  title: Tink Account Check Accounts API
  description: 'Tink Account Check verifies that a bank account belongs to the person or business presenting it. After a customer authenticates via Tink Link the Account Check report exposes verified account ownership, identity, IBAN or sort-code/account number, account type, balance, and holder match status. The report can be retrieved as JSON for programmatic use or as a PDF for compliance archives.
