External services

This plugin relies on the Fakturownia API, a third-party accounting service, to generate invoices and manage customer data.

What is Fakturownia API?

Fakturownia is a Polish online accounting system that provides invoicing and accounting services for businesses. This plugin uses their official API to:
* Create and manage customers (contractors) in your Fakturownia account.
* Generate VAT invoices.
* Retrieve invoice templates, VAT codes, and other accounting data from your Fakturownia account.
* Download invoice PDFs.

What data is sent and when?

The plugin sends the following data to Fakturownia API (https://*.fakturownia.pl/) in these situations:

When you click “Create Invoice” or when automatic invoice generation is triggered (PRO version):
* Customer billing information: first name, last name, company name, VAT number (NIP), email, phone number, billing address (street, city, postal code, country).
* Order information: order items (product names, quantities, prices, VAT rates), shipping details, payment method, order date, order total.

When the plugin connects to Fakturownia API (on settings page load or when needed):
* Your Fakturownia API Token (for authentication).
* Requests to retrieve your account settings: invoice templates, VAT codes, warehouse data (PRO version).

No data is sent automatically without your action. The plugin only communicates with Fakturownia API when:
* You manually create an invoice from the order screen.
* You enable automatic invoice generation in PRO version.
* You open the plugin settings page (to load account configuration).
* Warehouse synchronization is enabled in PRO version (webhook).
