The main four HTTP methods, and their meanings, are:įor example, creating a new book, should be represented by:Īnd the parameters to pass on that POST invocation should be the following JSON: įeni圎du™. Then, you can associate a particular HTTP method to each one of these paths, where each method has a particular meaning: These URIs are essentially paths, and can be contextual, like for example listing all the requisitions of a particular book: REST APIs are accessible through HTTP, therefore, it is necessary to identify the URIs and the respective methods where the resources they expose can be accessed. REST (representational state transfer) refers to a set of specific rules that dictate how web service applications communicate over the internet. Now that you identified all the necessary resources to expose, you need to identify their respective locations. Therefore, a RESTful API is an API that follows these rules, providing flexibility, bandwidth, and speed advantages to software integrations and communications. Step 2 - Define your endpoints and methods REST (representational state transfer) refers to a set of specific rules that dictate how web service applications communicate over the internet. These resources identify the data entities that your user interface will need to display to the user so that he can interact with the application and perform all the necessary use cases. Examples of resources that you might want to expose are: Let’s take for instance an application that manages a library. RESTful web services are loosely coupled, lightweight web services that are particularly well suited for creating APIs for clients spread out across the. Note that resources are not necessarilyĭomain entities, althought it may appear to be so. This service lets you acquire near real-time water data from thousands of sites managed or monitored by the USGS across the country. Available REST Web Services Instantaneous Values (IV) Web Service. For more details, please read this Wikipedia explanation. The first thing to do when building a REST API is to identify which resources will be exposed by your module. REST is a 'URL friendly' way to retrieve data (generally in an XML format) over the web.

In this tutorial you will learn how to identify and implement a set of REST endpoints that expose your module features through web-services. If your software module has a user interface that needs to consume a REST API, you should expose web-services from your module with a REST API. In this document, the REST web services functionality is demonstrated using the Postman Application. Expose your web-services with a REST API.
