Livestream API ✅ Streaming on X ✅

@mike_rosinskySep 22
One of my favorite verticals that I've worked on, and there's so much more to come. A world-class streaming platform needs a world-class API to match. Now it's here. Tell your favorite streaming software company to get integrated today.

𝕏 Chat is a full rewrite of DMs on 𝕏 and will replace legacy DMs over time That only works if builders can come along. Businesses ran support & automation on the DM API for years, but none of it works with encrypted messages 𝕏 Chat needed an API of its own. Today it has one

We've completely rebuilt the Android X app from the ground up. It's faster, smoother, and more reliable than the old version in every way. We modernized the foundation so everything just feels better: scrolling, loading, notifications, you name it.
