Credential error when trying to preserve data - django

Question

I am developing an api in Django Rest Framework, which at the moment only registers new users, but I have a problem and that is that now I am adding a bit of security, which is being controlled by means of tokens, but at the time of entering the token of an authenticated user for the creation of users generates an error of The authentication credentials were not provided, but I send the token as follows:
This is plugin rest client visual studio code
My authentication:
### Login user
POST http://localhost:8000/auth-token/
Content-Type: application/json
{
"username": "hamel",
"password": "contraseña"
}
This return a token b6773c67ecb940ae4fb7c9d49466a01fd46f5eb4
My register of user:
### Create User
POST http://localhost:8000/api/v1/users
Authorization: Token b6773c67ecb940ae4fb7c9d49466a01fd46f5eb4
Content-Type: application/json
{
"first_name": "Carlos",
"last_name": "Carlos",
"username": "carlos",
"email": "correo#rgrgr.com",
"password": "contraseña",
"password2": "contraseña"
}
My setting.py:
REST_FRAMEWORK = {
'DEFAULT_PERMISSION_CLASSES': [
'rest_framework.permissions.IsAuthenticated',
],
'DEFAULT_AUTHENTICATION_CLASSES': [
'rest_framework.authentication.TokenAuthentication',
]
}
This my views.py:
class CreateUser(APIView):
authentication_classes = [TokenAuthentication]
permission_classes = [IsAuthenticated]
def post(self, request, format=None):
serializer = UserSerializer(data=request.data)
if serializer.is_valid():
serializer.save()
return Response(serializer.data, status=status.HTTP_201_CREATED)
return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
