## RCS Fallback Messages

Never lose a message again — RCS messages now **automatically fall back to SMS or MMS** when a recipient's device doesn't support RCS.

### What's new?

**RCS fallback messages**

Include a `fallback` object in your RCS send request with a `from` phone number and `text` or `mediaUrls`. If RCS delivery fails, the message is resent as SMS or MMS automatically.

* **SMS fallback** when only `text` is provided (≤3072 characters)
* **MMS fallback** when `mediaUrls` are included or text exceeds 3072 characters
* Original RCS message status updates to `FALLBACK_SENT`
* Webhook delivers `fallbackMessage` details so you can track both legs
