  • Gateway must support "redirect" or "form submission" way of payment to redirect user to checkout page.
  • Gateway must support custom price and items definition (ie 2Checkout does not support this, they require products to be created in their system first)
  • Our team does not integrate solutions where it's required to build form to enter credit card details (and process payment on background: server-to-server) due to security concerns of such solution.

Please discuss your gateway integration with support team prior purchasing this service.
