# merchantIdentifier

A value that represents the merchant that makes the request.

## Declaration

```swift
var merchantIdentifier: String? { get set }
```

## Discussion

Discussion This property identifies the merchant making the request, and must match one of the merchant identifiers in the app’s entitlement. For information about configuring the entitlement, see com.apple.developer.in-app-identity-presentment.merchant-identifiers. Set this property before you invoke requestDocument(_:completion:).
