I am doing a small web game application and want my users to share the result picture(can be link) on Twitter. I have read the document a lot and found Twitter card was perfect. But Twitter card doesn’t work for my application Because there is not a proper DNS.
So my question is, Can I do it through Twitter API?
I tried the example in https://dev.twitter.com/rest/public/uploading-media . It worked well but I can only post image on my timeline. Can I use this API to post image on other people’s profile?
