Retrieve data based on VAT number from api.stat.gov.pl [PrestaShop 1.6, 1.7, 8.x, 9.x]

Get company data by NIP/VAT (GUS/REGON) module is a practical PrestaShop extension that automatically fills in a customer’s company details based on the NIP/VAT number—without manually typing the business name and address. The integration uses the REGON (GUS) API available at api.stat.gov.pl.

Why is it worth it?

• Faster checkout – the customer enters the NIP and the form automatically completes the company details.
• Fewer invoice data errors – no more typos in the company name, address, or postal code.
• Better B2B UX – automation that truly improves the buying experience.

New features and module capabilities

• Front-Office & Back-Office support – separate toggles in the configuration:
  • auto-fill data in the customer address form (FO),
  • auto-fill data when adding/editing addresses in the admin panel (BO).
• Loader on the VAT/NIP field – the pm-input-loading class adds a visual indicator while data is being fetched.
• Auto-fill additional fields – besides name and address, the module can also insert e.g. phone and website (if available).
• AJAX request protection – a token mechanism limits calls to the correct shop context.
• Compatible with PrestaShop 1.6+, 1.7, 8.x, 9.x

How does it work in practice?

1. The customer (or administrator) enters the NIP in the VAT/NIP field in the address form.
2. The module sends a request to the REGON (GUS) API and retrieves the entity data.
3. The form fields are filled automatically—without reloading the page.

Which data can be auto-filled?

• Company name
• Street and building number
• Postal code and city
• Phone number (if available)
• Website (if available)

Requirements

• REGON API user key (token) – obtainable via the GUS API portal.
• Enabled SOAP extension in PHP (communication with the REGON service)
