Nhs-website-content API returns 503/401 while hello-world works

Hello,

I’m experiencing an issue when trying to access the nhs-website-content API in both the Sandbox and Integration Test environments.

Summary:
At the moment, only the endpoint
https://sandbox.api.service.nhs.uk/hello-world/hello/application
is working correctly.

Requests to the nhs-website-content/conditions endpoint fail in both environments.

Application details:
Sandbox:
Application ID: 235af707-2189-4e23-9da1-b7e2736e48c8

Integration Test:
Application ID: d6b48413-d224-410a-b074-0689de050418

Sandbox behaviour:
Request:
GET https://sandbox.api.service.nhs.uk/nhs-website-content/conditions/
Headers:
Content-Type: application/json
apikey: *****

Response:
HTTP/1.1 503 Service Temporarily Unavailable

At the same time, the following request succeeds using the same API key:
GET https://sandbox.api.service.nhs.uk/hello-world/hello/application
Response:
HTTP/1.1 200 OK
{“message”:“Hello Application!”}

Integration Test behaviour:
Request:
GET https://int.api.service.nhs.uk/nhs-website-content/conditions/
Headers:
Content-Type: application/json
apikey: *****

Response:
HTTP/1.1 401 Unauthorized
Access Denied

From the response, it looks like the request may be blocked due to permissions or application configuration.

Could you please advise:

  • Whether the nhs-website-content API is currently available in Sandbox?

  • Whether additional permissions, products, or approvals are required for this API in the Integration Test environment?

  • If there are any known issues or restrictions affecting this endpoint?

Please let me know if you need any additional information from my side.

Thank you for your help.

Thank you for raising the above, we are aware of an ongoing issue with the integration environment and are working on a fix, I will also ask one of my team to reach out to ensure there is nothing else affecting your operations with the API.

Thanks

Molly

Hi Molly

I am wondering if the API access issue has been fixed. I also ran into 401 and 404 errors when I tried the NHS website content API in the integration test environment and 503 error in the sandbox environment today (23rd March 2025). Many thanks, Haymar

Hi Molly,

I’m also experiencing this issue as of today - although the problem seems to have started as of a few months ago in our testing environment which used to work perfectly.

Has this issue been resolved or could it be the same thing?

Thanks, David
