IbanRegexp

Matches transactions whose customer IBAN matches a configured regular expression. Shown as "IBAN matches RegExp" in the condition catalogue.

Parameters

Field	Type	Required	Allowed values
regexp	string	yes	PCRE-style regular expression (without delimiters), applied to the customer IBAN
comparator	string	yes	"eq" (matches)

Example

Match IBANs from Germany:

{
  "constraint": "IbanRegexp",
  "params": {
    "regexp": "^DE",
    "comparator": "eq"
  }
}

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.
• The expression is applied to the customer IBAN as a PCRE regular expression. Backslashes inside the pattern must be JSON-escaped.
• If the IBAN does not match the expression, the transaction has no customer, or the customer has no IBAN, the rule is skipped and routing falls through to the default connector.
• Available for routing meta-connectors only — not in multi-method routing documents.
