# Create client

`POST /api/clients`

Create a new client with proper data separation.

This endpoint follows the correct client creation pattern:
1. Client basic info goes to Cliente table (nome, nif, contacto, etc.)
2. Email goes to Emails table (id_modulo=12, id_modulo_id=client_id)
3. Address goes to Moradas table (id_modulo=12, id_modulo_id=client_id)

Automatically assigns the client to the authenticated user's company.
Validates NIF uniqueness within the company.
