Video tags being removed from Admin API

I am trying to add some content to my ghost installation via the admin api. The content of the HTML parameter displays correctly as the content of the post, but when I add the native video tags they are removed prior to the post being added.
This is an example of the video tag that is being removed.

<video controls>
     <source src="some url...">
</video>

I’m guessing this is some type of security measure? Any suggestions on how to prevent the video tags from being removed?

Try wrapping it with card hints:

<!--kg-card-begin: html-->
<video controls>
     <source src="some url...">
</video>
<!--kg-card-end: html-->

This worked! Thanks for the quick response.
