This is my first twitter card I’m trying create. Im trying to create an app card buffer sometime I’ve been getting the same message telling me not whitelisted, need some help been reading but no one has posted a solution for this.
Please give us more details about your card and the website where you are trying to use a card. Usually you get this error when submitting an invalid card to the validator.
yes the website is 60secondworkoutchallenge.com
its a website for my app and would like to promote through twitter i have very limited knowledge on this as i recently knew about this from researching online
Check this topic which has more details about the “not whitelisted” error, and what to do next.
There is no Twitter Cards markup on your page, so that’s the first problem.
ok thank you
