The Event API allows you to send event data to Optimizely's logging servers from all of your applications, whether they're web, mobile, or server-side implementations. Once we have your data, we use it to calculate your campaign and experiment metrics and display them on Results page. The event data is also available in raw format via the Data Export service.
We "consume" our own API: the Optimizely X clients and SDKs send event data with this API. This consistency helps ensure that your data is processed the same way, regardless of how we receive it.
