IbanRoutingRule

Matches transactions whose customer IBAN contains a configured substring at a configured position — useful for routing rules that depend on a specific bank identifier or country block within the IBAN. Shown as "Check IBAN exact position value" in the condition catalogue.

Parameters

Field	Type	Required	Allowed values
position	integer	yes	1-indexed start position within the IBAN string (e.g. 1 for the first two country-code letters)
value	string	yes	The expected substring to compare against
comparator	string	yes	"eq" (matches)

Example

Match IBANs whose first two characters are DE (Germany):

{
  "constraint": "IbanRoutingRule",
  "params": {
    "position": 1,
    "value": "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 match extracts a substring of the same length as value, starting at position (1-indexed). Lengths and positions must be consistent with the IBAN structure you're checking.
• If 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.
