Response when text filter not implemented

Question

In a call to the Get Transactions for Account API, how should the Data Holder (DH) respond if the optional text parameter filter field is provided, but the text filter is not implemented?

Answer

The DH responds with the isQueryParamUnsupported in the meta object as part of the ResponseBankingTransactionList response. The DH returns the full unfiltered result set in the data object.

For example, a generic response would be:

{
  "data": {
    "transactions": [
      {
        "accountId": "string",
        "transactionId": "string",
        "isDetailAvailable": true,
        "type": "DIRECT_DEBIT",
        "status": "PENDING",
        "description": "string",
        "postingDateTime": "string",
        "valueDateTime": "string",
        "executionDateTime": "string",
        "amount": "string",
        "currency": "string",
        "reference": "string",
        "merchantName": "string",
        "merchantCategoryCode": "string",
        "billerCode": "string",
        "billerName": "string",
        "crn": "string",
        "apcaNumber": "string"
      }
    ]
  },
  "links": {
    "self": "string",
    "first": "string",
    "prev": "string",
    "next": "string",
    "last": "string"
  },
  "meta": {
    "totalRecords": 0,
    "totalPages": 0,
    "isQueryParamUnsupported": true
  }
}
