Problem in develop Custom Payment Provider about oc-microcart-plugin HOT 1 OPEN

SaferPay and PayPal both redirect you to an external page.

Simply register your class as callback:

        Session::put('microCart.payment.callback', self::class);

and return the target URL:

        return $result->redirect('http://whatever.com');

This way, you will be redirected to the provided url. Make sure to pass $this->returnUrl() to the payment provider so you will be redirected back to the correct URL.

Once you are redirected back, the complete method will be executed.
