The documentation clearly states that you need to call the twitter card metatags in the header. While I know this is not well-formed, is there any problem in including it outside of the head?
The issue is that we are trying to distribute player embeds to a video we serve to a number of 3rd party sites. We want them to include the twitter card markup, but we can’t explicitly control whether the 3rd party sites will put the metatags in the head.
Thanks!
