External services

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

What is Pennylane API?

Pennylane is a French online accounting platform that provides invoicing and accounting services for businesses. This plugin uses their official API to:
* Create and manage customers in your Pennylane account.
* Generate customer invoices (factures).
* Retrieve invoice data and PDF documents.
* Mark invoices as paid (PRO version).
* Sync product catalog data (PRO version).

What data is sent and when?

The plugin sends the following data to Pennylane API (https://app.pennylane.com/api/external/v2/) 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, SIRET number, VAT number, 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 Pennylane API (on settings page or when needed):
* Your Pennylane API Key (for authentication via Bearer token).
* Requests to retrieve your account information, customer data, and invoice status.

No data is sent automatically without your action. The plugin only communicates with Pennylane API when:
* You manually create an invoice from the order screen.
* You click “Test Connection” on the settings page.
* You download an invoice PDF.
* You enable automatic invoice generation in PRO version.
