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.
