#REST API

Integrating frontend React applications with backend services like IRIS database via REST APIs can be a powerful way to build robust web applications. However, one common hurdle developers often encounter is the Cross-Origin Resource Sharing (CORS) issue, which can prevent the frontend from accessing resources on the backend due to security restrictions enforced by web browsers. In this article, we'll explore how to tackle CORS issues when integrating React web apps with IRIS backend services.

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.

Context

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 ?

Introduction

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.

Description

This is a template for an Django application that can be deployed in IRIS as an native Web Application.

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 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.

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?

As part of the Open Exchange competition Salford Royal (Dean White and Mark O'Reilly) developed a REST API for sharepoint as a template that works but can also be a starting point to your own Rest Applications

Prerequisites

This is using the v1 REST sharepoint API you need a tennant id, client id, client secret and tennant name

Setup

Configure an OAuth server

The code in the middle is the tennant ID

Hello Community,

Is there any built in methods available to generate the both HTTP message format(request/response) from %Net.HttpRequest and it's response.

Thanks!

Hello Community,

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 am attempting to make a FHIR call against the Epic Repository through Intersystems. I have setup a Service client per Create FHIR REST Client | InterSystems Developer Community | Business

but I have set it up using OAuth and HTTPS.

I have verified that the OAuth works by executing it manually via a Terminal to verify I get a response. Of course, when I do it is writing to the ISCLOG

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.

Hi Community,

Watch this short exercise in writing basic code snippets in InterSystems ObjectScript using Copilot in VSCode and the GPT-4.0 engine. This screencast covers "Hello, World," global manipulation, class creation, and building a simple REST API application.
