# BinCountryMismatchContributorConfig

A model the API reference uses in a request or a response. The operation pages link every field typed as this model here.

BIN Country Mismatch configuration: which pairs of countries must agree for a transaction to
pass.

## Fields
- `enabled` (boolean): Whether this rule runs. False, the default, means the rule is skipped and never flags a  transaction. A rule that is enabled but has no usable settings also screens nothing.
- `actionWhenTriggered` ([ActionWhenTriggeredType](https://devportal.demo.winkpg.io/docs/api/models/ActionWhenTriggeredType.md)): What happens when this rule flags a transaction. `AuditOnly`, the default, records the  detection and lets the transaction continue. `Stop` halts the transaction before  authorization, and the caller receives HTTP 403 with the error code  `SCREENING_STOPPED`. `HoldForReview` parks the transaction on the fraud review  queue until a reviewer approves or declines it, or the merchant's hold deadline passes.  Whatever the action, the verdict is recorded on the transaction.
  Values:
  - `AuditOnly`
  - `Stop`
  - `HoldForReview`
- `settings` ([BinCountryMismatchSettings](https://devportal.demo.winkpg.io/docs/api/models/BinCountryMismatchSettings.md)): The comparisons to run. Null leaves the rule unconfigured, which screens nothing.
  Fields:
  - `compareIssuerToBilling` (boolean): Flag a transaction whose card issuer country differs from its billing address country. Null  or false leaves this comparison off. (nullable)
  - `compareIssuerToIp` (boolean): Flag a transaction whose card issuer country differs from the country of the cardholder IP  address. Null or false leaves this comparison off. (nullable)
  - `compareBillingToIp` (boolean): Flag a transaction whose billing address country differs from the country of the cardholder  IP address. Null or false leaves this comparison off. (nullable)
