BinRangeRegexp

Matches transactions whose card BIN matches (or does not match) a configured regular expression. Shown as "BIN Range matches RegExp" in the condition catalogue.

Parameters

Field	Type	Required	Allowed values
regexp	string	yes	PCRE-style regular expression (without delimiters), applied to the card's BIN digits
comparator	string	yes	"eq" (matches) or "neq" (does not match)

Example

Match Visa BINs starting with 4 followed by any 5 digits:

{
  "constraint": "BinRangeRegexp",
  "params": {
    "regexp": "^4[0-9]{5}",
    "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 card's BIN digits — these may be 6 or 8 digits, so avoid $-anchored 6-digit patterns. Backslashes inside the pattern must be JSON-escaped.
• If the transaction has no card or the BIN is empty, rule evaluation stops and the default connector is used.
