# Streaming Catalog Updates Through Collect Tracking Code

To configure server-side streaming updates for items in your catalog, use the API key or catalog import option. Streaming updates replaces the standard file upload process.

![Important](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-mktg-mc_data_management_and_analytics-264-0-0-production-enus/7988f60d-cd94-4b42-8836-dc11773564b5/images/icon_important.png)

Important Streaming updates using client-side JavaScript isn’t supported.

To remove an item from the pool of recommendable items, use the API.

- Requests to the server-side streaming updates service via HTTP aren’t accepted. Instead, use HTTPS in all requests to the streaming update service.
- API keys sent as URI query parameters aren’t accepted. Instead, move the API key into the body of the request.

In this example, replace `MID` with the account ID of the business unit used for Collect Tracking Code.

```json
{
  "api_key": "a1234567-cccc-1234-a123-12345a123456",
  "payload": {
    "item": "INSERT_ITEM",
    "unique_id": "INSERT_UNIQUE_ITEM_ID",
    "item_type": "INSERT_ITEM_TYPE",
    "name": "INSERT_ITEM_NAME_OR_TITLE",
    "url" : "INSERT_ITEM_URL",
    "INSERT_ATTRIBUTE_NAME": "INSERT_ATTRIBUTE_VALUE"
  }
}
```
