I have been struggling sometime with trying to take a FHIR Bundle Response, extract the "entry.resourceType", extract the MRN and Name from the Patient FHIR Response...

Going through learning.intersystems.com, it suggested that I try using fhirPathAPI to parse and search my response for certain values, however I am not sure my syntax is correct. Using the AI code, it suggested to set my tree = "Bundle.entry.resource.resourceType"

So I have been working in Healthcare Interops for about a month now and in IRIS. I am looking to implement SMART on FHIR and I am currently working to make an endpoint that works as the discovery endpoint. It is a custom dispatch class and unauthenticated is selected for access. I am trying to make a simple get request from Postman to test that the proper JSON is sent, but I receive a 403 Forbidden error. It is reaching IRIS it seems so I know its not a reverse proxy error. Here is an example of my custom Dispatch Class. Then also there is a screenshot of my web application I made specifically

I am receiving a FHIR response bundle back with a resource of patient. Using fromDao, I attempted to take the stream and put it into FHIRModel.R4.Patient but it is not mapping correctly. When I attempt to take FHIRModel.R4.Patient and write it out using toString(), all I am seeing is the resource

{"resourceType":"Patient"}

so the response is not mapping correctly to FHIRModel.R4.Patient. How have others handled this? Do I need to translate it to an SDA since it does fit the model format?

I have built a REST operation to submit a JSON Request Body, and in the JSON Response Object, I need to pull out certain values like pureID, portalURL, and under the identifiers array the ClassifiedID that has a term."en_US" = "Scopus Author ID"

Hi noble devs!

Just building a simple frontend->JSON->IRIS backend story, and figured that IRIS while importing via %JSON.Adaptor wants JSON fields to match property names, meaning even should match the case. Like:

{ name: "John", 

surname: "Doe"}

will have issues while saving the dynamic object to a class Sample.Person with:

Class Sample.Person Extends (%Persistent, %JSON.Adaptor)

{

Property Name: %Sting;Property Surname: %String;
}

As soon as the case is not the same... 

Introduction

InterSystems IRIS allows you to build REST APIs using ObjectScript classes and the %CSP.REST framework. This enables the development of modern services to expose data for web apps, mobile apps, or system integrations.

In this article, you'll learn how to create a basic REST API in InterSystems IRIS, including:

• A persistent data class
• A REST class with GET and POST methods
• A web application to expose the API
• A full demonstration using Docker

Step 1: Create the data class Demo.Producto

Hello Community,

When handling a %CSP.REST API response for a custom endpoint, how can I capture or access the response content before it is written to the output buffer and sent through the Web Gateway to the UI?

In manually created REST services (for example, with a route like:<Route Url="/test" Method="POST" Call="User.Sample:Test" Cors="true"/> ),
the response is typically written from within any class method in the execution flow.

Is there a way to intercept or log the response content before it is sent to the client?

Thanks!

Hi developers!

Observing the avalanche of AI-driven and vibe-coding developer tools that have been appearing lately almost every month with more and more exciting dev features, I was puzzled whether it is possible to leverage it with InterSystems IRIS. At least to build a frontend. And the answer - yes! At least with the approach I followed.

Here is my recipe to prompt the UI vs InterSystems IRIS Backend:

1. Have the REST API on the IRIS side, which reflects some Open API (swagger) spec.
2. Generate the UI with any vibe-coding tool (e.g., Lovable) and point the UI to the REST API endpoint.
3. Profit!

It shows how to iterate over object, get property values and their paths.

Hi everyone,

I’m new to this community and could really use some help with creating a production in InterSystems IRIS for Health Community 2024.3. I have deployed my instance using Docker.
Here’s what I’m trying to do:

1. Input: I have an HL7 file that is processed by the standard EnsLib.HL7.Service.FileService.
2. DTL Transformation: I’ve created a DTL to transform the HL7 content into a custom class like this:

For a long time I have wanted to learn the Django framework, but another more pressing project has always taken priority. Like many developers, I use python when it comes to machine learning, but when I first learned web programming PHP was still enjoying primacy, and so when it was time for me to pick up a new complicated framework for creating web applications to publish my machine learning work, I still turned to PHP. For a while I have been using a framework called Laravel to build my websites, and this PHP framework introduced me to the modern Model-View-Controller pattern of web

IRIS supports CCDA and FHIR transformations out-of-the-box, yet the ability to access and view those features requires considerable setup time and product knowledge. The IRIS Interop DevTools application was designed to bridge that gap, allowing implementers to immediately jump in and view the built-in transformation capabilities of the product. 

