- **Public or Open API** – Product features exposed for other systems to consume and connect through the API.
- **Webhooks** – Library of events to which other systems can subscribe to be notified programmatically. For example, when an asset is added to the library, a Webhook ensures that another system can subscribe to and monitor that activity.
- **Client Application** – Web application that sits outside Optimizely Content Marketing Platform (CMP) and receives API messages from the CMP API’s and Webhooks.
- **Native Integration** – Optimizely offers many available integrations today through native or out-of-the-box integrations. These include Facebook, YouTube, and LinkedIn, among others. These integrations are maintained by Optimizely and configured in the platform.
- **Custom Integration** – An integration built and maintained by a third party. That third party could be an agency, a partner, or you. The Open API and Feed API help make custom integrations possible.
