Evolution API began as a WhatsApp controller API based on CodeChat, which in turn implemented the Baileys library. While originally focused on WhatsApp, Evolution API has grown into a comprehensive platform supporting multiple messaging services and integrations. We continue to acknowledge CodeChat for laying the groundwork.
Today, Evolution API is not limited to WhatsApp. It integrates with various platforms such as Typebot, Chatwoot, Dify, and OpenAI, offering a broad array of functionalities beyond messaging. Evolution API supports both the Baileys-based WhatsApp API and the official WhatsApp Business API, with upcoming support for Instagram and Messenger.
For those who need a more streamlined and performance-optimized version, check out Evolution API Lite. It's designed specifically for microservices, focusing solely on connectivity without integrations or audio conversion features. Ideal for environments that prioritize simplicity and efficiency.
Evolution API supports multiple types of connections to WhatsApp, enabling flexible and powerful integration options:
-
WhatsApp API - Baileys:
- A free API based on WhatsApp Web, leveraging the Baileys library.
- This connection type allows control over WhatsApp Web functionalities through a RESTful API, suitable for multi-service chats, service bots, and other WhatsApp-integrated systems.
- Note: This method relies on the web version of WhatsApp and may have limitations compared to official APIs.
-
WhatsApp Cloud API:
- The official API provided by Meta (formerly Facebook).
- This connection type offers a robust and reliable solution designed for businesses needing higher volumes of messaging and better integration support.
- The Cloud API supports features such as end-to-end encryption, advanced analytics, and more comprehensive customer service tools.
- To use this API, you must comply with Meta's policies and potentially pay for usage based on message volume and other factors.
Evolution API supports various integrations to enhance its functionality. Below is a list of available integrations and their uses:

To continuously improve our services, we have implemented telemetry that collects data on the routes used, the most accessed routes, and the version of the API in use. We would like to assure you that no sensitive or personal data is collected during this process. The telemetry helps us identify improvements and provide a better experience for users.
