Welcome to the Fiserv developer documentation, this section will give you an overview of what's on offer! We provide solutions which cover the full spectrum of payments, enabled by our range of APIs.

Our payments solutions enable you to accept your customers' preferred payment methods (for a full list see [here](🔗)) in a variety of different ways from seamless hosted page integration, to fully customizable APIs.

The documentation in this area is mostly broken down by either the technical interface (such as an API, SDK or web component) and the features. If you're new to us, or to payments in general, we really recommend making a note of our [General Concepts](🔗) page.

This page gives an overview of the different options and which one might be most appropriate for your use case.
