![]() Statelessness: the communication should have no client context stored on server.Client-Server Architecture: the user interface of the website/app should be separated from the data request/storage, so each part can be scaled individually.There are a few constraints on the definition of REST: REST is basically a set of rules for communication between a client and server. Let's demystify what that means (hopefully you got the full form). 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 So, what is REST? According to Wikipedia: Representational state transfer ( REST) is a software architectural style that defines a set of constraints to be used for creating Web services. Let's dive a bit deeper into JavaScript! Get that jargon away We'll declassify some of the jargon and have a look at how we can code a server in NodeJS. In this beginner friendly guide, I will walk you through the process of setting up a RESTful API. MyTestDistrict has been deleted.Ever wondered how login/signup on a website works on the back-end? Or how when you search for "cute kitties" on YouTube, you get a bunch of results and are able to stream off of a remote machine? In the Service Edge UI, refresh the Business Hierarchy view. The response message is an HTTP 204 No Content code. Remove the HTTP body, which is not relevant for the DELETE method. Substitute the Key value that the POST method returned in step 6. Run the HTTP DELETE method on the following URL. Now use Postman to delete MyTestDistrict. You might have to refresh the browser to display it. You can see MyTestDistrict in the Business Hierarchy view of the Service Edge UI. In a moment, you will use it to delete the object. In the RegionParent property, substitute a region name that exists in your -1,Īfter a moment, the bottom area of the Postman windows displays the REST response. On the Body tab, select the following options:Ĭlick this option and select JSON (application/json).Įnter the body of the r equest. Select the Basic Auth option (basic authentication).Įnter the integration user name of your Service Edge tenant, such as (substitute your tenant name).Įnter the password of the integration user. Then click the Update Request button to save your entries. On the Authorization tab, enter the following options.Select the POST method that we want to test.Įnter the URL of the REST service (substitute your host name): HTTP method (at the left end of the toolbar).On the toolbar of the Postman window, enter the following options:.If prompted, log on to your Google account and supply a unique user name that you will use with Postman.Browse to the Postman app on the Google Web Store, click Add to install Postman, and click Launch to start it.We will then run the DELETE method of the Object service, deleting MyTestDistrict. We will run the POST method of the Object service, creating a new item called MyTestDistrict in the District dictionary. The following procedure illustrates the use of Postman to test REST methods. You can test any REST method, such as GET, POST, or DELETE, by installing one of the following free add-ons for the Google Chrome browser: PostmanĪvailable in the Google Web Store at. If the browser prompts for an application in which to display the REST response, select a text editor such as Notepad. After a moment, it displays the REST response. The browser sends the request to the Service Edge server. For example, if the URL of the Service Edge UI is, enter the following URL: You can do this in the same or another browser tab. ![]() In the URL text box of the browser, enter the URL of the GET request.Log on to the Service Edge as a user who has the implementer role.» To test the GET method of a REST service: This example is the GET method of the Objects server, retrieving the items in the District dictionary. You can do this in the ways outlined on this page. As you develop a REST API application, you might want to test the REST request syntax or obtain a sample of the REST response syntax.
