Validating bank accounts

Bank account numbers can be validated for free through our API. This is especially useful for use in data entry forms. Validation of bank accounts applies Check Digit Validation (CDV) logic to quickly identify any obvious problems with an account number and account type and branch code combination. Account numbers can only be validated in one way:

POST: ​/verify​/cdv

This will validate the bank account number, account type and branch code provided:

• Rate limit: 1 per second

• Payload size: 1

The full response model includes:

[
  {
    "isValid": true,
    "success": true,
    "message": "string"
  }
]
