Application Programming Interface (API) - NHS e-Referral Service

Find out more about our API and how to connect systems to the e-Referral Service.


Welcome to the e-Referral Service (e-RS) API site.

Within these pages you'll find everything you need to know about our API and integrating with e-RS.

We'll be adding more content over time. Contact us at [email protected] to provide feedback, if you can't find what you're looking for or if there is anything specific you would like to see.

API overview

e-RS is a web-based platform. It allows healthcare professionals to refer patients for specialist treatment, manage referrals and provide advice and guidance.

One of the key features of e-RS is its use of an API.

An API allows communication and information to be shared between two systems.

This means that it is possible to access e-RS functionality, or data, within a system that utilises our API without having to use e-RS in a web browser.


The intended audience for this site includes, but not limited to:

  • Healthcare organisations
  • IT system developers and suppliers
  • Internal NHS England programmes
