The Financial Validator API can validate EU VAT numbers, International Bank Account Numbers (IBAN), and credit/debit card numbers.
The VAT Validation endpoint returns the company name, address, and validity status of the EU VAT number verified against the official VIES database.
The Card Validation feature uses the Luhn algorithm to check the validity of credit/debit card numbers. It detects the card issuer (such as Visa, Mastercard, or Amex), card type, and Bank Identification Number (BIN).
Yes, the API offers a Batch Validation feature that allows users to process multiple VAT numbers, IBANs, or card numbers in a single request for bulk operations.
The API is designed for fintech applications, e-commerce checkout validation, KYC compliance, and accounting automation, helping businesses ensure the accuracy and validity of financial identifiers.
The Card Validation endpoint response includes fields such as "isValid" (boolean), "issuer" (card brand), "type" (credit or debit), "length" (number of digits), and "bin" (Bank Identification Number), providing essential details about the card.
The response data for the VAT Validation endpoint is structured in JSON format, containing fields like "vatNumber," "isValid," "country," and "checkDigitValid," allowing for easy parsing and integration into applications.
The Batch Validation feature allows users to submit multiple VAT numbers, IBANs, or card numbers in one request, returning a consolidated response with validity statuses and relevant details for each identifier, streamlining bulk processing.
Users can customize their requests by specifying the financial identifier type (VAT, IBAN, or card number) and providing the relevant identifier in the request body. Each endpoint accepts specific formats for the identifiers to ensure accurate validation.
The VAT Validation endpoint sources its data from the official VIES (VAT Information Exchange System) database, ensuring high accuracy and reliability in verifying EU VAT numbers against official records.
The Financial Validator API employs rigorous validation algorithms, such as the Luhn check for card numbers and official database checks for VAT and IBAN validations, ensuring that the data returned is accurate and reliable.
Typical use cases for the IBAN Validation endpoint include verifying bank account details during e-commerce transactions, ensuring compliance in financial services, and automating accounting processes to prevent errors in payment processing.
