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.
RESTful API Call From Cache to Particle.io Electron
Tom Fitzgibbon | Multidata | 212-967-6700 x537 | tom@mul.com
Summary: Simple Blink Tutorial for Particle.io Electron Device from Cache
Electron device is a tiny ARM processor ($40-$60) that connects to Particle’s world wide leased 2G/3G network (about $3/mo) and runs off an included LiPo battery. Using Cache’s %Net.HttpRequest you can send/receive data, control hardware and read sensors.
I just want to share with you the knowledge aka experience which could save you a few hours someday.
If you are building REST API with IRIS which contains more than 1 level of "/", e.g. '/patients/all' don't forget to add parameter 'recurse=1' into your deployment script in %Installer, otherwise all the second and higher entries won't work. And all the entries of level=1 will work.
/patients
- will work, but
/patients/all
- won't.
Here is an example of CSPApplicatoin section which fix the issue and which you may want to use in your %Installer class:
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.
QEWD is assumed by most people to only integrate with IRIS (or Cache) via a connection through IRIS's high-performance C interface. This requires QEWD (and its Node.js environment) to be installed and configured on the same machine as IRIS.
I'm frequently asked if QEWD can run on a separate server (or servers), and access IRIS (or Cache) over a network connection. The answer is yes it can, but the information on how to set it up in this way has been admittedly a bit tricky to discover.
Cross-origin Resource Sharing (CORS) is one of the basic security features built into browsers. CORS controls accessing resources from a HTML page in domains other than the original domain. It is particularly important for AJAX calls. Since RESTful services can be used as data provider to any AJAX call, you have to be able to control cross-origin access. By default services are not allowed to do CORS. You are going to learn how to enable it for Ensemble RESTful services.
At the end of our last lesson, we ended with our page displaying a nice (but garish) Angular Material Toolbar, and our Widget data displaying in a list of Material cards. Our page feels a bit static, and we already know that the large number of Widgets that we will be dealing with will not be especially usable on a static list. What can we do to help?
In the first installment of this article series, we 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. Now let’s look at how to save such data and metadata in JSON format.
The article is a step by step guide for beginners to learn how to build a RESTful web service consumer (or client) in Ensemble. The provider can be any RESTful service, but the example is based on the service we made during the previous sessions.
a.k.a.. "The World of Widgets Returns!" or "Paternity leave damages Instructional Series momentum"
In our last lesson, we combined 2 separate classes to appear as the same property. We now have the ability to Update our Widget catalog, but what if we want to Create a Widget? Thankfully, we've already done 90% of what we need, just by implementing Edits
Hi Community!
Today I'd like to share with you a link to some exercises from a workshop about developing REST APIs and how to manage them using InterSystems API Manager.
Presenter: Danny Wijnschenk Task: Build a development stack that enables state-of-the-art rapid development with a stable but adaptive back end. Approach: Use InterSystems’ new document data model to achieve modern full-stack development
The MEAN stack is a very popular stack for building applications quickly that can change at a rapid pace. We will explore the benefits of such a stack and how you can tackle the requirements for modern and fast paced front-end development with support of a stable, but yet adaptive back-end using our new document data model.

This article gives a brief introduction how a RESTful service consumer and a RESTful service provider exchange data. It is a beginner’s guide. Data is transferred from a consumer to a provider as parameters of the service. Parameters are part of a service request. The result of the service action a response is returned from a provider to a consumer. Both the service request and response are standard HTTP messages. Since HTTP is a flexible standard regarding to the message contents, RESTful services also enjoy the versatility of data transfer methods.
Hello again and welcome to the next tutorial on this series: Part 5 - Errors. Here we are going to learn how Frontier handles unexpected errors and how we can force them.
Presenter: André Cerri Task: Use third-party visualization tools to present your DeepSee data Approach: Use DeepSee REST services to access DeepSee data from third-party tools
Come see examples of how you can use popular 3rd party data visualization tools to access your DeepSee data.

Hello again! Welcome to the Part 2 - Handling payloads!
If you're new to this series, I'd recommend you to check out the Part 1 - Core concepts. You'll need a basic understanding about how Frontier works before continuing with the Part 2.
