#REST API

I work as an Integration Engineer for United States Department of Veterans Affairs (VA). I work on a Health Connect production which processes many RecordMap files. I do not fully understand RecordMaps and I wanted to develop an application for the Interoperability contest where I could learn more about working with RecordMaps. I browsed InterSystems documentation for inspiration on how to start. I was happy to find CSV Record Wizard.

The first installment of this article series discussed how to read a big chunk of data from the raw body of an HTTP POST method and save it to a database as a stream property of a class. The second installment discussed how to send files and their names wrapped in a JSON format.

Now let’s look closer at the idea of sending large files in parts to the server. There are several approaches we can use to do this. This article discusses using the Transfer-Encoding header to indicate chunked transfer. The HTTP/1.1 specification introduced the Transfer-Encoding header, and the RFC 7230 section 4.1 described it, but it’s absent from the HTTP/2 specification.

Hello All,

I am just wondering if there is any inbuilt function or utility available in IRIS to clean up "null" elements from JSON e.g. I want to remove "null" elements from payload below before I do any processing with it.

{

recipients: [

{ "name":"Utsavi", "email":"utsavi@gmail.com"},

{ "name":"Utsavi 1", "email":"utsavi1@gmail.com"},

null, null

],

content:[null, {"title":"Test.pdf", "data":"ygwehfbnwfbhew"} ]

}

Thanks & Regards,

Healthcare interoperability is instrumental in improving patient care, decreasing healthcare provider costs, and providing a more accurate picture to providers. However, with so many different systems, data is formatted in many different ways. There are many standards that have been created to try to solve this problem, including HL7v2, HL7v3, and CDA but each one has its drawbacks.

I'm building a Flutter app for smartphones and with same code a Flutter web app.

Both are using IRIS with a RestAPI.

As described in your documentation

I added

pResponse.%JSONImport(tHttpResponse.Data) failing when we have mulitple (array) json objects in response.

I have an interoperability production that functions as a FHIR proxy. I have a need to add an HTTP Header value to the outbound request. I've subclassed HS.FHIRServer.Interop.HTTPOperation, but I cannot find a way to add an HTTP Header to the request. The HTTP class used in HS.FHIRServer.Interop.HTTPOperation is HS.FHIRServer.RestClient.HTTP. That RestClient class does not seem to expose or allow modification of the actual HttpRequest.

I am using MDX2JSON do display data, it uses CSP REST to retrieve data and uses Password Authentication. I enabled LDAP authentication for this applicaiton, but it does not work.

Hello Everyone,

We are currently in process of implementing REST APIs using IRIS and we are also looking at using Intersystems API Manager.

Our aim is to implement a Microservices Architechture where Services are small in size, bounded by contexts, autonomously developed, and independently deployable.

We are following a spec first approach where we are first defining the API specs into Swagger Hub and using IRIS API Management Service to build the REST classes i.e. the Specification class, Dispatch class and Implementation Class.

Hello,

I am trying to figure out if we can extend a business process in IRIS. My Use Case is that I am developing RESTful Interfaces and my each REST Interface needs to go through certain processes before getting to the actual action.

e.g. I have 2 REST Interfaces, GetPatient and GetEncounter. Both of these need to invoke "GetToken" Business Operation to go to the Authentication server to get an authentication token before they go ahead and hit the Business Operation to Get the data i.e. Patient or Encounter.

I'm trying to setup a REST server with CORS support. I have created a class that handles a specific part of the service (printer control). This class I have referenced in my main REST class by adding <Map Prefix="/print" Forward="myClass.PrintAPI" />

My main class does have its own <Route>s and handles CORS requests perfectly. But in my subclass OnHandleCorsRequest() is only run when requesting from same origin and never run when making a CORS request. I have set Parameter HandleCorsRequest = "true" in both my main REST class and the subclass.

@José Pereira and I created a good project, and we want to introduce a few words about this project to you.

What is IRIS RAD Studio?

IRIS RAD Studio is our idea of a low-code solution to show what's possible, to make the developer's life easier.

This article is a continuation of this post.

In the previous article, we discussed the development of business processes, which are part of the components required for system integration and serve as a production coordinator.

Bulid REST API application built with ObjectScript in InterSystems IRIS. It also has OPEN API spec, can be developed with Docker and VSCode, can be deployed as ZPM module. can be used as Overbooking System data REST api.
