Introduction

IBAN Verification API Services ensure the accuracy and validity of IBANs by performing syntax checks, checksum verification, and other validations to confirm that the provided IBANs are correctly formatted and correspond to the correct country and financial institution. This helps prevent errors and fraud in cross-border payments and ensures the integrity of international banking transactions.

The IBAN Verification API service lets you fetch account information for multiple bank accounts in a Consent ID or a single account using the Account ID.

Consent

User consent is the primary requirement to access any services in Open Banking. The user or account holder grants explicit consent to a Third-Party to access their financial data. This consent is given through a secure, multi-factor authentication process to verify the user's identity.

The consent request must include the following details:

Endpoint	`useCaseType` Value	`permissions` Value
`/v1/api/observice/connect`	`IBANVALIDATIONS`	`ReadAccountsBasic` `ReadAccountsDetail`

Check Consent Management for more details to create, view, and revoke consents.
