Token Formats
Token format overview
Although all formats are supported and compliant according to PCI DSS we highly recommend using the
Alias 2.0 format to run certain operations and obtain the maximum of security.
Please refer to Convert API if you want to migrate from a legacy to the new format. The Alias 2.0 is our default token format. All the tokens are unique. When using the Alias 2.0 format we additionally return the parameter
fingerprint from our APIs. It's a unique identifier for the underlying card. This allows you to identify the same card usage across different customer accounts. Input | Output |
