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:

Hi Community,

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?

I'm running the image "containers.intersystems.com/intersystems/irishealth-community:2025.1" as a container on my local Docker desktop.

Now I want to set up an ODBC SQL connection, but I don't know how to do it.

I have tried various ways without success. Like building my own image (see "Dockerfile" description below).

I have also added ODBCINI variable in my docker-compse (see "Docker-compose.yml" description below).

Anyone done this before?

I'd really appreciate some help.

Thanks.

This article describes a significant enhancement of how InterSystems IRIS deals with table statistics, a crucial element for IRIS SQL processing, in the 2025.2 release. We'll start with a brief refresher on what table statistics are, how they are used, and why we needed this enhancement. Then, we'll dive into the details of the new infrastructure for collecting and saving table statistics, after which we'll zoom in onto what the change means in practice for your applications. We'll end with a few additional notes on patterns enabled by the new model, and look forward to the follow-on phases of this initial delivery.

I'm working with a CSP legacy system.

Is there a link we can use to invite other devs to ( so we can get credit for brining them in?)

Overview

This release introduces significant enhancements to security, analytics capabilities, and user experience, along with important operational improvements aimed at reducing downtime and improving reliability.

I'm trying to open a TCP connection to a remote system. The Caché command I'm using to open the connection is OPEN "|TCP|"_PORT:(IP::"PSE"):10 where PORT is a port number in the range 40000 to 40100 and IP is a standard IPv4 addess like 10.200.100.50
the connection appears to open because $TEST becomes 1.
I'm then writing to the open port with USE "|TCP|"_PORT:(::"S") WRITE "some text",*-3
It's a windows system

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!

Here is the result of my own exercise - a 100% prompted UI vs IRIS REST API that allows to list, create, update delete entries of a persistent class (Open Exchange, frontend source, video):

What is the recipe in detail?

Hi Community,

While writing an article yesterday, I realized I was so busy with people who came to the Developer Community table at the Tech Exchange that I forgot to take photos for you. Luckily, I realized the error of my ways and corrected my behavior accordingly 😉

So, let's look at what happened on Tuesday at the InterSystems Ready 2025! It began with a speech of Scott Gnau about the approach and architecture of InterSystems Data Platform and how it is different from all other DBMSs:

I am attempting to follow the tutorial at Publishing Web Services Using Caché | Caché Web Services QuickStart Tutorial | Caché & Ensemble 2018.1.4 – 2018.1.11 to build a toy SOAP web-service using Cache but am running into what I suspect are permissions issues, or perhaps setting up the "plumbing" to get an incoming request to call the web-service methods.

My HL7 message got "AR" (rejected ack code) and went to the suspended queue. I re-submitted it (without editing it) but forgot to write down the details before doing so. It got "AA" and everything works fine from there.

Now (the next day) I want to check with the downstream system why they returned "AR" initially. Is there a way to search for the original message the got an "AR", along with any returned error message please?

Thanks

Hi all,

We're developing a medical appointment app that connects doctors' schedules to an appointment provider.

The provider is returning us the appointment in the following format:

Thu Jul 03 08:20:00 CEST 2025

It means, 03 july 2025 at 08:20:00 Central European Summer Time (UTC+2)

But we need the following format:

2025-07-03 08:20:00+02:00

Is there any option to convert zone time code (CEST) to a UTC+x ?

How to convert zone time code (CEST, CET, ET, EDT, etc..) in its zone time in UTC (UTC+2, UTC+1, UTC-5, etc..) ?
