RCS Composer (rcscomposer.com) is a simple tool that allows you to receive an API payload for Google’s RCS endpoints (https://developers.google.com/business-communications/rcs-bu...).

It lets you build messages like rich cards and carousels and then copy the generated JSON to use in your integration.

Bonus: I added a quick reference list of carriers that support RCS on Apple devices.

Would love feedback from anyone building RBM tooling—what’s missing / what’s annoying in current workflows?
