,
) );
// Retrieve the body's response if no errors found
$response_body = wp_remote_retrieve_body( $response );
$response_headers = wp_remote_retrieve_headers( $response );
//use this if you need to redirect the user to the payment page of the bank.
$querystring = http_build_query( $payload );
return array(
'result' => 'success',
'redirect' => $environment_url . '?' . $querystring,
);
