# Payments Examples

> Runnable payments examples per language: Pix + QR, vouchers, card via Payment Element, 3DS, refunds and pagination.

Working code for the Payments flow: create a Pix charge and return `pix.qr_code`; retrieve and
reconcile a transaction; voucher/boleto with asynchronous instructions; card via
[Payment Element](/frontend/payment-element/overview) → `pgct_*` token → backend, continuing 3DS on
`next_action`; full and partial refunds; and listing transactions with cursor pagination.

## Operations exercised

`postTransactions` · `getTransactions` · `getTransactionsById` · `putTransactionsById` ·
`putTransactionsByIdRefund`

<Note>
  Card data never reaches your backend as a PAN or CVV. It is tokenized in the browser by the Payment
  Element into a `pgct_*` token, which the backend example then charges.
