1. Create an account
Go to the main page and click "Sign in to cabinet". You will authenticate through a messenger (Telegram, WhatsApp or MAX). After the first login, your account is created automatically.
Authentication via messengers instead of SMS — no per-message costs. Every authenticated user becomes reachable for notifications by phone number through the same bots. The system picks the right messenger automatically; you control the priority.
Go to the main page and click "Sign in to cabinet". You will authenticate through a messenger (Telegram, WhatsApp or MAX). After the first login, your account is created automatically.
In the cabinet, click "Create application". Fill in the name and, optionally, the description and allowed domains (where the widget runs and where users return after login).
Open the application settings and go to the "General" tab → "Messenger credentials". Add your bot token for Telegram, WhatsApp or MAX. Enable the messengers you need in "Enabled auth methods".
Pick one of three options: Hosted Login (redirect), Widget (embedded button/QR on your site) or direct API calls. See the corresponding tabs for details.
