# Verification Result

The `VerificationResult` type is the response returned by `SelfBackendVerifier.verify()` from `@selfxyz/core`. It contains the verification status, disclosed identity attributes, and user context data.

## VerificationResult

```typescript
type VerificationResult = {
  attestationId: AttestationId;
  isValidDetails: {
    isValid: boolean;
    isMinimumAgeValid: boolean;
    isOfacValid: boolean;
  };
  forbiddenCountriesList: string[];
  discloseOutput: GenericDiscloseOutput;
  userData: {
    userIdentifier: string;
    userDefinedData: string;
  };
};
```

| `userData.userDefinedData`         | `string`                | Application-defined data passed through the verification flow     |

## GenericDiscloseOutput

The disclosed identity attributes requested during verification. Only fields that were requested in the disclosure configuration will contain meaningful values.

```typescript
type GenericDiscloseOutput = {
  nullifier: string;
  forbiddenCountriesListPacked: string[];
  issuingState: string;
  name: string;
  idNumber: string;
  nationality: string;
  dateOfBirth: string;
  gender: string;
  expiryDate: string;
  minimumAge: string;
  ofac: boolean[];
};
```

## VerificationConfig

The configuration passed to `SelfBackendVerifier` to specify what checks to perform.

```typescript
type VerificationConfig = {
  minimumAge?: number;
  excludedCountries?: Country3LetterCode[];
  ofac?: boolean;
};
```
