Show banners on any surface with the new Banners API

Until now, banners only appeared in the web Messenger, so if you run a native mobile app, a kiosk, or an embedded tool, you had no way to show the same targeted messages there.

The new Banners API lets you fetch the banners a contact matches and display them on any surface you build, using the same audience targeting that already powers your web banners. Dismissals stay in sync across surfaces, so a banner someone dismisses in your app also clears in the Messenger, and the reverse.

Call one endpoint to retrieve a contact's banners and another to record a dismissal, and you control how they render.
