Antifraud Status

What it is: payment_antifrauderesult is the field that indicates the result of the Antifraud analysis of a transaction in Link de Pagamento and Checkout Cielo.
Where it appears:
- In the content of the transaction completion notification, as the payment_antifrauderesult field with a numeric value.
- In the response of the query for transaction by Checkout_Cielo_Order_Number.
- On the Cielo website, under E-commerce > Orders > Order Details, in the "Antifraud result" field.
What it represents: represents the result of the risk analysis performed by the Antifraude system integrated with Checkout Cielo and Link de Pagamento. The system analyzes payments using neural networks, transaction history, and cardholder behavior, and classifies the transaction with a risk level or indicates why the analysis was not performed.

4	Moderate risk	The transaction was analyzed and classified as moderate fraud risk.

Monitor the payment_antifrauderesult field in the transaction completion notification to determine how to handle each order:

Analyzed — risk result
- 1 — Low risk: transaction analyzed and approved. The order status will be Paid or Authorized according to the merchant's capture configuration.
- 4 — Moderate risk: intermediate risk level. The handling depends on the configured capture rules.
- 2 — High risk: transaction with high fraud risk. Automatically voided; this behavior cannot be disabled.
Inconclusive / analysis error
- 3 — Not completed: the system could not complete the Antifraude analysis for this transaction.
Not analyzed — known reason
- 0 — N/A: no analysis information available.
- 5 — Authenticated: transaction authenticated by the 3DS protocol and therefore not subject to Antifraude analysis.
- 6 — Not contracted: the Antifraude service is not active for the merchant.
- 7 — Exempt: transaction exempt from analysis by system criteria.
- 8 — Not applicable: payment method not eligible, such as boleto, Pix, QR Code, or a debit card authenticated by 3DS.
- 9 — Recurring transactions: only the first transaction of a recurrence is analyzed. Subsequent recurring charges receive this value and are not submitted for analysis.
ℹ️
The automatic capture configuration can be adjusted on the Cielo website under Settings > Antifraud, 3DS and Capture, with the following options: never capture automatically, always capture automatically, or capture only low-risk transactions.

Antifraude is triggered after the payment authorization flow with the issuing bank and card brand.
Payment methods eligible for Antifraude analysis: credit card, Click to Pay, and Google Pay.
Payment methods not eligible: boleto, Pix, QR Code, and debit cards authenticated by 3DS.
It is not possible to disable the Antifraude service or the automatic void of high-risk transactions.
For recurrences, only the first transaction is analyzed. Subsequent charges return value 9 and are not submitted to Antifraude.
High-risk transactions can be recovered through facial authentication, when the order is eligible for that service.
