CreditcardCardNetwork

Matches follow-up transactions whose card network is in a configured list. Shown as "Credit card: Card Network" in the condition catalogue. Card networks are coarser-grained than card brands — useful for routing rules that apply to an entire network's traffic.

This condition applies to follow-up transactions that reference an initial transaction: the card network is determined from the initial transaction. Transactions without a reference transaction never match.

Parameters

Field	Type	Required	Allowed values
cardNetworks	array of strings	yes	One or more network identifiers from the list below (lowercase)
comparator	string	yes	"in"

Network identifiers

visa, mastercard, nyce, star, accel, amex, cartes_bancaires, jcb, diners, discover, mada, maestro, omannet, pulse, upi

Example

{
  "constraint": "CreditcardCardNetwork",
  "params": {
    "cardNetworks": ["visa"],
    "comparator": "in"
  }
}

Notes

• Availability: might not be included in your platform package — if this condition is missing from the catalogue returned by List routing constraints, contact your Customer Success Manager to have it activated.
• Network identifiers are case-sensitive and must be lowercase.
• Only the in comparator is supported. To express "not in network X", nest two rules and swap the then / else branches.
