# RCS Business Messaging — SMS's better-looking sibling.

Rich cards, suggested replies, branded sender, read receipts. Fall back to SMS in one attribute. Same auth, same idempotency, same webhooks as every other Bird channel, because the same engineering team built them all.

## 5 minutes from npm install to first send

## Send a rich message from the language you already use.

SDKs in every major runtime. The first send goes to the sanctioned test number (+15005550006) and falls back to SMS automatically, so the CI check doesn't require an RCS-capable handset.

## Ten primitives between "text" and a real app surface.

RCS is a richer protocol than SMS. We expose the richness as primitives, not as a designer canvas.
