clients

This API endpoint allows you to create a new client within an organization.
It stores the client’s identification, contact, address, and contract-related information, including name, registration details, VAT code, contact details, preferred language, status, and optional notes. The client is associated with the authenticated user who creates it, and creation is subject to organizational permissions and validation rules.
