I have a scenario where I send a GET request to a broker and receive a FHIR response. When I attempted to use the built-in InterSystems functions to convert this FHIR response into SDA, the transformation failed—likely because it is not a standard FHIR request.

How should I handle this situation? Is there a recommended approach to processing FHIR responses in this context?

Additionally, if I manage to convert the FHIR response into a request format, I noticed that the broker sends a Task resource.

I understand that InterSystems provides functions to facilitate transactions between FHIR and HL7 via the SDA segment. My question is:

  • Does this transformation only work when InterSystems receives FHIR requests and converts them into HL7, or does it also support responses?
  • Specifically, if our operation sends a GET request to a broker and receives a FHIR response, does InterSystems support transforming this response into an SDA segment automatically?
  • Or should we manually parse and modify the response to handle it according to our needs?

What would be the best approach in this scenario?

Everytime I try to send a POST FHIR bundle I'm getting the following response: 404 Not Found. I'm not really sure why, although it works fine with a GET!

This is an example: 

 Response:

It might be something related to request path but not really sure.

And this is the HTTP service I'm using 

I tried this with Postman and it's working as expected

Am I missing something ?

Every time I try to update an SQL table using odbc connection, I'm getting: ERROR <Ens>ErrException: <MAX $ZF STRING>zPrepareW+1^%Library.SQLGatewayConnection.1

Set sqlStatement = "UPDATE dbo.Table1 SET OriginalMessageText="_OriginalMessageText_"WHERE Id='"_Id_"'"
$$$TRACE("SQL Statement: "_sqlStatement)

I know that the problem is with the length of the ORU HL7 message  (that contains OBX base64 PDF file ) I'm trying to update in the table, but is there a way to fix this? other than truncating the message ?

I also tried this statement but it didn't work as well


Set sql = "UPDATE dbo.Table1 SET

Dear,

I'm trying to configure a new interface that reads HL7, transform them into FHIR messages and then send POST or PUT or DELETE depending on HL7 doc type.

1-I added an HL7 TCP service that reads ADTs messages

2a-Send ADTs to a process to transform them into SDA  (using the following command:  do ##class(HS.Gateway.HL7.HL7ToSDA3).GetSDA(request,.con))

2b-Extract the patient MRN and add it to the AdditionalInfo property  (using the following request message class: HS.Message.XMLMessage)

3-Send the SDA message to the built in process: HS.FHIR.DTL.Util.HC.SDA3.FHIR.Process.

4-Send FHIR request to

We are in the process of installing a FHIR server on our InterSystems interface engine and have encountered a few questions. Your expertise and insights would be greatly appreciated:

  1. Automatic Handling of Requests and Responses:
    • Is installing a FHIR server sufficient to handle requests (POST, GET, PUT) automatically without manual intervention? Can we expect automatic creation and updating of resources based on incoming requests?
  2. Storage of FHIR Resources:
    • Where are FHIR resources typically stored?Is it in a database, global arrays, or another form?
