# Bank information

To validate BSB, BIC (aka SWIFT code) or IBAN use the bankInfo query.

{% hint style="info" %}
The `bankInfo` query accepts only one of `bsb`, `bic`, or `iban` arguments. Otherwise, it will return an error.
{% endhint %}

The below sample queries will return `null` if the BSB, BIC, IBAN is not found.
