## **Retrieving Audiences for a Specific Advertiser**

Audiences created through Criteo's API will be returned for the designated advertiser id.

<EndpointBadge method="get">
  ```http theme={null}
  https://api.criteo.com/legacy/marketing/v1/audiences
  ```
</EndpointBadge>

<CodeGroup>
  ```bash cURL theme={null}
  curl --request GET \
    --url 'https://api.criteo.com/legacy/marketing/v1/audiences?advertiserId=1234' \
    --header 'Accept: application/json'
  ```
</CodeGroup>

 

The API will return an object with an array of all the audiences associated with the advertiser id.

<CodeGroup>
  ```json JSON theme={null}
  {
    "audiences": [
      {
        "id": 9999,
        "advertiserId": 1234,
        "name": "Custom Audience",
