Creator in Twitter Card


Is it possible to display the creator or some other link to my profile in a summary_large_image ?
I added both
<meta name="twitter:creator" content="@robin_linus">
<meta name="twitter:creator:id" content="4675481071">
but nothing changes.


Can I bump this question up? Reading the documentation at, adding the twitter:creator tags should show the @ username of the author of the content, but nothing is showing up. similarly with the twitter:site tag. We’ve just added this in, but don’t see anything displayed in the validator or indeed the cards when displayed on Twitter. Do we need to be whitelisted for these to show up?
