E-Commerce

Nexi supports online payment acceptance through a range of flexible e-commerce solutions, enabling merchants to accept payments securely across websites, mobile applications, and remote channels.

At the core of our offering is Nexi Paygate and Nexi Easy, two in-house payment gateways, fully integrated with Nexi acquiring. These gateways allow merchants to manage payment processing, reporting, and settlement within a unified environment.

In addition, several Swiss payment service providers (PSPs) support Nexi acquiring, including Datatrans, Wallee, and PostFinance Checkout. These platforms offer a variety of integration models, allowing merchants to choose the approach that best fits their technical setup and customer experience.

Integration Models

Depending on the business model and technical capabilities, online payments can be integrated in different ways:

Hosted Payment Page

Customers are redirected to a secure payment page hosted by the provider. This approach requires minimal integration effort and is the fastest way to start accepting payments. It follows the standard checkout flow where customers are redirected to a payment page and then returned to the shop.

Embedded / API Integration

Payment forms are integrated directly into the merchant’s website or application. This provides greater control over the user experience and branding, while requiring more development effort.

In-App Payments

Payments are handled directly within a mobile application using dedicated SDKs. This enables a seamless in-app checkout experience for customers, directly within iOS and Android applications.

Pay by Link

Payments are initiated by sending a payment link to the customer (e.g. via SMS, email, or messaging apps). This is particularly useful for remote sales, customer support scenarios, or businesses without a full online shop.

Security and Compliance

All e-commerce solutions follow industry security standards, including PCI DSS requirements and strong customer authentication (SCA) where applicable. Sensitive payment data is handled securely by the gateway or PSP, reducing the compliance burden for merchants.

Choosing the Right Setup

The most suitable solution depends on several factors, including:

• Technical capabilities and resources
• Desired level of checkout customization
• Supported payment methods
• Sales channels (web, mobile, remote)

It is recommended to align with Nexi early in the process to determine the optimal setup based on your business needs and integration requirements.
