Use this section when you are choosing how to accept cards with Pagou. Use Payment Element for new card checkouts. Why:
  • Card entry stays inside a hosted iframe.
  • Tokenization stays outside your DOM.
  • next_action and 3D Secure continue in the same browser session.
  • Your backend keeps control of transaction creation and order state.

​
Card payment model

  1. The browser mounts Payment Element.
  2. Payment Element tokenizes the card.
  3. Your backend calls POST /v2/transactions with method: "credit_card".
  4. Your system waits for final webhook or reconciliation state before fulfillment.
