#REST API

10 Followers · 631 Posts

Representational state transfer (REST) is a software architectural style that defines a set of constraints to be used for creating Web services. Web services that conform to the REST architectural style, called RESTful Web services (RWS), provide interoperability between computer systems on the Internet. RESTful Web services allow the requesting systems to access and manipulate textual representations of Web resources by using a uniform and predefined set of stateless operations. Other kinds of Web services, such as SOAP Web services, expose their own arbitrary sets of operations.

With Intersystems indicating ZEN pages are being deprecated, I'm looking to find out how to add custom configuration pages for the management portal using the new method similar to the new Rules editor.

From what I can tell the new method uses rest pages using JWT Authentication, and has a mechanism to use the session cookie to generate the JWT token.

While working with GET request I encountered this situation where FHIR Server return a responseStatusHTTP "HTTP/1.1 200 200" instead of "HTTP/1.1 200 OK" (as highlighted in the attached screenshot).

Although the response code seems valid, these bundles have a total value of 0.

Could anyone clarify what "200 200" signifies in this context? Is there an issue with my setup, or does this indicate a specific condition related to the empty bundle search?

Thank you in advance for your help!

We've got some web services that utilise EnsLib.SOAP.Service/EnsLib.REST.Service. These do some further requests to a few operations to call some other services and return the combined results.

An issue that we are noticing is that some of the usage involves users hitting the refresh button a few too many times and generating a lot of requests. This is mostly an issue when the service that the operations are calling are down or slow to respond. IRIS starts using a lot of RAM when this occurs and has caused outages by getting through an extra 50-60GB of RAM.

Hey,

I'm testing a REST API that is used for our IRIS Backend with a mobile app (Angular / ionic). 

The problem is that, our test environment does not yet have HTTPS capabilities, it's something we're going to set up ASAP, but right now we don't have it set up. 

We want to test the API endpoints via a web browser using either a test application built in Angular, or the app itself built with NPM via the browser. This means that the set-cookie headers are being blocked by the browser. 

Is there a way that we can allow the set-cookie header to be set in the browser for testing?

Hello Community,

I've configured a FHIR Server in FHIR Configuration "/csp/healthshare/learn1/fhir/r4 " and I enabled a JWT Authentication for this web application. I've invoked this url http://localhost:52773/csp/healthshare/learn1/fhir/r4/login with basic auth get the JWT token. Now I use the access token as a "Bearer" for GET the patient resource. But I got 401Unauthorized error. Anyway I can get the patient resource with basic auth. I tired assign with %ALL role for testing as well. Did I miss any additional configuration in "FHIR Server Configuration"

Up until recently, I have been toying around with REST/FHIR capabilities but only internally. Now I have a request to make REST API calls outside of our Network. 

I am using an RSA 4096 key, because Microsoft Active Directory Services which generates the signed certificate could not handle the Elliptical Key (ECC) when I put the request in.

  • Others in the Healthcare industry, how have you handled this when there isn't an API manager involved?
  • Do you connect directly through the Interoperability Engine using a TLS key?

I am trying to create my first call to our Epic FHIR Repository from Health Connect using Samples-FHIRStarter now that I have OAuth2.0 connection tested/working with our Epic Interconnect URL.

When I take a patient example from our Epic environment and test it through Data.BPL.PatientRecordCollector within the Namespace, I keep getting a 404 - File or directory not found 

as it tells me it cannot find the patient. So, I know the connection is being established, I just can't see what is being sent to Epic to see if I could test it through Postman.

Hello Community,

Is there any way to avoid generating the built in validation inside the classmethod from the .disp class definition. I've added the resource with path parameter as integer in swagger 2.0 open API.  The class method(in my case getRandom is the class method) inside .disp handles the integer validation by default. Is there a way to avoid/remove by default.

default validations for Integer

If ($number(pmin,"I",-2147483648,2147483647)="") Do ##class(%REST.Impl).%ReportRESTError(.

Hello,

First of all thanks for your time, thoughts, teaching and help:

We wonder how could we get the metrics from http://[Ip]:[Port]/api/monitor/metrics and use them in Kibana to chart statistics.

We would like to ask you how do you use the api monitor metrics, and as a second question, how would you suggest to utilize them in a third party software as Kibana to chart them.
 

We have thought to do the following:

1. Retrieve Metrics from Intersystems HealthShare API: Use a tool or script to make requests to the Intersystems HealthShare REST API and obtain the list of metrics.

Hello Community,

I've enabled the JWT Authentication in my web application. I invoked the /login page to get the JWT and it creates an entry in %SYS.TokenAuth table. Is there any time span for the entries will rid out from the table automatically or It's  a manual process? Where can I find the JWT signature private/public key

Question Eduard Lebedyuk · Jul 20, 2023

I have the following setup: REST broker calls inProc BO via BS. As BO initialization is time-consuming, I want to reuse the same BO during the CSP process lifetime.

I have tried the following approaches:

  1. Set %session.Preserve to 1 (I would prefer not to use it as the BO object is not linked to a specific client)
  2. Set $$$EnsInProcPersist to 1 (looked relevant)
  3. Cached BS between calls

However, every time I call my REST endpoint, I get a new BO. Is there a way to cache inProc BOs in the CSP context?

To run the sample, import it into any interoperability-enabled namespace, start in.

Hi guys,

has anyone done a simple angular searchbar with a REST API on Caché in the back?

I've done this Let's write an Angular 1.x app with a Caché REST backend here in the community and it

works fine for me.

The REST in Caché is already developed but im hanging at the searchbar in Angular, don't know how to solve this.

Has somebody an example to help me out?

Any help would be appreciated.
