Hi,

Directed here by the eRS API partners.

Trying to use the integration environment, starting with A008 retrieve the worklist. We’re unsure about what value we should be providing for the service value under system “[http://fhir.nhs.net/Id/ers-service”](http://fhir.nhs.net/Id/ers-service%E2%80%9D).

Currently getting a 422 - No Relationship error on A008 providing service value “6167685”

I assume some test services will have been set up as part of our test data pack but I’m struggling to find documentation about how we can retrieve these without A035. Which itself gives a “REC\_FORBIDDEN” error as “Endpoint not authorised for Business Function (PROVIDER\_AUTHORISED\_APPLICATION).”

Application ID : 16c73bd9-30b2-4edf-b72e-9a93b4cb5ef1

Let me know if more detail is required

Cheers,

---

Hi @James_Elliott - Welcome to the community and thanks for reaching out.

Your test data pack does not include e-RS services or referral data.

The intention is that partners create and manage services yourselves.

We have guides for creating services and referrals:

[https://digital.nhs.uk/services/path-to-live-environments/guide-to-creating-services-in-path-to-live-nhs-e-referral-service](https://digital.nhs.uk/services/path-to-live-environments/guide-to-creating-services-in-path-to-live-nhs-e-referral-service)

[https://digital.nhs.uk/services/path-to-live-environments/guide-to-creating-referrals-in-path-to-live-nhs-e-referral-service](https://digital.nhs.uk/services/path-to-live-environments/guide-to-creating-referrals-in-path-to-live-nhs-e-referral-service)

The service ID will be available to you once a service is created/published.

Thanks,  
Z.
