                (
                    [region] => 67
                    [country_id] => CA
                    [countryId] => CA
                    [street] => 3652 Rohnstand Road  
                    [firstname] => name
                    [lastname] => lastname
                    [company] => 3654256542156954
                    [telephone] => 999-999-9999
                    [city] => city
                    [postcode] => pincode
                )

        )

    [password] => password
)

This is how api calling.

    $data = $this->mapData($data);
    $ch = curl_init("http://127.0.0.1/project/index.php/rest/V1/customers");
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
    curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/json", "Authorization: Bearer " . json_decode($this->_token)));

    $result = curl_exec($ch);

Register Customer using API

webapi.xml

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

url http://<magento-host>/rest/V1/customers

url action :: POST

Body > raw > JSON(application/json)

{
"customer":{
    "email":"[email protected]",
    "firstname":"Aditya",
    "lastname":"Shah",
    "websiteId":"1",
    "addresses":[
        {
            "customer_id":"1",
            "firstname":"Aditya",
            "lastname":"Shah",
            "company":"ABC Manufacturing",
            "telephone":"555-555-5555",
            "city":"Boston",
            "region":"Massachusetts",
            "postcode":"02115",
            "country_id":"US",
            "street":[
                "404 Main Street",
                "PO Box 321"
            ]
        }
    ]
},
 "password": "Account@123"
}

Answer 2

Data format was wrong while passing data to api.

we need to pass addresses as multidimensional array.

Here is a data format.

Array
(
    [customer] => Array
        (
            [website_id] => 1
            [store_id] => 1
            [group_id] => 1
            [firstname] => name
            [lastname] => lastname
            [custom_attributes] => Array
                (
                    [customer_code] => 3654256542156954
                )

            [email] => [email protected]
            [addresses] => Array(
                [0] => Array
                        (
                            [region] => 67
                            [country_id] => CA
                            [countryId] => CA
                            [street] => 3652 Rohnstand Road  
                            [firstname] => name
                            [lastname] => lastname
                            [company] => 3654256542156954
                            [telephone] => 999-999-9999
                            [city] => city
                            [postcode] => pincode
                        )
                )

        )

    [password] => password
)
