Create customer By Graphql Mutation

We can create custom mutation for create customer by graphql. For that we can create custom request and response query string.

Step 1. Create a schema.graphqls file in your module's etc directory.

Copy

                            
                                type Mutation {	
	createCustomerAccount(		
	    id: String @doc(description: "Id of requested resource")
		firstname: String! @doc(description: "The customer's name")
		lastname: String @doc(description: "The customer's family name")
		phone: String! @doc(description: "The customer's Phone number")
		email: String! @doc(description: "The customer's email address. Required")
		password: String @doc(description: "The customer's password")
		gender: String @doc(description: "The customer's gender")
		registrationchannel: Channel @doc(description: "The customer's registration channel")		
	): CreateCustomerResponse @resolver(class: "\\Vendor\\CustomerLogin\\Model\\Resolver\\CreateCustomer") @doc(description:"Create customer account")
}

enum Channel {
  WEB
  SOCIAL
  APP
}

type CreateCustomerResponse {
    status: Boolean @doc(description: "Request Status")
    message: String @doc(description: "Success Message")
}

Step 2. No need to create resolver class, which have you log in to creating customer

Copy

                            
                                <?php

namespace Vendor\CustomerLogin\Model\Resolver;
 
use Magento\Framework\GraphQl\Config\Element\Field;
use Magento\Framework\GraphQl\Exception\GraphQlInputException;
use Magento\Framework\GraphQl\Exception\GraphQlAuthenticationException;
use Magento\Framework\GraphQl\Query\ResolverInterface;
use Magento\Framework\GraphQl\Schema\Type\ResolveInfo;
use Magento\Framework\Math\Random;
use Psr\Log\LoggerInterface;
 
/**
 * Create Customer field resolver, used for GraphQL request processing
 */
class CreateCustomer implements ResolverInterface
{

    /**
     * @var Random
     */
    private $mathRandom;
            
    /**
     * @param Random $mathRandom
     * @param LoggerInterface $logger
     */
    public function __construct(
        Random $mathRandom,
        LoggerInterface $logger
    ) {
        $this->mathRandom = $mathRandom;
        $this->logger = $logger;
    }

    /**
     * @inheritdoc
     */
    public function resolve(
        Field $field,
        $context,
        ResolveInfo $info,
        array $value = null,
        array $args = null
    ) {
        $this->vaildateArgs($args);
        $id = '';
        if (isset($args['id'])) {
            $id = $args['id'];
        }
		
        try {
            return ['status' => 1, 'message' => "", 'data' => ""];
        } catch (\Exception $e) {
            throw new GraphQlAuthenticationException(__($e->getMessage()), $e);
        }
    }

    /**
     * Vaildate the arguments
     *
     * @param array $args
     * @throws GraphQlInputException
     */
    private function vaildateArgs(array $args): void
    {

        if (empty($args['firstname'])) {
            throw new GraphQlInputException(__('Specify the "name" value.'));
        }
    }
}

Step 3. This mutation query your can run in by postman

Copy

                            
                                mutation{
createCustomerAccount(
            firstname: "Ajeet"
            lastname: "Singh"
            email:"ajeet1s@razorpay.com"
            phone:"8303523417"
            gender: "1"
            registrationchannel:WEB
        ) {
    message
    status
  }
}
