Snomed CT question

General enquiries
1

Hello,

Sorry I wasn’t sure which section to put this in.

I’m looking at doing some development with the Technology server API to get Snomed data. Firstly the only URL I seem to be able to find is the production API https://ontology.nhs.uk/production1/ Is there a development/staging API I should be using instead?

Secondly I tried searching for a Snomed code with the following request:

https://ontology.nhs.uk/production1/fhir/CodeSystem/$lookup?system=http://snomed.info/sct&code=228557008&_format=json

I get a JSON response telling me that the code doesn’t exist however if I search using the Snomed browser SNOMED CT - Home it looks like the code exists.

I’m not sure why I’m getting different information from the API and the browser? Maybe I’m using the wrong URL for the API?

Thanks

Hi @as140 thanks for posting. Have you been to the Terminology Server - FHIR APIs - NHS England Digital page in the API and Integration Catalogue? There are some links to some alternative environments on this page. There is further information which may help for your specific use case on the terminology server page in the Service Catalogue The NHS England Terminology Server - NHS England Digital

Hello,

Thanks for your reply.

I’d found https://digital.nhs.uk/services/terminology-server/environments from the link you provided before creating my forum post but I didn’t notice that the information about using production1 for testing is on the other linked page https://digital.nhs.uk/services/terminology-servers#how-to-get-access

Thanks for your help with that question.

For my second question I tried to combine the production1 environment link with the “lookup a snomed code” example I found here Ontoserver 6.0: example FHIR Terminology requests (linked from https://digital.nhs.uk/services/terminology-server/training-guides/integrate-my-system-with-the-terminology-server/developer-launchpad#example-requests).

Have I misunderstood which examples to use with the production1 link?

Thanks
