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.
When I was younger (a question about exactly how much younger is outside the scope of this article), the word “token” meant fun. You see, just a couple of times a year, I would get to go to an arcade and play some amusing video games with my friends.
Hello, I am currently facing the task of retrieving or sending HL7 messages from a web API. Since we only send HL7 messages via internal sockets, web APIs are relatively new to me. The following is my plan for the new interface:
This is a quick tip about how to use case insensitive URL in REST API.
If you have a class that extends from %CSP.REST and Ens.BusinessService, to create a REST API service, and you have defined your WebApplication in lowercase
Can I please check if anyone has built a simple web interface for maintaining custom SQL lookup class.
We have a simple persistent class in HealthShare which is used for storing Pathology test codes. Test codes in this lookup class is used for message filtering and applying additional logic when processing pathology results/orders.
Managing IAM can be tedious when done manually — especially when your APIs are already well-documented using OpenAPI (Swagger) specs. Wouldn't it be great if you could automatically generate Kong services and routes directly from your OpenAPI spec?
That's exactly what this ObjectScript method does: it reads an OpenAPI 2.0 spec stored in the XData block of your spec class and generates a decK-compatible YAML file that can be used to sync your IAM configuration.
Securing IRIS Integrations with Mutual TLS (mTLS): A Practical Guide
In today’s enterprise environments, secure communication between systems is not optional—it’s essential. Whether you're integrating InterSystems IRIS with cloud APIs, internal microservices, or third-party platforms, Mutual TLS (mTLS) offers a powerful way to ensure both ends of the connection are authenticated and encrypted.
This post walks through how to configure IRIS for mTLS and how to validate your certificates to avoid common pitfalls.
One of the recommendations when deploying InterSystems Technologies for production is to set up High Availability. The recommended API Manager for these InterSystems Technologies is the InterSystems API Manager (IAM). IAM (essentially Kong Gateway) has multiple deployment topologies.
A FHIR Server is a software application that implements the FHIR (Fast Healthcare Interoperability Resources) standard, enabling healthcare systems to store, access, exchange, and manage healthcare data in a standardized manner.
Intersystems IRIS can store and retrieve the following FHIR resources:
Resource Repository – IRIS Native FHIR server can effortlessly store the FHIR bundles/resources directly in the FHIR repository.
FHIR Facade - the FHIR facade layer is a software architecture pattern used to expose a FHIR-compliant API on top of an existing one (often non-FHIR). It also streamlines the healthcare data system, including an electronic health record (EHR), legacy database, or HL7 v2 message store, without requiring the migration of all data into a FHIR-native system.
What is FHIR?
Fast Healthcare Interoperability Resources (FHIR) is a standardized framework created by HL7 International to facilitate the exchange of healthcare data in a flexible, developer-friendly, and modern way. It leverages contemporary web technologies to ensure seamless integration and communication across various healthcare systems.
I have a request from a client who wants to do the following. Currently, they have a data upload process via FTP in which they have implemented a RecordMap to store the information of the CSV files that are uploaded to the FTP directory. Now they want to have another directory so that it is ONLY executed through an external instruction, not when the file is uploaded to the directory.
I’ve been exploring options for connecting Google Cloud Pub/Sub with InterSystems IRIS/HealthShare, but I noticed that IRIS doesn’t seem to ship with any native inbound/outbound adapters for Pub/Sub. Out of the box, IRIS offers adapters for technologies like Kafka, HTTP, FTP, and JDBC, which are great for many use cases, but Pub/Sub appears to be missing from the list.
I’m working with an existing InterSystems IRIS server that hosts several web applications and namespace-specific code and data. I’d like to reverse-engineer the current environment into a %Installer.Manifest file so I can store it in Git and manage its changes.
I would like to ask whether it is possible to run InterSystems API manager (IAM) on OpenShift. Is there some documentation describing how to do it? I was searching the forum as well as the internet and I have not found much unfortunately.
In this section, we will explore how to use Python as the primary language in IRIS, allowing you to write your application logic in Python while still leveraging the power of IRIS.
REST API (Representational State Transfer Application Programming Interface) is a standardized way for web applications to communicate with each other using HTTP methods like GET, POST, PUT, DELETE, etc. It's designed around resources, which can be anything from a user to a file.
Dear community, I have a confession to make. I have not gotten over Zen yet. Alas, all good things must come to an EOF, so I am currently learning about Angular. I am working on proving to myself that with the right back end and Angular components, I can deliver to myself and my team a very Zen-like experience in this environment.
Is there a programmatic method or specific property to differentiate system-defined (/csp/altelier , /api/mgmnt and so on) or user-defined web applications in IRIS?
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?
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 few weeks ago I published an API accelerator call Memoria, Is a very simple way to minimize the time and network traffic to and end-point, I hope could be useful.
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:
Google Forms is the most popular solution on the market for collecting data, answering questionnaires and quizzes. So, it is the ideal solution for collecting patient data and responses in a practical way, without the need to expand or develop systems. In this article, I will detail how to create an account on Google Cloud, register the application that will consume the Google Forms API, generate the service user necessary to consume the API and finally perform actions to create new forms and collect data filled in them in an automated way in embedded Python and IRIS.
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 was wondering if it was possible to use something like EnsLib.SQL.InboundAdapter with tables in IRIS.
This library monitors when a record has been inserted into a table in an external database, so it requires a DSN to connect to that database.
My goal is to make a call to an external API that takes a long time, it could spend nearly an hour (or more) completing its processes, but I don't want to block the main process.
