I’ve tried just downloading the mediacard plugin and inserting the spotify ID and secret number in the blueprints.yaml file but it does not work.
Simply paste the embed code into your markdown content:
### Spotify Embed Test
<iframe src="https://embed.spotify.com/?uri=spotify:user:spotify:playlist:3rgsDhGHZxZ9sB9DQWQfuf" width="300" height="380" frameborder="0" allowtransparency="true"></iframe>
Done.
It works! Thank you for your quick answer!
