I am new to REST Api, I am working on to create customer account via using Rest API but struggling with one error which I am trying to find I authorized account properly but when I try to create new account It gives me an error

First Error

{ "message": "%fieldName is a required field.",
"parameters": {
    "fieldName": "customer"
},

Second Error (After adding Customer Param)

In body you've to sent data like the following below.
{
  "customer": {
    "email": "[email protected]",
    "firstname": "your first name",
    "lastname": "your last name",
    "store_id": 1,
    "addresses": [
      {
         "firstname": "your first name",
          "lastname": "your last name",
         "city": "DElhi",
          "street": [
          "117/38"
        ],
        "telephone": "99999999999",
        "country_id": "SA"
      }]
  },
  "password": "admin@123"
}
