Twilio has added support for RCS (Rich Communications Services), next-generation carrier messaging, enabling developers to build more engaging, rich messaging experiences while leveraging the reach of SMS. With this support, developers can use one API to deliver rich messages on any device, reaching every user. Twilio is also introducing Rich Messaging Extensions, which extend the Programmable SMS API with additional optional parameters for including rich content and interactive experiences. This allows businesses to send branded messages, share rich cards, and include carousels for scrolling through products, while enabling read receipts and click-through data. RCS support enables businesses to reach consumers with more engaging content, transforming consumer expectations for all messaging experiences. With Twilio's support, developers can now build applications that support both SMS and RCS, without custom code for every different channel.
