Drupal has had the ability to use oEmbed in core since version 8.6.0. It was included along with the other media changes that went into core in that version.
I have used some of the Drupal core oEmbed functionality to include YouTube videos into content, but I've never dug deeper to see what else I could do with it. Although Drupal comes with Vimeo and YouTube services available there are many more services to include, you just need to enable them.
In this article I will show what oEmbed is, how to use it out of the box, and then how to add more services to your system.
