You need to create an API key and each request will cost a certain amount of Request-Points (depending on the kind of query).

It may help to understand youtube's domain model before starting.

It's best to just try out your requests in the browser to see what you will get.
A request can look like this (note that you have to replace the playlist ID and the API key in order to make this request work):

https://www.googleapis.com/youtube/v3/playlistItems?playlistId=<PLAYLIST_ID>&key=<API-KEY>A&part=snippet&fields=nextPageToken,items(snippet(publishedAt,resourceId(videoId)))
