Magento 2 Web APIs
Magento Web API is a key feature of Magento which supports developers to use web services that communicate with the Magento system. For instance, a developer can create a customer account, product record through web service.
Magento Web API framework includes the following features:
- It supports both REST (Representational State Transfer) and SOAP (Simple Object Access Protocol)
- Magento Web API requires authentication to perform any task. There are 3 types of authentication:
- Token-Based Authentication based on REST and SOAP
- Oauth-Based Authentication based on OAuth 1.0a
- Session-Based Authentication based on the current logged-in session of admin/customer
Here, in this article, to explain more about REST Web API.
CONSTRUCT A REQUEST:
There are many Web APIs in Magento and these are defined in webapi.xml file of a module that is <module root dir>/vendor/<vendor-name>/<module-name>/etc/webapi.xml, where <vendor-name> is vendor name (e.g. magento) and <module-name> is module name (e.g. module-customer). For example, the web API for the Customer service is defined in the <Magento dir>/vendor/magento/module-customer/etc/webapi.xml.
A Web API call has the following elements to perform an action:
- HTTP verb - The action to perform against the endpoint. There are:
- GET (default)
- PUT
- POST
- DELETE
- Endpoint - An endpoint is a combination of the server that fulfils a request, the web service, the store code, the resource against which the request is being made, and any template parameters.
To create the endpoint in the call -
https://<MAGENTO_HOST_OR_IP>/<MAGENTO_BASE_INSTALL_DIR>/rest/
For instance -
http://your-domain.com/index.php/rest/default/V1/customerGroups/:id
Here,
your-domain.com/index.php/ is the server name
rest is the name of web service
default is the code of default store of Magento Store. It can be a code of specific code or all can be specified to perform an action on all stores.
V1/customerGroups is the resource
id is a template parameter
- HTTP Headers – These are:
- Authorization: It is required and specifies the token for authentication.
- Accept: It is optional and specifies the format of response that is json (default) and xml.
- Content-Type: It is required if request body is specified. Format of request body can either be json or xml
- Call Payload – It is a set of input parameters and attributes that is supplied with the request. This is a request body in either json or xml format.
REST Web API are run through cURL. CURL is a command-line tool that lets you transmit and receive HTTP requests and responses from the command line or a shell script.
To make a Web API call, it requires an authenticated token for the cURL requests for admin and customer. To get a token, following are the REST URLs:
- Admin Token - POST /V1/integration/admin/token
- Customer Token - POST /V1/integration/customer/token
Following is the code to retrieve a token for admin -
<?php
$adminData = array("username" => "admin", "password" => "admin@1234");
$ch = curl_init("http://your-domain.com/index.php/rest/V1/integration/admin/token");
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($userData));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/json", "Content-Length: " . strlen(json_encode($adminData))));
$token = curl_exec($ch);
curl_close($ch);
This code will assign Admin Token to $token variable.
Now, following is the code to create a new customer account:
<?php
/*********CREATE A CUSTOMER ACCOUNT*************/
$post = '{
"customer": {
"email": "user@example.com",
"firstname": "John",
"lastname": "Doe"
},
"addresses": [
{
"defaultShipping": true,
"defaultBilling": true,
"firstname": "John",
"lastname": "Doe",
"region": {
"regionCode": "CA",
"region": "California",
"regionId": 12
},
"postcode": "90001",
"street": ["Zoe Ave"],
"city": "Los Angeles",
"telephone": "555-000-00-00",
"countryId": "US"
}
],
"password": "test@1234"
}';
$ch = curl_init("http://your-domain.com/index.php/rest/V1/customers");
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/json", "Authorization: Bearer " . json_decode($token)));
$result = curl_exec($ch);
echo '<pre>'; print_r(json_decode($result)); echo '</pre>';
curl_close($ch);
/*********CREATE A CUSTOMER ACCOUNT ENDS HERE*************/
For the above example to create a customer account, REST Web API call has been constructed in the following way:
- Open <Magento Dir>/vendor/module-customer/etc/webapi.xml file.
- Find the route element that defines createAccount call -
<route url="/V1/customers" method="POST">
<service class="Magento\Customer\Api\AccountManagementInterface" method="createAccount"/>
<resources>
<resource ref="anonymous"/>
</resources>
</route>
Here, endpoint of cURL request is having resource – V1/customers which is as same as route url defined above under url attribute in <route> tag.
- Now, open <Magento Dir>/vendor/module-customer/Api/AccountManagementInterface.php file.
Here, you will see a function:
public function createAccount(
\Magento\Customer\Api\Data\CustomerInterface $customer,
$password = null,
$redirectUrl = ''
);
There are 3 parameters of createAccount function -
$customer – is a data object which is required.
$password – is optional
$redirectUrl – is optional
To pass the customer data object in the POST call payload, specify JSON or XML request body on the call.
Following is the code to retrieve information about a customer:
<?php
/*****VIEW A CUSTOMER RECORD*********/
$ch = curl_init("http://your-domain.com/index.php/rest/V1/customers/1");
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "GET");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/json", "Authorization: Bearer " . json_decode($token)));
$result = curl_exec($ch);
echo '<pre>'; print_r(json_decode($result)); echo '</pre>';
curl_close($ch);
exit();
/*****VIEW A CUSTOMER RECORD ENDS HERE*********/
Here, this code will fetch the record of customer having ID – 1.
Following is the code to retrieve the information about a product:
<?php
/*****VIEW A PRODUCT RECORD*********/
$request = "http://your-domain.com/index.php/rest/V1/products/24-MB01";
$ch = curl_init($request);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "GET");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/json", "Authorization: Bearer " . json_decode($token)));
$result = curl_exec($ch);
echo '<pre>'; print_r($result); echo '</pre>';
curl_close($ch);
/*****VIEW A PRODUCT RECORD ENDS HERE*********/
Here, this code will fetch the record of product having code – 24-MB01.
I hope that this article would be helpful to you. I will continue to explain about SOAP and OAuth in next article.
