5 Steps to Make a Magento Rest API Call

Step 1: Open the file Magento/Customer/etc/webapi.xml.

Step 2: Find the route element defining the createAccount call:

<route url="/V1/customers" method="POST">
   <service class="Magento\Customer\Api\AccountManagementInterface" method="createAccount"/>
   <resources>
      <resource ref="anonymous"/>
   </resources>
</route>

Step 3: Construct the URI using the method and URL values from the route element. Here, POST /V1/customers is the URI.

Step 4: Identify the service interface using the class attribute in the service element.

The interface is AccountManagementInterface.

Locate the createAccount method in AccountManagementInterface.php:

public function createAccount(
     \Magento\Customer\Api\Data\CustomerInterface $customer,
     $password = null,
     $redirectUrl = ''
 )

A customer data object is required. Password and redirectUrl are optional with default values.

Step 5:Mention the JSON or XML request body to pass the customer data object in the POST call payload.

4 Elements of Magento 2 Rest API

1. HTTP Headers

HTTP headers are crucial for API communication. They define metadata and parameters for the requests. Here are the three main headers:

HTTP Header	Description	Syntax
Authorization	Required header for authentication. Uses a token to verify account ownership.	Authorization: Bearer <TOKEN>
Accept	Optional header to specify the response format. Defaults to JSON if not specified.	Accept: application/<FORMAT>
Content-Type	Required for requests with a body. Specifies the format of the request body.	Content-Type: application/<FORMAT>

2. HTTP Verb

HTTP verbs determine the action performed by the request. They specify what the server should do with the resource. Here are the main verbs:

HTTP Verb	Action
GET	Requests the current representation of the target resource. Default if no verb is specified.
PUT	Creates or replaces the target resource with the state defined by the request payload.
POST	Submits the request payload as new data to be processed by the target resource.
DELETE	Requests the deletion of the target resource.

3. Endpoint

Endpoints combine server, web service, store code, and resource. Follow these steps to understand endpoints:

• Identify the server: This is the base URL (e.g., http://magento.ll/index.php).

• Determine the web service: Usually, it's /rest.

• Select the resource: Specifies what part of Magento you are interacting with (e.g., /V1/customerGroups).

• Include template parameters: Use parameters like id to target specific data.

4. Call Payload

The call payload includes input parameters and attributes. Follow these steps to use call payloads effectively:

• Specify input parameters: Define these in the URI (e.g., GET/V1/customers/:customerId requires customerId).

• Define input attributes: Include these in the request body formatted as JSON or XML.

• Structure the request body: For instance, in a POST /V1/customers call, provide customer details:

  {
      "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",
