Application Programming Interface (API) is a set of subroutine definitions, protocols, and tools for building application software. In general terms, it is a set of clearly defined methods of communication between various software components.
A concurrent session in IRIS: SQL, Objects, REST, and GraphQL
Kazimir Malevich, "Athletes" (1932)
"But of course you don't understand! How can a person who has always traveled in a horse-drawn carriage understand the feelings and impressions of the express traveler or the pilot in the air?"
Kazimir Malevich (1916)
Introduction
We’ve already addressed the topic of why object/type representation is superior to SQL for implementing subject area models. And those conclusions and facts are as true now as they have ever been. So why should we take a step back and discuss technologies that drag abstractions back to the global level, where they had been in the pre-object and pre-type era? Why should we encourage the use of spaghetti code, which results in bugs that are hard to track down, and which relies only on virtuoso developer skills?
There are several arguments in favor of transmitting data via SQL/REST/GraphQL-based APIs as opposed to representing them as types/objects:

I want to create a Sample Database for Cache InterSystems and want to access it via Cache Entity Framework Provider. But, I cannot find a particular engine of Management Portal to create a database.
Can you guide how to install Management Portal in Windows?
In this 3-part series of articles, is shown how you can use IAM to simply add security, according to OAuth 2.0 standards, to a previously unauthenticated service deployed in IRIS.
In the first part, was provided some OAuth 2.0 background together with some IRIS and IAM initial definitions and configurations in order to facilitate the understanding of the whole process of securing your services.

I have to create to a web socket client, but I'm unable to read any data from the server, after flushing the buffer. I have no access to the server, only two examples for the client, one in java and the other one in php:
java example:
socket = new Socket("192.168.0.1", 2003);
DataOutputStream out = new DataOutputStream(socket.getOutputStream());
out.writeUTF("aPassword");
out.writeInt(websiteId);
out.flush();
DataInputStream in = new DataInputStream(socket.getInputStream());
InterSystems API Management (IAM) - a new feature of the InterSystems IRIS Data Platform, enables you to monitor, control and govern traffic to and from web-based APIs within your IT infrastructure. In case you missed it, here is the link to the announcement. And here's an article explaining how to start working with IAM.
In this article, we would use InterSystems API Management to Load Balance an API.
In our case, we have 2 InterSystems IRIS instances with /api/atelier REST API that we want to publish for our clients.
There are many different reasons why we might want to do that, such as:
Load balancing to spread the workload across servers
Blue-green deployment: we have two servers, one "prod", other "dev" and we might want to switch between them
Canary deployment: we might publish the new version only on one server and move 1% of clients there
Hi Community!
Today I'd like to share with you a link to some exercises from a workshop about developing REST APIs and how to manage them using InterSystems API Manager.

In the context of IKO (Iris Kubernetes Operator) the question of Service not redirecting dynamically to the correct Pod is still pending. In production this can be dangerous since an overload (or any other simpler problem) can cause you to change the main Pod and leave the application inoperable until we intervene.
Intersystems support warned that this is still an issue of IKO, but there are some possibilities that I am studying.
To explore an idea I had, I would like the help of this Forum to answer the following question:
Following Issue: When I update a SQL table like (update OnlineV3Admin.ParameterApp set popuptext = '' where ID = '1') and then read it for my Json WebService there is a /"x00" in my Json.
What is the best option to disable that? I need here a empty String and not /x00.
I have a Problem with the Session Handling in .csp.
I wrote all my Web Services in .csp-Pages and do the work for example in the OnPreHttp Method for to get some data.
After that the Web Service response is in JSON.
I call These Web Services via fetch in my react Single Page application, also Many request parallel. The react App is Rolled out as index.html. Everything Works Fine with the session Handling via Cookie.
I've run into an issue where job IDs are being retained through multiple calls. My team is doing a rewrite of our system that allows VB6 apps and web apps to directly interact with our Cache databases.
The new process has those applications calling into a WebAPI which then calls into the routines.
The demo is based on the raw class descriptions. The data classes used are Address, Person, Employee, Company For a more attractive demo, a JSONtoString method by ID was added.
It seems to me that for some reason this didn't make its way to the official documentation and seems to be rather unknown though implemented already in IRIS 2020.1
Thanks to @Dan Pasco I got a hint on the classes involved. I used the recommended sequence of how to use it. it is all directly taken from Class Reference and I just collected it to create a first overview.
a HealthConnect customer of ours came across with a question to use an external service via REST and OpenID within one of his HealthConnect (2020.1) productions. The overal idea is to send data to the external system after receiving a baerer token to use for the communication between HealthConnect and this system.
Nowadays, there is a lot of applications that are using Open Authorization framework (OAuth) to access resources from all kinds of services in a secure, reliable and efficient manner. InterSystems IRIS is already compatible with OAuth 2.0 framework, in fact, there is a great article in the community regarding OAuth 2.0 and InterSystems IRIS in the following link here.
We have an immediate requirement for an experienced Intersystems Ensemble/Health Connect consultant to join our team with a good grounding in OO Programming, Healthcare Integration and at least 2 years experience with InterSystems Ensemble/Healthshare Health Connect
