Spotify is sorted. Now we go to YouTube's side.
The goal of this chapter is simple: get a YouTube API key and find the ID of the YouTube playlist we want to mirror. Two things. That's it.
A Quick Word on the YouTube API
YouTube is owned by Google, so the YouTube API lives inside Google's developer platform. Don't let that intimidate you — you're logging in with the same Google account you use for Gmail or Google Drive. Nothing new to create.
The YouTube Data API has a free tier that gives you 10,000 units per day. Reading a playlist of 100 songs costs about 200 units. So unless you're syncing 50 playlists a day, you'll never hit the limit. We're well within free territory.
