Ladies and Gentlemen, we would like to inform you that due to the lack of publication today flat file by the Ministry of Finance, function getWhitelistStatus is unable to return the correct data for today. As soon as the flat file is published, the function should automatically start returning information for today.
Alternatively, you can use the function getIBANStatus , which performs exactly the same function of checking the status of an entity's bank account in the list of VAT payers (the so-called VAT white list), but using the API interface.
We apologize for inconveniences
