Magento 2 : Customer creation failed using customer API

Question

I am trying to create customer using API in magento 2.2.3.

Below api is working well and customer can created successfully but issue only arrive while adding address.

If i send address field with customer magento show me error like below.

Here is the data i am sending to api

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
 (
 [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);

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
)
