# YouTube Connector Actions

The supported fetch actions for the YouTube Connector are `Synchronize` and `Identifiers`. These behave similarly but produce different output for the feeds.

A Synchronize Lua script can be used for the `Identifiers` action, but it is often better to use a separate script for the `Identifiers` action, since some of the functions used by a Synchronize script have no meaning for the `Identifiers` action.

The `Synchronize` action uses the script to identify the feeds and feed entries to process and generates documents from each entry to be processed by the ingester.

The `Identifiers` action uses the script to identify the feeds and feed entries to process, but returns minimal properties of the entries within the asynchronous action response. It typically returns a list of IDs or URLs embedded within document identifier strings.
