Good day.

I am trying to create new leads via an API call.

I have the following settings configured inside postman:

URL: https://localhost/MyStoreInstance/entity/Default/20.200.001/Lead
HTTP method: PUT

Parameters:
$expand: Contact,Address
$select: Contact/FirstName,Contact/LastName,Address/Country

Headers:
Accept: application/json
Content-Type: application/json

Body:
{

"Contact":[{

"FirstName":{"value":"NewTest"},

"LastName":{"value":"NewTest"}

}],

"Address":{

"CountryID":{"value":"ZA"}

}

}


This is just a basic PUT method to make sure that it is working. I will later add it with correct and more values.

Any help would be greatly appreciated

I am receiving the following internal server error:
