How to Build an RCS Business Messaging Campaign with Twilio in PHP

Twilio’s PHP tutorial explains how to create an RCS Business Messaging campaign that delivers branded, interactive messages through recipients’ default messaging apps using the same Programmable Messaging API used for SMS. It covers registering and testing an RCS Sender, attaching it to a Messaging Service, configuring a PHP 8.5 project with Twilio credentials, and creating a reusable rich-card Content Template containing a hero image, personalized text, URL actions, and quick-reply buttons. The campaign script reads recipients from a JSON file, sends personalized template messages through the Messaging Service, and can fall back to SMS for unsupported devices. The tutorial also demonstrates exposing a local PHP webhook server through ngrok to collect message status events including delivery and RCS read receipts, while a separate inbound webhook interprets suggested replies such as promo-code requests and unsubscribe actions using TwiML responses. It concludes with testing instructions, common troubleshooting guidance for sender configuration and webhook issues, and recommendations for production improvements such as database-backed audiences and reporting, carousels, webhook validation, and CRM or customer-data-platform integration.
