Most Payment Service Providers offer several integration methods and ways to accept payments online. They all provide a hosted payment page, the easiest way to take payments. This allows merchants to simply redirect their shoppers and customers to the secure payment page of the Payment Service Provider. There the customer selects their preferred payment method and pays.
The hosted payment page can also be injected into the merchant's website through a so-called i-frame. This allows merchants to keep customers within their own website and provide a better customer experience.
Next to using the hosted payment page, most Payment Service Providers provide APIs and SDKs for merchants (read developers) to connect. Larger merchants with in-house developers or outsourced web agencies often make use of API and SDK integration as it allows for further customization. By being able to fully control the payment checkout, they can provide the best and seamless experience to their customers.
