Overview

Welcome to the developer documentation, NatWest has partnered with Fiserv to provide our customers new, improved and flexible ways of integrating into our Payment gateway and accepting payments. This section will give you an overview of what's on offer! This new collaboration allows NatWest to provide our merchants a range of solutions which cover the full spectrum of ecommerce payments, enabled by a range of APIs.

Our payments solutions enable you to accept your customers' preferred payment methods in a variety of different ways from seamless hosted page integration and secure payment links to fully customizable APIs.

The documentation in this area provides all the necessary details to use the API effectively.

If you are an existing NatWest customer and you wish to use our API’s, first you will need to register and request access credentials, take a look at the Getting Started section for step-by-step guide on how to do this.

If you're new to us, or to payments in general, we really recommend making a note of our General Concepts page, it gives an overview of the different options and which one might be most appropriate for your use case.

For any support queries you may have regarding your integration you can contact our Technical support team directly by email: [email protected]
