WARN: Not whitelisted


I run a few Twitter pages for my company and am trying to get the summary cards to work. I noticed that Twitter Cards no longer requires whitelisted approval, but for some reason, when I run our links through the Validator, it’s unable to render a preview and the log states the site is not whitelisted.

Here’s an example of a page from one of our websites. http://www.cliniciansbrief.com/article/top-5-clinical-situations-can-t-wait

Can you advise?


There’s no twitter:card tag in your page, so there’s no card to render or whitelist.


I am trying to validate the following page http://yovivo.it/eeE3QQ== but am repeatedly getting this error even when I change teh metadata completeley.

Anything I have missed?


I don’t see any twitter:card tags in your page at all?


The site is a single page javascript application and so we are redirecting bots to a JSP page. The meta data on this page is as follows:

The page is generated on the server and we have a bot redirect in place.

This is the metadata we are using:

<meta name="twitter:card" content="summary_large_image" />
   <meta name="twitter:site" content="@yovivoapp" />
   <meta name="twitter:title" content="some title" />
   <meta name="twitter:description" content="some content" />
   <meta name="twitter:image:src" content="https://apis.yovivo.it:443/someimage.png" />
   <meta name="twitter:image:width" content="480" />
   <meta name="twitter:image:height" content="480" />
