Retrieve an Instrument Identifier with an Unmasked Card Number {#tms-ii-retrieve-unmasked-card-intro}
=====================================================================================================

This section describes how retrieve an instrument identifier with an unmasked card number.

> IMPORTANT
> To retrieve unmasked payment details, you must ensure that your MLE key pair and your token vault are configured correctly. For more information on MLE keys, see [Token Management Message-Level Encryption Keys](/docs/cybs/en-us/tms/developer/all/rest/tms/tms-onboarding/tms-mle-setup.md ""). For more information on token vaults, see [Token Vault Management](/docs/cybs/en-us/tms/developer/all/rest/tms/tms-onboarding/tms-vault-hierarchy.md ""). If necessary, contact your ` Cybersource ` account manager or customer support.  
> The response is BASE 64-encoded JSON web encryption (JWE) token. The decoded JWE has these elements:

```
{ "alg": "RSA-OAEP-256", //The algorithm used to encrypt the CEK 
    "cty": "json", //The content type 
    "typ": "JWT", //The token type 
    "enc": "A256GCM", //The algorithm that is used to encrypt the message 
    "kid": "keyId" //The serial number of shared public cert for encryption of CEK
} 
<Encrypted Data> //The encrypted payload that matches the JSON response normally returned by the TMS API, except with an unmasked payment details
```

Header Configuration {#tms-ii-retrieve-unmasked-card-intro_tms-ii-retrieve-unmasked-card-header}
------------------------------------------------------------------------------------------------

You must pass this request header to retrieve unmasked payment details: `Accept: application/jose`.  
The term `application/jose` refers to Javascript Object Signing and Encryption (JOSE). JOSE is a framework that provides end-to-end security to JavaScript Object Notation (JSON)-based data structures. JOSE achieves this by offering a collection of specifications to encrypt and digitally sign JSON payloads. In this case, the response is message-level encrypted using a JSON Web Token (JWT).
