Using Custom Data Types

At present, TokenEx maintains up-to-date validations for major card brands. Using the custom data type feature enables you to extend/alter the default validation logic when in PCI mode based on the card types you accept, including private-label and country-specific card brands.

You can supply an array of custom types in your configuration object's customDataTypes property.

Parameter	Type	Required	Description
type	string	true	The name to be returned to you during validation events; using an existing type will override/replace TokenEx default validation
validRegex	string	true	Regular expression used to validate the input. Related: Card Type Validation Regexes
possibleRegEx	string	true	Regular expression used to partially validate the input This is commonly used to toggle logos/images of the brand detected while the user is typing. Related: Card Type Validation Regexes
maxLength	string	true	Max length of the expected input
cvvValidRegex	string	false	Required when in PCI w/CVV or CVV Only mode
cvvMaxLength	string	false	Required when in PCI w/CVV or CVV Only mode
cvvRequired	string	false	Allows a blank CVV input when false
luhnCheck	bool	false	Indicates the system to verify Luhn compliance on custom card schemes Default value is set to True Note: - There will not be (Luhn compliance) format validation error if enforceLuhnCompliance parameter is set to false. This will suppress the JavaScript Luhn check error, allowing the user to send the request to the backend. However if the token scheme doesn't allow skipping the Luhn check, the token generation will still error.
