Payment limits. Choose Always require approval, or give Delegated authority with per-transaction and daily limits up to BRL 1,000.

Pix and NuPay checkout

Let it checkout. You set the payment scope.

When your agent needs to checkout from a merchant, Nu prepares a Pix/NuPay checkout approval. You can require app confirmation every time or let the agent pay within saved payment limits.

  • Always require approval. The agent never moves money on its own. It prepares the checkout and waits for your in-app decision.
  • Delegated authority. Let an agent spend inside your transaction and daily limits, never above BRL 1,000.
  • Funding stays yours. When approval is required, choose Account balance or Pix Financing before confirming.
