Validation codes

Each IBAN validation returns a validations containing the results of each validation that was applied to the given IBAN in this format:

{
    "code": string, // unique validation code
    "valid": boolean, // true if the validation passed
    "message": string // verbose message explaining the validation result
}

Here are the validation codes that are currently supported:

Order	Code	Description
1	`BASIC_FORMAT`	The IBAN has correct format (letters and numbers only)
2	`COUNTRY_CODE`	The IBAN has a valid & supported country code
3	`LENGTH`	The IBAN has a valid length
4	`CHECKSUM`	The IBAN has a valid checksum
5	`BBAN_FORMAT`	The IBAN has a valid BBAN format based on the country rules

If a validation fails, the API will stop processing the remaining validations, and immediately return the validations array.

If the validation fails, the details field of the response will be null.
