# API Integration

API Integration is the best method to optimize EETS, take advantage of all of the greatest features, and automate content updates from your CMS.

The API can be used to perform most functions of the online portal and also serves several unique functions.

Primarily, the API is used to integrate with existing systems, like a CMS, to automate content updates to EETS Keyword Search.

Secondarily, using the API allows you to configure exclusive features, like:

* part taxonomy filters
* custom filters
* part description tags
* category filters
* Smart Box
* part table
* cross-reference
