Issue with eRS Healthcare Service Search API – ASID Configuration

e-Referral Service (e-RS)
1

We are currently facing an issue (ASID is not configured in the application) while invoking the ERS APIs on the INT environment. ERS team has asked us to reach out to the community forum.

API Endpoint:
/referrals/FHIR/STU3/HealthcareService/$ers.searchHealthcareServicesForPatient

Request Details:

ODS Code: F84033
Business Function: REFERRING_CLINICIAN
NHS Number: 9737786548
Request Type: APPOINTMENT_REQUEST

Summary of Issue:
The API call is returning the following error:

{
“resourceType”: “OperationOutcome”,
“meta”: {
“lastUpdated”: “2026-05-06T08:49:28.870Z”,
“profile”: [
“https://fhir.nhs.uk/STU3/StructureDefinition/eRS-OperationOutcome-1”
]
},
“issue”: [
{
“severity”: “error”,
“code”: “forbidden”,
“details”: {
“coding”: [
{
“system”: “https://fhir.nhs.uk/STU3/CodeSystem/eRS-APIErrorCode-1”,
“code”: “NO_ACCESS”
}
]
},
“diagnostics”: “ASID is not configured in the application”
}
]
}

We have included all required headers (including Authorization and correlation ID) and constructed the payload as per the specification. However, the request is being rejected due to ASID configuration.

Thanks Manish - we’ll get a request in to get that sorted for you. I’ll update on here.

@Manish_Kumar Could I just check which APPID you’re using for this call. My assumption is 7c90a3f3-01eb-4e93-8b90-7f788d0af035
