Representational state transfer (REST) is a software architectural style that defines a set of constraints to be used for creating Web services. Web services that conform to the REST architectural style, called RESTful Web services (RWS), provide interoperability between computer systems on the Internet. RESTful Web services allow the requesting systems to access and manipulate textual representations of Web resources by using a uniform and predefined set of stateless operations. Other kinds of Web services, such as SOAP Web services, expose their own arbitrary sets of operations.
I have a primary dispatch class that implements %CSP.REST.AccessCheck() for some high level access checks before the route table forwards the request to the implementation classes which also implement %CSP.REST.AccessCheck() for some lower level access checks. The idea is that we know where we are in the implementation class and what the user is trying to do, so it makes more sense to check some lower level items there rather than trying to parse out the request at the dispatch class.
My main goal of this article was to prove the use of InterSystems IRIS for Health for REST FHIR interoperability between multiple applications. In this use case, some initiating application makes a REST call to IRIS for Health (which is merely a passthrough for REST calls) to retrieve FHIR data from an Oracle Health R4 FHIR repository. Ideally, it simplifies the syntax for calling the Oracle Health APIs.
I'm modifying a REST interface for a client but it seems impossible to me to modify HTTP Response Status and including custom HTTP Headers either.
My dispatch class (extending %CSP.REST) is contacted through a POST request and the latter is processed in a custom class (extending %CSP.REST as well) accessed as shown in the example below:

We've got some web services that utilise EnsLib.SOAP.Service/EnsLib.REST.Service. These do some further requests to a few operations to call some other services and return the combined results.
An issue that we are noticing is that some of the usage involves users hitting the refresh button a few too many times and generating a lot of requests. This is mostly an issue when the service that the operations are calling are down or slow to respond. IRIS starts using a lot of RAM when this occurs and has caused outages by getting through an extra 50-60GB of RAM.
OpenAPI-Client Gen has just released, this is an application to create an IRIS Interoperability Production client from Swagger 2.0 specification.
Instead of the existing tool ^%REST that creates a server-side REST application, OpenAPI-Client Gen creates a complete REST Interoperability Production client template.
I have an API set up in IRIS which is secured using an IRIS authentication service, so there is a bearer token being passed down in the request header.

I'm trying to use JWT authentication on a REST application in IRIS. The login API are correctly "injected" into the application. Login works fine with Postman and other REST clients, and subsequent calls to my REST API using the bearer token work fine (correctly authenticated). So far, so good.
This demo program is used to show how a custom FHIR profile can be employed to validate data compliance. The custom FHIR implementation guide was developed based on FHIR Version R4, and in this example implements the Organization resource extension to validating data compliance.
When passing on the content of a file in a REST API call, I need to put the original file name in an HTTP header. As it happens, some file names have non-8-bit characters in them ("å", "ö", and the like), and these arrive garbled on the other side. Does anybody know the correct way to encode them (assuming they should be encoded at all)?
$zconvert(filename, "O", "UTF8") does not appear to be it. I'm leaning towards $zconvert(filename, "O", "URL"), but leaning isn't good enough.
There are many applications for working with HL7 V2 messages, but the tools for working with XML in IRIS Management Portal and Cache Studio are limited.
Managing databases and performing CRUD operations are fundamental tasks for developers building data-driven applications. While many database management systems (DBMS) exist, they can be complex and cumbersome to interact with, especially when it comes to creating databases and tables, handling constraints, and performing real-time data operations through an API.
In this article, we’ll dive into the inner workings of the database management tool, exploring the architecture and technologies that power it. Understanding how the application functions behind the scenes will give you insight into its design, how it manages databases, tables, and how the API interacts with data.
I sent a http post message with a large message body (approx. 200 kB) to a standard EnsLib.REST.GenericService using a standard EnsLib.HTTP.InboundAdapter.
When inspecting the message in the message viewer I expected to see a HTTPMessage XML in the Contents preview, but I found a GenericMessage with no HTTPHeaders section. After a while, I found out that the display in the message's Visual Trace differs from what is shown, when going to the View Full Contents view in the Contents tab of the message viewer.

Hello, I want to create PDF from HTML source. I found pandoc. I installed pandoc on IRIS container image. I created Interoperability production. I have setup REST service to receive HTML file in request body. I call pandoc command pandoc -o output.pdf input.html from a BPL process. I copy output.pdf file stream into response body. I save the response at the source. I get a file named output.pdf but it does not load in Acrobat. I suspect I am doing something wrong with headers (accept-encoding?) or maybe do I need to base64 encode the pdf file to transfer it via REST?
I am currently part of a team that is developing an application using Microsoft PowerApps as the front end and IRIS as the backend. Effectively that frontend screens, which are house and an Azure serve, call a series of REST interfaces exposed by IRIS from a physical Microsoft server. During the development stage we have not had any security in place but now we need to secure the application using a single sign on. PowerApps relies on Microsoft Entra for its security both LDAP and OAuth. Has anyone in the community connected IRIS to Microsoft Entra?
One of the most common kinds of integration we are asked to do is emailing. One of the most typical email services our customers use is Microsoft’s Office 365. After setting up the right configuration on the Microsoft side, we can email from IRIS with two HTTP requests.
I have a question about using OnInit() within a Ens.BusinessOperation.
When you include OnInit(), does OnInit() only execute when you start a Business Operation? Or does it execute OnInit () every time you send a REST request to the operation. I am trying to pinpoint when the best time is to execute the POST command to get the Token
I am needing to get a Bearer Token from a REST POST call and return the Authorization key prior to making the rest of the REST calls to pull down data.
I'm unable see the FHIR SQL builder /csp/fhirsql and /csp/fhirsql/api/ui endpoints in web application to access the FHIR SQL builder. I'm using community edition 2024.1 and it contains the "FHIR SQL Builder".
I'm testing a REST API that is used for our IRIS Backend with a mobile app (Angular / ionic).
The problem is that, our test environment does not yet have HTTPS capabilities, it's something we're going to set up ASAP, but right now we don't have it set up.
We want to test the API endpoints via a web browser using either a test application built in Angular, or the app itself built with NPM via the browser. This means that the set-cookie headers are being blocked by the browser.
I'd like to briefly announce three new packages, available on the Open Exchange / through ZPM, that can really help accelerate modern full-stack application development on IRIS. I announced all of these in a Global Summit session last week, but you may have missed it - and I hear there's a full-stack application development contest coming up!
I'm working with isc.rest and am going through the tutorial right now. My project directory exists on my IRIS server. When I try to create a module.xml file in the root package, I get a #16006 error. I see that there is a "generate" command for zpm that should create a module.xml for me on my local filesystem. How can I create this module.xml in the same folder that holds my code living on the IRIS server?
The Web Server Gateway Interface (WSGI) is a simple calling convention for web servers to forward requests to web applications or frameworks written in the Python programming language. WSGI is a Python standard described in detail in PEP 3333.
🤔 Ok, great definition and what the point with iris ?
