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.

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.

When using the REST API classes for building services on a spec-first approach, the implementation class methods are usually built this format:

ClassMethod <method-name>(body As %DynamicObject) As %Stream.Object

But sometimes it keeps building the endpoint implementation method like this:

ClassMethod <method-name>(body As %Stream.Object) As %DynamicObject

It has been a problem because the rest of my implementation rely on the fact that the "body" object is a DynamicObject.

I am trying to find out if it is possible to decode the Azure access token in IRIS. Has anyone ever tried this before? I need to decode the token to extract the "Scope" details in order to verify the scope to make sure client is permitted to do the request they have done.

If you could point me to any information, that'd be great. 

Thank you.

Hi All,
I am implementing REST API's in IRIS using the below link as a guide. 
I chose this approach so i could have a single entry point for requests regardless of namespace 

a sample form the HIHLib.REST.Server class i am using is below. my question is does IRIS and CSP cache responses for requests to the CSP.REST class?
and if so what parameters or properties do i need to enable?

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.

I have a vendor that is sending an HL7 message. But when I asked for more detail about their mapping tables, they told me they typically don't supply that but supply an API for customers to call so they don't have to define tables and it is more dynamic.

So with that being said I am creating my first REST operation. I understand the gist of how a REST operation works in working with other types out Non HL7 Operations (SOAP, SQL) before. You send a request and get a response back, that part I understand.

Hi All,

I hope someone can help me with the following, it's about the usage of the class EnsLib.HL7.Service.HTTPService.

Working situation right know.

In IIS we've got a site configured who is dealing with the client certificate, etc and redirect the full request to http://localhost/csp/healthshare/NAMEPSACE/EnsLib.HL7.Service.HTTPServic... and the web gateway redirects the request to Business Service 'EnsLib.HL7.Service.HTTPService.cls'.

FIrst of all thank you for your time in reading this question and writing a response,

We would need some help,

-> Our objective is to control which method is being used in the service: GET POST PUT

We have tried to understand the example REST Service: Demo.REST.DirectoryService


After that we have tried to create our own custom rest service,

please take a few minutes to examine the following code:
