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.
I already talked about GraphQL and the ways of using it in this article. Now I am going to tell you about the tasks I was facing and the results that I managed to achieve in the process of implementing GraphQL for InterSystems platforms.

Generation of an AST for a GraphQL request and its validation
are you curious which topics we are going to cover at this year’s Global Summit? You have come to the right place! I will provide you with a sneak peek of what you can expect from the areas I am responsible for.
I'm getting mad trying to get data from an external REST service that uses Basic Authentication from Ensemble. The BO worked fine when I was using a test server without authentification, but as soon as we need to go to production I cannot have it working.
So far, I've created the username/password at the credentials page (Ensemble-Configure-Credentials). I've setup the BO to use this credentials. But nothing happens.
I've tried with the Rest Client (addon for Mozilla), and using the same address, port and user/pwd works just fine.
The REST webservice works perfectly when run on SOAP UI. This end point server is an https site that uses basic authentication (uname and pwd). But when I run the request through an Enslib.Rest.Operation using a configured SSL and stored credentials, I get an "unauthorized" error, unless I explicitly hard code the password in the operation class. HS Version is 2014.1 .
I have 2 questions. Pardon me, they are both related!!
I'm trying to have my REST service return the entire data set for one of our legacy globals. Currently I am parsing the object from a SQL statement into generic objects to be returned like this:
I have a CSP REST web application where I'm using delegated authentication via basic authentication in the REST calls. When I do a call to the web app with correct user credentials, I get a CSPSESSIONID cookie back representing the CSP session, which has started for the user I'm logged in with.
And when I want to log out/end the CSP session with the "CacheLogout=end" query parameter, I get a 401 Unauthorized code back. But the csp session itself does get terminated, which means the logout call was successful.

Hi, Trying to work with REST protocol, using IIS 8, both client and server are Cache servers, I have the following problem- When I send a PUT command, I get the following error: <HTML><HEAD><TITLE>Length Required</TITLE> <META HTTP-EQUIV="Content-Type" Content="text/html; charset=us-ascii"></HEAD> <BODY><h2>Length Required</h2> <hr><p>HTTP Error 411. The request must be chunked or have a content length.</p> </BODY></HTML>
Does developing a RESTful API in Caché remove the requirement to use the InterSystems.Data.CacheClient.dll and generate proxy classes using the Caché Object Binding Wizard for .NET web development? If anyone has links to sample applications using .NET with Caché and REST Services, I would be grateful if you could share them.
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?
I'm experimenting with sending large amounts of data in a POST payload to be stored as a stream. However I've noticed that no matter how many characters are in the message, Cache only gets about 32k of them, cutting off the rest. Conversely as expected it can only send about 32k worth of characters in a payload.
Before I get creative, is there a REST message size limit that can be changed? Or is there something else going on here?
Hi.. I have an issue where we are using OAuth2.0 with the ZAUTHENTICATE routine. Once our token is validated we are using a users lan id (passed on the ID token) to find a software defined username in a Cache Global.
That is all working fine in ZAUTHENTICATE.. I am setting the software defined username in the Properties("Comment") array and wanting to reference it in the Rest Service Dispatch class.
I'm sending data via ajax to my REST service, and while retrieving any information sent in the url parameter is easy when they're defined in the route, I can't get anything if I store information in the data parameter. For example:
$.ajax({
url: "ServerURL",
data: { "some": "json" } //How do I get this information?
...
I've looked at many common solutions such as here:
I created new web application from Web Applications section in Management Portal. Such as screenshot. In browser call http://127.0.0.1:57772/rest/test . But got "Service Unavailable" 503 response. Could you please help?
I am trying to write an application that will take some information on the database make a call to the Google API distance matrix and get the information to use with rest of the application without using the ensemble part of the development is this possible and how can I do my communication with the API from a cache class thanks in advance
I'm in the process of creating a TestClass which simulate a HTTP POST call to REST-based web
services and while I am having success, I'm struggling on how to parse out the results to a JSON
format
Here is down the code part which concerns parsing the HttpResponse.Data variable into JSON :
