Check IBAN data when customers enter SEPA direct debit details.
SEPA IBAN validation API
Validate IBANs before SEPA payments fail
Use the IBAN-Test API before SEPA direct debit and payment submissions to catch typos, invalid check digits and available bank data issues earlier.
Reduce avoidable SEPA failures
Failed SEPA payments often start with simple input mistakes. Validate IBANs before mandates, checkout records or payment runs move downstream.
Run checks before exporting or submitting payment data to reduce preventable rejects.
Use API validation in SaaS, accounting, ERP and back-office workflows.
