# Suggest Banks for an Account Number

> When you have an account number but not the bank: returns banks we have previously paid this account number through. A hint, not a lookup; still call verify with the code you pick.

## Overview

When you have an account number but not the bank, this returns the banks we have previously paid that account number through. It is a hint from past transfers, not a lookup against the banking network: the list can be empty, and you should still [verify](/api-reference/banks/verify) with the code you pick.

  description: >-
    Platnova's Business API allows businesses to issue virtual accounts and
    cards to their employees, vendors, or retail customers. It allows businesses
    to streamline the process of issuing cards, manage spending, and track
    transactions. The API documentation provides information on how to integrate
    our virtual card issuing system into a business's existing systems and
    outlines the features and functionalities of the API, including card and
    account creation, management, and reporting. It also provides technical
    specifications, such as API requests, responses, and authentication
    processes.


    The API documentation is intended for developers and IT teams to use in
    order to effectively implement Platnova solutions into their business
    processes.


    # Authentication/Authorization


    To access any of the resources on the `{BaseUrl}/v1/`, the client has to
    pass pre-defined headers for authentication and authorization.


    The API is secure and only authorized clients can consume the service. There
    are API keys assigned to every business and JWT tokens assigned to every
    account for authentication/authorization.


    ## Bearer Token


    Requests may accept jwt tokens as below.


    ``` json

    Authorization: Bearer <jwt token>

     ```

    ## API Key


    Requests may acccept an api key either in the request headers or as a query
    parameter. Some requests cannot be authorized using an API key.


    ``` json

    X-API-KEY: <api key>

     ```

    OR


    ``` json

    ?api-key=<api key>

     ```
