Receiving data from your sales platform
Quaderno supports two types of integrations: native integrations, which connect directly to Quaderno, and integrations via a payment processor like Stripe or PayPal, which route data through an intermediary. Knowing which type applies to your platform tells you what to configure and what data Quaderno will receive.
Native integrations
Native integrations connect your platform directly to Quaderno — no intermediaries, no missing fields. To connect, you grant Quaderno access via OAuth or provide an API key from your platform.

Quaderno natively supports:
- Payment platforms: PayPal, Stripe, GoCardless, and Square
- E-commerce and digital product platforms: Easy Digital Downloads, Fulfillment by Amazon (FBA), Kajabi, SendOwl, Shopify, and WooCommerce
Integrations via a payment processor
Some platforms don't connect to Quaderno directly. Instead, they send transaction data to Stripe or PayPal, and Quaderno reads it from there.

Quaderno only receives what the payment processor passes on. If your platform doesn't send a field — such as a VAT number for B2B sales or the customer's billing address — Quaderno won't have it either. Prices are always treated as tax-inclusive, with the tax calculated as part of the price.
Platforms commonly used via Stripe or PayPal include Clickfunnels, Jotform, Kartra, MemberMouse, Podia, Squarespace, Systeme.io, Teachable, Teachery, and Thinkific.
When connecting via Stripe or PayPal, check that your platform sends all required billing data — including the customer's address, VAT number for B2B sales, and location evidence. If data is missing, contact your platform's support team.
