PCI Tokens

Management of card payment credentials under the ruling of PCI/DSS.

Operations

Network Tokens

Management of network tokens, including cryptograms for secure transactions.

Operations

Create token

Request

Create and provision a new network token with a card scheme.

There are three ways to create the token, which depend on the level of your PCI/DSS compliance:

Source ComplianceDescription
sessionMin. SAQ-A+This is the most common way to create a token. It will leverage the SDKs of Guardian to securely capture the cardholder data and send it encrypted to the API.
panMin. SAQ-D+In case you have the required compliance to handle cardholder data yourself, you can also just import the full data in exchange for a token.
pci_tokenMin. SAQ-A+Use an existing PCI token as source. The network token will be provisioned independently from the PCI token, such that the life-cycles of the tokens are not coupled.
Important information

Currently only Visa, Mastercard, American Express, and Discover are supported as card schemes. The network token will be provisioned with the card scheme.
