What Yup Chat RCS API is

Yup Chat RCS API creates one or more RCS agents in a single request. It accepts conversational and non-conversational agents for transactional, promotional, and OTP uses. Profiles can define names, descriptions, interaction details, colors, logos, banners, preview images, phone numbers, email addresses, websites, privacy policies, and terms. The create-agent endpoint accepts JSON authenticated with an x-api-key header, while brand-owner details support approval or authorization. RCS messages can include images, videos, GIFs, carousels, and buttons for replies, links, calls, and locations. Businesses can show a verified sender name and logo, view delivery, read, and interaction analytics, and use SMS fallback for unsupported devices. Communications are encrypted in transit. APIs connect with CRM, ERP, and automation systems. Listed devices include Android 5.0+ with Google Messages and iPhones running iOS 18.1+. A web form also supports agent setup.
