# activationData

The request’s activation data.

## Declaration

```swift
var activationData: Data? { get set }
```

## Discussion

Discussion This property contains the data provided to the payment network as a cryptographic one-time pad (OTP), per the Payment Network API specification. The cryptographic OTP is not interpreted by Apple or iOS. The OTP should be verified by the issuer and/or payment network upon receipt of the provisioning request to ensure the request’s authenticity. For more information about the activation data’s content, contact your payment network. note: This is the same type of activation data that is accepted by the pass library’s activate(_:withActivationData:completion:) method.
