#API

GraphQL is a standard for declaring data structures and methods of data access that serves as a middleware layer between the client and the server. If you’ve never heard about GraphQL, here is a couple of useful online resources: here, here and here.

In this article, I will tell you how you can use GraphQL in your projects based on InterSystems technologies.

Just like the title says, I'm attempting to find a way to create a web application that instead of serving CSP files, it uses a dispatch class.
I searched for clues in the documentation, but the CSPApplication tag seems to be exclusively for CSP file-based applications.
I'm trying to avoid implementing a workaround such as using the Invoke tag to call the Security.Applications to generate the web application but I might be forced to do so, even though it's unpleasant if I had to say...
So, is there an official way to execute this task?

I'm looking into finding ways to  fetch data from cache efficiently and work with it with python - specially pandas.

i tried the following but i'm wondering if this is the most efficient way?

to run the stored procedure as %ResultSet inside cache in a classmethod and serialize the data to JSON

and then call that class method from python

Class User.RegObj Extends %RegisteredObject{ClassMethod runAlpha() As %Library.DynamicAbstractObject{set QHi=##class(%DynamicAbstractObject).%FromJSON("{}")set rs=##class(%ResultSet).%New("User.Person:alpha")set pr=rs.Execute("","")set idx=0w

Intro

For many in today's interoperability landscape, REST reigns supreme. With the overabundance of tools and approaches to REST API development, what tools do you choose and what do you need to plan for before writing any code? This article focuses on design patterns and considerations that allow you to build highly robust, adaptive, and consistent REST APIs. Viable approaches to challenges of CORS support and authentication management will be discussed, along with various tips and tricks and best tools for all stages of REST API development. Learn about the open-source REST APIs available for InterSystems IRIS Data Platform and how they tackle the challenge of ever-increasing API complexity. The article is a write-up for a recent webinar on the same topic.

I am writing an API that sends over a very large JSON object. 

The code I'm using to get the data is actually used in our production system today for the use of writing a report.

However when I call the code using the API (using SoapUI) I am getting 'Error getting response; java.net.SocketTimeoutException: Read timed out'

The web applications settings have a session timeout setting at 15 minutes, but this is timing out within just a few minutes, so I know it's not hitting this mark.

Has anyone experienced this issue with APIs?  We are used to spitting out a lot of data and quickly with Cac

Hello community,

I have a very simple REST API connection doing a POST of JSON messages via AZURE APIM. 

It worked successfully for few weeks until a day ago when i started receiving a bad response as below.

This quick guide shows how to serve HTTPS requests with InterSystems API Management. Advantage here is that you have your certs on one separated server and you don't need to configure each backend web-server separately.

Here's how:

1. Buy the domain name.

2. Adjust DNS records from your domain to the IAM IP address.

3. Generate HTTPS certificate and private key. I use Let's Encrypt - it's free.

4. Start IAM if you didn't already.

5. Send this request to IAM:

POST http://host:8001/certificates/
{
    "cert": "-----BEGIN CERTIFICATE-----...",
    "key": "-----BEGIN PRIVATE KEY-----..."

First webinar on  InterSystems API Management!

We are pleased to invite you to the upcoming webinar in Russian: Introduction to InterSystems API Management on November 21 at 10:00 Moscow time (GMT+3)!

As you might have heard, we recently introduced the InterSystems API Manager (IAM) - a new feature of the InterSystems IRIS Data Platform,
enabling you to monitor, control and govern traffic to and from web-based APIs within your IT infrastructure.

In this webinar I will highlight some of the many capabilities IAM allows you to leverage. InterSystems API Manager brings everything you need:

• to monitor your HTTP-based API traffic and understand who is using your APIs; what are your most popular APIs and which could require a rework.
• to control who is using your APIs and restrict usage in various ways. From simple access restrictions to throttling API traffic and fine-tuning request payloads, you have fine-grained control and can react quickly.
• to protect your APIs with central security mechanisms like OAuth2.0 or Key Token Authentication.
• to onboard third-party developers and provide them with a superb developer experience right from the start by providing a dedicated Developer Portal for their needs.
• to scale your API demands and deliver low-latency responses

There would be a live demo.

This webinar is for System Architects, Developers and DevOps Engineers.
Time: November 21 at 10:00 Moscow time (GMT+3)!

The language of the webinar is Russian.

Register!

SQL and Object Access

I have been trying to pass a %Global  character stream back on a Soap Response has anyone one out there done it before please help with guide lines on how to achieve this thanks in advance just some working sample code and will take it from there thanks again

Good morning -

I am attempting to pass some HL7 content (say, a complete ADT message) from one server to another via REST/JSON - for reasons. 

I can get the data across but when I try to create an EnsLib.HL7.Message object from the message in the JSON body, I end up with just the start of an HL7 msg in the resulting object. Looks like: MSH|^~\&

The start of the code accepting the data looks like this:

S tReq = {}.%FromJSON(%request.Content.Read())
S tInput = tReq.Message

S tMsg = ##class(EnsLib.HL7.Message).%New()
D tMsg.ImportFromString(tInput)
S tMsg.DocType = "2.3.1:ADT_A01"

So now if I

I am trying to return a stream soap response using web services I can call my web service supply it with a xml string which works fine . I then work on that XML and try to return  a Stream but all works in the production when my service receives the stream after I get the error  as if its trying to copy stream to a variable and I am confused as to where that operation happens.

The errors I am getting 
ERROR <Ens>ErrException: <METHOD DOES NOT EXIST>zCopyFrom+28^%Stream.TmpCharacter.1 *Rewind

and here is the stack trace in case I am missing something

• $$^zGetErrorTrace+3^Ens.Util.Trace.1 +1

I am still working on a generic task where I need to apply journal file records to another database. Initially I didn't want to use Journal.Restore class methods as I need to perform some data transformation, and it seemed that the clearest way to achieve it was to read journal file record by record using %SYS.Journal.Record API. 

This approach worked (with some help from @Dmitry Maslennikov and @Eduard Lebedyuk), while it turned that the processing speed of %SYS.Journal.Record:List query was very slow, about 1MB of journal data per second on a mid-range server.

Therefore my second try was t

Hi There ,

     We are trying to do a small POC trying to integrate NHS Careconnect with Ensemble/Healthconnect. Does anyone have implemented this before. It would be good that you provide some suggestions  or any sample implementation. It would be good to get suggestions any  interesting use cases 

within NHS England for the POC.

Good afternoon - I am in the process of writing a AngularJS front-end for some CoS functions that my integration team uses for auditing, analyzing and various other purposes. I have re-tooled the functions to return JSON results that AngularJS can then interpret and display. Many kudos to the AngularJS series on this site for giving me a jump start.

One of these functions uses %SQL.Statement to prepare a class query on %Dictionary.CompiledClassQuery, Summary. This works perfectly if I give the web app making the call %All privileges but obviously I don't want to do that. I cannot determine the
