# Merchant checkout

Galaxy Pay offer pre-built payment pages that are designed to enhance the integration process and save you the time and effort required to create custom payment pages. The integration via API is simple and quick. You do not need to handle or store any payment details, which helps to lower PCI compliance costs.  

How it works: when your customers have finished adding items to their shopping cart on your website, they will be seamlessly redirected to Galaxy Pay's user-friendly payment pages. This redirection ensures a smooth and efficient payment experience. Your customers can then securely submit their payment information through our reliable API. To start the integration process with ease, we recommend referring to our comprehensive guide on how to integrate with [GalaxyPay Hosted Checkout ](/upc/payment-gateway/api-specification/payment/pay.md)
