Transient Token Format {#uc-tokens-format}
==========================================

The transient token is issued as a JSON Web Token (JWT) ([RFC 7519](https://tools.ietf.org/html/rfc7519 "")). For information on JSON Web Tokens, see [JSON Web Tokens](/docs/vas/en-us/digital-accept-flex/developer/all/rest/digital-accept-flex/uc-intro/uc-appendix/uc-appendix-jwts.md "").  
The payload portion of the token is a Base64URL-encoded JSON string and contains various claims. For more information, see [JSON Web Tokens](/docs/vas/en-us/digital-accept-flex/developer/all/rest/digital-accept-flex/uc-intro/uc-appendix/uc-appendix-jwts.md "").

IMPORTANT The empty field values in the transient token indicate which fields were captured by the application without exposing you to personally identifiable information directly.  
PAN BIN in `metadata` Object  
The `cardDetails` object, including the PAN BIN, is included in the transient token `metadata` when a `Click to Pay` network token is used as a payment method. This allows you to display information about the card on invoices and see the BIN details that are linked to the underlying card.

```
"metadata": {
  "cardDetails": {
    "suffix": "9876",
    "prefix": "123456",
    "expirationMonth": "MM",
    "expirationYear": "YYYY"
  }
}
```

Authentication Status in metadata Object  
The `cardholderAuthenticationStatus` object is included in the `metadata` and enables you to determine if the payload is fully authenticated. When `cardholderAuthenticationStatus` is set to `true`, the payload is fully authenticated. When `cardholderAuthenticationStatus` is set to `false`, the transaction is not authenticated.
If you are using `Unified Checkout` with unifiedPayment.complete() and consumerAuthentication is set to `true` in the complete mandate request, then `Payer Authentication` is called automatically if it is available for the selected payment method and card network. If you use a transient token to request follow-on services directly, the value of this field indicates if the transaction has been authenticated.

```
"metadata": {
  "cardholderAuthenticationStatus": "true"
  }
}
```
