# Charon — Messenger-to-CRM Integration Gateway > Charon connects WhatsApp, Telegram, WeChat, Matrix, and Max to Bitrix24 using personal accounts; other CRM systems are wired in through its external API and webhooks. Self-hosted deployment keeps all data on the customer's server. Also works without a CRM — includes a built-in team messenger. ## What is Charon Charon is a software gateway for integrating messengers with CRM systems. It connects WhatsApp, Telegram, WeChat, Matrix, and Max to Bitrix24 through employees' personal accounts; other CRMs are wired in through Charon's open REST API and signed webhooks, which your developer wires to your pipelines on the customer side. With Bitrix24, messages from messengers are synced to the CRM automatically: leads, contacts, and conversation history are created for you. Charon also works without a CRM — as a corporate team messenger with a mobile app (Android/iOS). ## Pages - [Home](https://charon24.ru/en/) Main product page: features, how it works, pricing, FAQ, contact form.

WhatsApp Business API is Meta's official channel for mass messaging and template messages. Charon connects a personal or work WhatsApp number through a WhatsApp Web session — the same way WhatsApp Web works in a browser. This is a non-API integration; Meta's official Terms of Service for WhatsApp may impose restrictions, and stability depends on changes in WhatsApp Web. Beyond WhatsApp, Charon supports Telegram, WeChat, and other messengers in a single interface. The two solutions can be used in parallel: Charon for personal customer conversations, WhatsApp Business API for mass campaigns and template messages. ### Can Charon be used without a CRM? Yes. Charon includes a built-in web messenger that works without a CRM. All communication channels are consolidated in a unified chat center. Chats can be assigned to employees and transferred between team members. A mobile app is available. ### Where is conversation data stored? All data is stored in the customer's infrastructure. Charon is a self-hosted solution: conversations, contacts, and media files stay with the customer. AES-256-GCM encryption is used. In a self-hosted deployment the developer (Lemnos LLC) has no access to the customer's data. Cloud deployment in a Russian data center is also available. ### How much does Charon cost? Free tier with 2 connections. Paid plans — up to 2,000 RUB/month per connection; the per-connection price decreases with larger volumes and annual billing (up to 20% off). Registration and demo access are free, no credit card required. ### How to connect WhatsApp to Bitrix24 via Charon? 1. Register at demo.charon24.ru or install Charon on your server. 2.
