If you want to use 2Checkout, you need first to create a Merchant Account: https://www.2checkout.com/ecommerce-glossary/merchant-account After this, sign in and in Account -> Site Management add for Approved URL this: http://yourdomain.com/user/success-payment Copy account number and secret word and add in Admin -> Settings -> Payments.
