Things You Should Know First


This section helps you to understand the elements for your solution's integration such as which integration method to use, how to configure your account to perform each integration, how to use the custom fields, how to calculate the hash parameters of requests and responses, etc.

The Hosted Page Integration Method


The Hosted Page (HP) is an integration method where the entry of some sensitive data is handled by the Payment Gateway so the merchant’s servers are not exposed to this data. This is advisable so as to reduce the security overhead of the integrated solution. For this scenario, Nuvei becomes the responsible party for maintaining the security and integrity of the sensitive data sent to these pages.

These Hosted Pages are also highly stylized so that they look more appealing to the customers and improves their overall experience. For more details on that consult Pay Pages.

Cardholders are redirected to a page at the Payment Gateway. Upon the customer clicking the ‘submit’ button on that page, all data are collected, processed and the Payment Gateway sends the processing result back to the Merchant's site, also redirecting the Account Holder to the Merchant's result page, in a transparent way.

The following features are available for this integration method:

The RESTful Integration Method

Our APIs are built around REST principles and OpenAPI Specification definitions. Complying to such industry standards means that we can offer developers a much better experience by exposing predictable resource-oriented URL's as well as a comprehensive range of HTTP response codes and verbs. Moreover, you have the possibility to enable and take full advantage of HATEOAS controls to provide out-of-the-box Discoverability and Functional-Awareness for your integrations.
