Magento 2 : Social Login via Rest Api

Question

I need to create a user account using social network via the API.

I have created via native iOS application that hooks into magento 2 store API. However, I can not find a way to create an account using any of social extensions. They add buttons however they do not expose any functionality over rest API for creating accounts or login.

Answer 1

1) First Create webapi.xml declare url, interface and method

<?xml version="1.0"?>
<routes xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Webapi:etc/webapi.xsd">

    <route url="/V1/fetch/sociallogin" method="POST">
        <service class="HIT\Customer\Api\SocialLoginCustomerInterface" method="socialLogin"/>
        <resources>
            <resource ref="anonymous"/>
        </resources>
    </route>

</routes>

2) create di.xml for dependency injection

<?xml version="1.0"?>

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">

    <preference for="HIT\Customer\Api\SocialLoginCustomerInterface" type="HIT\Customer\Model\SocialLoginCustomer" />

</config>

3) create social login interface SocialLoginCustomerInterface.php

<?php
namespace HIT\Customer\Api;

interface SocialLoginCustomerInterface
{
      /**
     * Returns greeting message to user
     *
     * @api
     * @param string $name Users name.
     * @return string Greeting message with users name.
     */
    public function socialLogin();
}

4) create SocialLoginCustomer.php for logic

<?php

namespace HIT\Customer\Model;

use HIT\Customer\Api\SocialLoginCustomerInterface;
use Magento\Framework\App\RequestFactory;
use Magento\Customer\Model\CustomerExtractor;
use Magento\Customer\Api\AccountManagementInterface;

    protected $_encryptor;
    /**

     */
    protected $customerFactory;
    /**
     * @var RequestFactory
     */
    protected $requestFactory;

    /**
     * @var CustomerExtractor
     */
    protected $customerExtractor;

    /**
     * @var AccountManagementInterface
     */
    protected $customerAccountManagement;

    /**
     * @var Config\Source\BrandOptions
     */
    protected $brandOptions;

    /**
     * @var \Magento\Customer\Model\ResourceModel\CustomerRepository
     *
     */
    protected $customerRepository;
    /**
     * @var \Magento\Customer\Model\AddressFactory
     */
    protected $addressFactory;
    /**
     * @var \Magento\Customer\Model\ResourceModel\Customer\Collection
     */
    protected $customerCollection;
    /**
     * @var \Magento\Framework\App\ResourceConnection
     */
    protected $_resource;

    /**
     * CreateCustomer constructor.
     * @param \Magento\Framework\App\Request\Http $request
     * @param EncryptorInterface $encryptor
     * @param \Magento\Customer\Model\CustomerFactory $customerFactory
     * @param RequestFactory $requestFactory
     * @param CustomerExtractor $customerExtractor

     * @param Config\Source\MotherTongue $brandOptions
     */
    public function __construct(
        \Magento\Framework\App\Request\Http $request,

                $customerData = [
                    'firstname' => $customerInfo['firstname'],
                    'lastname' => $customerInfo['lastname'],

                $request = $this->requestFactory->create();

        exit();
    }
}

5) create table social_login fields are id, customer_id, type, social_id, created_at

Answer 2

At first create a custom rest api with below route. you can follow this link: https://alankent.me/2015/07/24/creating-a-new-rest-web-service-in-magento-2/ to create custom res api.

<!-- ws: social login -->
<route url="/V1/customrestapi/login" method="POST">
    <service class="PackageName\CustomRestApi\Api\SocialloginInterface" method="socialLogin"/>
    <resources>
        <resource ref="anonymous"/>
    </resources>
</route>

Then in the socialLogin method pass the social data as array.Here you can put your logic as shown below code.

/**
* Copyright 2015 Magento. All rights reserved.
* See COPYING.txt for license details.
*/

namespace PackageName\CustomRestApi\Model;

use PackageName\CustomRestApi\Api\SocialloginInterface;
/**
 * Defines the implementaiton class of the calculator service contract.
 */
class Sociallogin implements SocialloginInterface
{

protected $_storeManager;
protected $_scopeConfig;
protected $_objectManager;
protected $_customerFactory;


public function __construct(
\Magento\Store\Model\StoreManagerInterface $storeManager,
\Magento\Framework\App\Config\ScopeConfigInterface $scopeConfig,
\Magento\Framework\ObjectManagerInterface $objectManager,
\Magento\Customer\Model\CustomerFactory $customerFactory
)
{
    $this->_storeManager = $storeManager;
    $this->_scopeConfig = $scopeConfig;
    $this->_objectManager =  $objectManager;
    $this->_customerFactory = $customerFactory;
}

/**
 * Check Login.
 *
 * @api
 * @param string[] $data The array of strings to socialLogin.
 * @return $this
 */
public function socialLogin($data) {
    // json array for data should be {"data":{"email":"[email protected]","password":"password","type":"fb/gp","socialId":"","socialToken":"","firstName":"","lastName":"","dob":"","gender":""}}
    // type is used to identify social media facebook or google+
       if($data['type']=='fb'){
           // facbook login logic goes here
        }
       elseif($data['type']=='gp'){
           // google plus login logic goes here
       }
}
