Input

{
  "verificationDate": "2026-06-30",
  "maxChecks": 100,
  "includeFullBankAccount": false,
  "records": [
    {
      "reference": "invoice-001",
      "identifierType": "nip",
      "identifier": "5260250274",
      "bankAccount": "18101014690032611391200000"
    }
  ]
}

You can also use nip or regon fields directly instead of identifierType + identifier.

Output

Each dataset item contains:

input reference,
identifier type and normalized identifier,
masked bank account,
official accountAssigned result (TAK / NIE),
boolean isAssigned,
MF requestId,
MF request time,
error details for failed checks.

Full bank account echo is disabled by default. Enable includeFullBankAccount only when you need it for your own audit export.
