Evolution API is a collection of system components including a WhatsApp API gateway, a multi-channel messaging bridge, and a conversational AI orchestrator. It functions as an event-driven messaging middleware that links messaging platforms with large language models and external applications to automate text and audio responses.
The project provides a self-hosted marketing automation platform for executing customer relationship workflows and outreach campaigns. It further distinguishes itself by routing chat conversations between different messaging services and customer support tools through a unified interface.
The system covers omnichannel messaging management, real-time event streaming to external queues, and the automation of business communications. It also includes capabilities for syncing conversations with bot builders and offloading binary media to cloud object storage.
