Twitter Cards: 'WARN: Not whitelisted'



I’m trying to implement Twitter Cards on the site and the Card Validator brings up the message ‘WARN: Not whitelisted’. Is it possible to have the site whitelisted?



Once you add Twitter Cards markup to your pages, you can submit them to the validator and they will be automatically whitelisted if the markup is valid. The only card type that requires approval is the Player Card.


Great, ok thanks Andy.

Additionally is there any way to flag up to the relevant team at Twitter about getting our account verified? Our organisation (The Music Producers Guild) has members including Paul Epworth (Adele, Florence and the Machine, U2), Jake Gosling (Ed Sheeran, One Direction), Brian Eno (Coldplay, U2) and many others.

There’s nothing we can do to around Verification here as these are developer forums. Information on Verified accounts is available on our Help site.
