Twitter’s new Account Activity API is a useful and powerful way to get tweets delivered right to your web application in real time. How do you use it though?

We’ll talk about:
* OAuth 1 and OAuth 2 with Twitter
* the Account Activity webhooks
* Account Activity subscriptions
* Building an app with Kemal (Sinatra for Crystal)
* Walking through an app that cross-posts from Twitter to Mastodon
* More!

This will be a talk for Rubyists of any skill level; questions and discussion will be encouraged :)
