Hi, i’m just curious. We use a third party application to post on Twitter- Social Sign In. I want to use Twitter cards on our website, but wonder if they’ll work as we’re not technically posting through Twitter. Has anyone else tried it? I know I should just test it out, but we’re re-designing our site, aiming to add the code to our new website. But in the mean time I thought i’d put it out there! Thanks
Cards are not visible in third-party client apps, but they should work for Tweets posted from third-party clients.
