# Radar fraud scores for Issuing authorizations

Get a Radar fraud risk score for your Issuing card authorization transactions.

[Stripe Radar’s](https://docs.stripe.com/radar.md) AI model provides real-time fraud risk scoring for Issuing card authorization transactions. The API returns a fraud risk score and risk level, allowing card issuers and issuer-processors to make informed authorization decisions. You can request a fraud risk evaluation for each card authorization before deciding to approve or decline the transaction.

## Prerequisites

Before you request a fraud risk evaluation on a card authorization, you must have:

- Authorization transaction details, including the `amount`, `currency`, `reference`, and `initiated_at` timestamp.
- Card details, including the card `bin`, `bin_country`, `last4`, `card_type`, card `created_at` timestamp, and `reference`.
- Merchant details, including the `category_code` (MCC), merchant `name`, and `network_id`.

The following diagram shows your call to create an `IssuingAuthorizationEvaluation` and Stripe’s real-time response with the fraud risk score.
