What is wFirma API? wFirma 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 wFirma account. * Generate invoices and proforma invoices (PRO version). * Generate receipts (paragony fiskalne) and sales receipts (dowody sprzedaży / paragony niefiskalne) for retail customers (PRO version). * Retrieve bank accounts, VAT codes, and other accounting data from your wFirma account. * Download invoice PDFs. * Synchronize warehouse stock between WooCommerce and wFirma (PRO version). What data is sent and when? The plugin sends the following data to wFirma API (https://api2.wfirma.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 wFirma API (on settings page load or when needed): * Your wFirma Access Key and Secret Key (for authentication). * Requests to retrieve your account settings: bank accounts, VAT codes, income categories, warehouse data (PRO version). No data is sent automatically without your action. The plugin only communicates with wFirma 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).
