I'm trying to use "app deep links" so that tweets open an app to specific content. I have followed all the tutorials about setting up the app to recognize URL schemes, and added an App Card to the website. The card validator seems to say everything is good, and that the website is whitelisted.
If I include a link to the website, I do see the App card show up and a prompt to install the app. (yay!)
But I can't find any information now on how to use the custom url schemes. How do I post a tweet that includes a link that uses the URL scheme? I tried just adding my custom URL to a tweet, but it doesn't get treated as a URL and on the mobile device it doesn't open up the app.
PS -- my first time on the forums. Sorry if I've used the wrong form, or template.
