antifraud-clearsale

ℹ️

Alphanumeric CNPJs will be implemented by the Brazilian Federal Revenue Service in July 2026

This change applies only to new registrations. There will be no changes to existing CNPJs.

The alphanumeric CNPJ is already supported by Cielo, with no changes required to your integration.

We recommend checking whether adjustments are needed in your merchant’s own checkout systems.

⚠️

Warning

---

If there is integration with the Cielo Gateway de Pagamento API or the API E-commerce Cielo:

• The BraspagTransactionId field is required;
• The BraspagTransactionId field corresponds to the PaymentId returned by the Gateway de Pagamento or API E-commerce Cielo;
• The Tid, Nsu, AuthorizationCode, and SaleDate fields do not need to be sent;
• If the e-commerce operates with antifraud before authorization, the authorization association must be implemented.
• Important: The absence of the BraspagTransactionId parameter or of the analysis-authorization association will prevent automatic chargeback feedback to the antifraud provider.

---

If there is no integration with the Cielo Gateway de Pagamento API and API E-commerce Cielo:

• The Tid, Nsu, AuthorizationCode, and SaleDate fields become required;
• The BraspagTransactionId field does not need to be sent.
