title: "Removed no_vat parameter from registration APIs"

The `no_vat` parameter has been removed from all company registration endpoints across REST and SOAP APIs. This parameter previously allowed skipping VAT validation when registering companies, but is no longer needed or supported.

## Affected API endpoints

**SOAP API:**

- `register` - `no_vat` field in `RegistrationParamsIn` struct
- `register_with_password` - `no_vat` field in `RegistrationParamsIn` struct  
- `register_with_odp_company_id` - `no_vat` field in `RegistrationParamsIn` struct  

**REST API:**

- [POST /api/v1/companies](https://swagger.maventa.com/?urls.primaryName=PROD+-+AutoXChange+API#/companies/postV1Companies) - `no_vat` parameter
- [POST /api/v1/company_departments](https://swagger.maventa.com/?urls.primaryName=PROD+-+AutoXChange+API#/company/postV1CompanyDepartments) - `no_vat` parameter

## What this means

The system now automatically handles business identifier validation without requiring manual specification of whether the identifier is a VAT number or not. Any `no_vat` parameter sent to registration endpoints will be ignored.

If you're currently using the `no_vat` parameter in your integration, you can simply remove it from your API calls. The registration process will continue to work correctly without it.
