Payment Express provides merchants with several interfaces for developing custom built payment pages. PxPost is designed to handle transactions using a HTTPS Post Request. There is no Payment Express software needed on the client side, making its platform and language independent, allowing greater flexibility and interoperability.
This method will allow you to transact using credit cards on your own website without redirecting to a remote payment page. You will require SSL certification and additional merchant compliance requirements to use this method.
