The part parameter specifies a comma-separated list of one or more channelSection resource properties that the API response will include. The part names that you can include in the parameter value are id, snippet, and contentDetails. If the parameter identifies a property that contains child properties, the child properties will be included in the response. For example, in a channelSection resource, the snippet property contains other properties, such as a display title for the channelSection. If you set part=snippet, the API response will also contain all of those nested properties.

This parameter is intended for YouTube content partners that own and manage many different YouTube channels. It allows content owners to authenticate once and get access to all their video and channel data, without having to provide authentication credentials for each individual channel.
