Twilio IP Messaging is a suite of APIs that allow developers to embed advanced person-to-person chat in mobile apps, SaaS products, and websites. With IP Messaging, developers can maintain context that's critical to the conversation, providing a better user experience by linking conversations to the situation in which they arise. This allows for richer interactions and experiences, such as real-time communication features and contextual messaging. Twilio provides a reliable cloud infrastructure, including pub/sub systems and storage solutions, to handle high traffic loads and ensure message delivery reliability and security. The IP Messaging SDK is part of Twilio's RTC SDKs, providing modular access to communications functionality for advanced chat features.
