# Salesforce Knowledge UI API

Retrieve and update data and metadata of Salesforce Knowledge records with the UI API to help build your Lightning Experience UI for your mobile or custom web app.

**note:** UI API isn’t supported for Classic Knowledge.

To learn how to use the UI API, go to the [User Interface API Developer Guide](https://developer.salesforce.com/docs/atlas.en-us.uiapi.meta/uiapi/).

You can find supported Knowledge objects and how to use them in the [Supported Objects](https://developer.salesforce.com/docs/atlas.en-us.uiapi.meta/uiapi/ui_api_get_started_supported_objects.htm) section of the UI API Developer Guide.
