Users can access the NHS Digital Terminology Server with a registered account (authenticated) or without a registered account (Non-authenticated).
Guidance for how to register for an account is provided in the Account Management training guide. The Terminology Server can be accessed from https://ontology.nhs.uk.
If you wish to access the Terminology Server from a software application or to syndicate content to your own terminology server, rather than access via a browser, you will need a system-to-system account. Complete a System to system account request form to request an NHS Digital Terminology Server system-to-system account.
