With decoupled development getting the ground, it has become important for the developers to understand the REST technology better. It is based on representational state transfer (REST) technology, an architectural style, and approach to communications often used in web services development. This can be made possible by using HTTP requests to GET, PUT, POST and DELETE data. These are particularly used for creating APIs for clients spread across the web.Dear Developers, in this article we will discuss about, how to create RESTful web services in Drupal 8 | 9. RESTful web services are loosely coupled and are lightweight web services. It helps us to easily send and retrieve data between two or more different services using XML or JSON. So we have seen REST can be used as a type of data transfer which is built, based on the architecture of the HTTP protocols. Now go to “ /vb-rest?_format=json” and the URL will result in a Taxonomy term list containing Term ID and title. Enable the custom rest resource and do the following configuration. Search for our custom rest resource using the id that we have created in the resource file. Step 8: After enabling the custom module, enable custom rest resource.įor enabling custom rest resource, follow these steps:-Ģ. Step 7: Let’s enable our custom module now. The Rest UI module can be installed using this command: “composer require 'drupal/restui:^1.20'”Īfter installing the RestUI module, enable both the modules and follow the snapshots attached to configure REST API. Our module will be dependent upon the Rest and Rest UI module. Step 6: Now let's first enable Drupal REST API which is provided by core itself. Step 5: We have created a “Vb Test” taxonomy and added two terms in that. As an example- we require all the existing terms title with their respective IDs for “ vb (machine name of Vb Test)” taxonomy for currently logged user. We’re using the “ GET” method in the template, in which we define our logic in the form of code to define what output is required. For that, create a php file as “SampleGetRestResource.php” and place the file in the “resource” folder. Step 4: We will implement our resource file. The folder structure will look like this: Step 3: Create a folder structure in the custom module as “src\Plugin\rest\resource”. By GET method, we need to fetch the list of taxonomy term “ vb”. We are now moving forward towards implementation of a rest resource using the GET method. Now the folder structure will look like this: Step 2: Create an info.yml file as “sample_rest_” along with a blank module file as "sample_rest_resource.module" Step 1: Create a custom module in the “\web\modules\custom” folder. ![]() To learn how to create custom web services, we would create a custom module exposing RESTful API which can display a list of taxonomy terms from our Drupal 9 site. Here, it can be made possible by using several HTTP requests like POST (Create the data), GET (Retrieve/Read the data), DELETE (Delete the data) or PATCH/PUT (Update the data). While designing APIs, there is always a need to specify which HTTP method will be used for performing CRUD operations on data.