In addition to the IRIS XML, XPath, and CCDA Transformation environment, the Interop DevTools package now provides:

Hi Community,
In this article, I will introduce my application iris-fhir-bridge 
IRIS-FHIR-Bridge is a robust interoperability engine built on InterSystems IRIS for Health, designed to transform healthcare data across multiple formats into FHIR and vice versa. It leverages the InterSystems FHIR Object Model (HS.FHIRModel.R4.*) to enable smooth data standardization and exchange across modern and legacy healthcare systems.

I am struggling on how to pull out individual fields from a JSON. In a previous post someone had mentioned that I could...

Hi everyone,

It's me again😁. As usual I would like to share something I study recently, and today, I would like to share about the document DB😁.

1st of all, let's go to the documentation https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls?KEY=GDOCDB_intro
Well, I must say, this one is much better to follow than the others, which I read before. 😭 Finally😭😭

Ok, let's start walking through it together

Here we go😀, we start a terminal from VSCode to connect to our IRIS

We are going to created Document DB demo.docpatient

Foreword

InterSystems IRIS versions 2022.2 and newer feature the ability to authenticate to a REST API using JSON web tokens (JWTs). This feature enhances security by limiting where and how often passwords transfer over the network in addition to setting an expiration time on access.

The goal of this article is to serve as a tutorial on how to implement a mock REST API using InterSystems IRIS and lock access to it behind JWTs.

I am running into an issue where a JSON response is missing keys...

{
    "count": 0,
    "pageInformation": {
        "offset": 0,
        "size": 10
    },
    "items": []
}

Within the JSON response I am only looking for two fields portalUrl and portalId. I have tried using $LENGTH and %IsDefined to check if they are valued but neither work. 

Hello Community,

Hello everyone,

I am using a class that inherits from %RegisteredObject and %JSON.Adaptor to generate a JSON string from its instances.

However, one of the properties in my class is of type %Library.DynamicObject, as in the example:

Class Faces.Option Extends (%RegisteredObject, %JSON.Adaptor)
{ 
Property legend As %String;Property xAxis As %Library.DynamicObject; 
}

Hi devs!

Suppose I have an instance of a persistent class:

Set person = ##class(dc.Sample.Person).%OpenId(1)

Class is an ancestor of %JSON.Adapter.

How can I convert it to dynamic object with the properties that person.%JSONExport() provides?

{"Name":"Elon Mask","Title":"Associate Accountant","Company":"InterSystems","Phone":"799-933-5569","DOB":"1926-12-11"}

Couldn't find a right method. 

The Good Old Days

The %Library.DynamicObject class has been in IRIS since before it became IRIS. If you have been using it since the Cache days, you may want to brush up on some of its changes.

In Cache 2018, the %Get method only had one argument. It was the key to retrieving from the JSON, meaning that if your JSON object called myObj, it would look like the following:

Hi devs!

What is the best way to return JSON in IRIS for a GET request in a REST app?

This is how I do it now:

Hi Community,

How Can I do to return ID when I call %JSONExport()?

Say I have an ObjectScript object called Book. It has 2 properties title and author. It extends JSON.%Adaptor, so I can call book.%JSONExport() and get this output:

In my web service I want to have a search function that returns an array of Books along with the total number of responses, like this:

DP-439207 - AIX JSON Unicode Parsing Issue

Background:

This guideline provides an overview of how to design and implement a REST API interface for querying patient demographic data from an Electronic Patient Record (EPR) system using HealthConnect. The process involves sending a query request with the patient's identification number, retrieving the response from the EPR system, extracting the required patient demographic data from the HL7 message, and sending it as a JSON response to the supplier. The high-level process diagram is shown below (Screenshot 1).

 JSON Web Token (JWT) Authentication

Hi Everyone,

I would like to share the code and step-by-step instructions/or guideline for generating a JWT (JSON Web Token) signature, as well as how to test it using Postman / HealthConnect.

JWT is an open standard (RFC 7519) that defines a compact, URL-safe method for securely transmitting information between parties in the form of a JSON object.

Structure of a JWT:

A JWT consists of three parts, separated by dots (.):
