Bank Suite API Documentation

This API is part of our Bank Suite service

1. Introduction

The Bank Suite is a web service which provides validation capabilities for bank codes and account numbers.
Designed mainly to provide bank code and account number validation for countries which do not use the IBAN standard (see list of countries ).
Powered by the one of the largest and up to date bank code directories in the industry it is a powerful suit of services helping businesses improve the quality of international payments

2. Features

Some of the key features and benefits of the Bank Suite service are:

Global Coverage
Validate Bank Codes for non-IBAN and IBAN countries
Validate domestic bank code and account number check digits
Monthly updated world bank directory covering 195 countries
Query the bank suite directory by Bank Code(National ID)
Query the bank suite directory by BIC code
Validate Bank Code structure
Validate Bank Code length
Identify BIC code related to bank routing/sorting code

3. API Endpoints

The Bank Suite API provides the following endpoints:

Main Endpoint - Validate bank code (NID)
http://api.iban.com/clients/api/banksuite/nid/

This endpoint is used to validate bank codes and retrieve information about the bank and branch they belong.
It also provides an additional feature to validate bank account numbers by checking their structure, formatting, length and check digit.

BIC Endpoint - Search by BIC Code
http://api.iban.com/clients/api/banksuite/bic/

This endpoint performs validation on a provided BIC code and performs a search in our banking directory.
If the BIC is currently active and in use, the system will provide bank code and bank and branch information related to this BIC

Structure Endpoint - Information about format and structure.
http://api.iban.com/clients/api/banksuite/structure/

The structure endpoint provides information about bank code and account number structure for each specific country.

4. Bank Code API Input

The REST API accepts both HTTP GET or POST requests.
The input parameters are listed in the table below:

Field Name	Length	Type	Description
nid	Max 15	String	The Bank Code sent to our system for validation.
account	Max 50	String	(optional) Account number sent for validation.
country_iso	Max 2	String	2 letter ISO Code of the country. List of supported countries in Section 8. Supported Countries
api_key	128	String	Your personal API key.
format	5	String	Format of the response XML and JSON supported.

*To obtain an API key, please contact us at contact@iban.com or purchase a subscription at our order page

An example usage of the BankSuite API with a GET request can be:

https://api.iban.com/clients/api/banksuite/nid/?format=json&api_key=[API_KEY]&country_iso=US&nid=322271627

Where:

key is your API key
NID is the bank code sent for validation by the API module.
xml is the response format. Also a json keyword can be specified for json formatted response.

Once an HTTP GET or POST request is made with the correct API key, the system will return the results in the specified format.

ACCOUNT_VALID	Boolean	True or False. Indicates if the account number supplied has passed all validations
NID_VALID	Boolean	True or False. Indicates if the bank code has passed all validations
RECORDS_FOUND	Integer	Indicates the number of records found in the bank directory. If more than one, you may use the 'limit' parameter to retrieve multiple records for the same bank code
RECORDS_DISPLAYED	Integer	Indicates the number of records displayed in the 'directory_results' object. By default we display one record. With the 'limit' parameter, you can retrieve multiple
DIRECTORY_RESULTS	Array	This object contains the data retrieved from our bank directory for the respective bank code. You may find a detailed description of this object in Section 7 Data Field Definitions

Field Name	Length	Type	Description
country_iso	2	String	The 2 letter ISO country code submitted by the client
api_key	128	String	Your personal API key.
format	5	String	Format of the response XML and JSON supported.

An example usage of the BankSuite API with a GET request can be:

https://api.iban.com/clients/api/banksuite/structure/?format=json&api_key=[API_KEY]&country_iso=GB

Where:

key is your API key
country_iso is the 2 letter ISO country code you need the formatting data for.
xml is the response format. Also a json keyword can be specified for json formatted response.

Once an HTTP GET or POST request is made with the correct API key, the system will return the results in the specified format.

6.1 Structure API Output

An XSD Schema of the API’s response can be found below:
XSD Schema for Structure endpoint: download

The API results are delivered in JSON or XML format for maximum usability. Find below descriptions for the JSON properties returned by the API:

Object	Type	Description
success	Boolean	Indicates a true or false indicating if the query succeeded
national_id_format	Object	This object contains data for the format and structure of the Bank Code
account_number_format	Object	This object contains information about the structure, length and formatting of the domestic bank account number for the specified country.
error	Object	Provides error code and description if an error occurs. For descriptions, please refer to Section 6.2 Structure API Errors

A sample JSON reply from the API for a IBAN validation query would be:
