+title: Kevel Destination
+---
+
+With [Kevel](https://kevel.co)'s ad serving APIs, you can build custom ad platforms for sponsored listings, internal promotions, native ads, and more — so you can take back the Internet and drive more revenue.
+
+This destination is maintained by Kevel. For any issues with the destination, [contact the Kevel Support team](mailto:[email protected]).
+
+
+## Getting Started
+
+{% include content/connection-modes.md %} 
+
+1. From the Segment web app, click **Catalog**.
+2. Search for "Kevel" in the Catalog, select it, and choose which of your sources to connect the destination to.
+3. In the [Kevel App](https://app.kevel.co), click the Information icon in the top-right navigation to find your **Network ID**.
+4. Still in the [Kevel app](https://app.kevel.co), go to **Settings -> API Keys** in the top navigation. Either copy an existing key, or generate a new one.
+5. Back in the Kevel destination settings in the Segment app, enter the values for the **Network ID** and the **API Key**.
+
+
+## Identify
+
+If you aren't familiar with the Segment Spec, take a look at the [Identify method documentation](https://segment.com/docs/connections/spec/identify/) to learn about what it does. An example call would look like:
+
+```js
+analytics.identify('userId123', {
+  email: '[email protected]'
+});
+```
+
+Segment sends Identify calls to Kevel as [UserDB updates](https://dev.kevel.co/docs/userdb-1). Traits with `boolean` values are stored as `interests` on the UserDB Record. Other traits are stored in the `custom` property.
