YouTube Connector Requirements
Coveo license for the YouTube connector
Your Coveo license must include support for the YouTube connector to be able to use this connector (see What Information Is Displayed in the License Page?).
A valid Google Account
Using a Google Account, you must log in the Google API Console to authorize Coveo access to YouTube data (see Allowing the Coveo Connector Access to YouTube Data).
The YouTube connector needs an API (YouTube Data API v3) to identity itself to Google. The connector uses this API, which is a link between the connector and the YouTube channels, to access the public videos that you want to index (see Allowing the Coveo Connector Access to YouTube Data).
