# August 2, 2022 

** We have made updates to Karbon's public API that impact the Organization endpoint.  **
---

This document provides an overview of the Aug 2, 2022 release of Karbon's Public API.

### `GET Organization by OrganizationKey`

In addition to `BusinessCards` property, we have also added a new property - `Contacts` - to the `$expand` option in `GET` by `OrganizationKey` endpoint. Using the new property, you can receive a list of Contacts associated with the Organization specified using the `OrganizationKey`.

**Example use case**

You want to retrieve a list of contacts associated with an Organization. To receive these Contacts, use `GET` method on the URL as:

`https://api.karbonhq.com/v3/Organizations/{OrganizationKey}?$expand=Contacts`

You might also want to retrieve a list of both contacts and business cards associated with an Organization. To receive Contacts and BusinessCards at the same time, use `GET` method on the URL as:

`https://api.karbonhq.com/v3/Organizations/{OrganizationKey}?$expand=Contacts,BusinessCards`
