Open platform
Programmable access for bots
Bot APIs live in one open platform, so internal systems, alerts, and AI assistants can plug directly into enterprise conversations.
Common pain point
Disconnected systems and fragmented collaboration
Approvals, alerts, CRM, and AI assistants are scattered across tools, forcing teams to jump between systems and copy-paste information.
Platform solution
A programmable entry into conversations
Use the open platform for bots to connect internal systems, AI, and automation directly into chat.
Compatible
Telegram-like bot experience
Get a token, configure webhooks, receive updates, and call REST APIs with almost no learning curve. Bots can also run via long-polling getUpdates without a public IP.
- REST-style Bot API
- Webhook delivery for updates
- Long-polling getUpdates (v0.10.3)
- Node SDK on npm / Java SDK pending Maven release
Secure
Platform review and token governance
Bot applications are reviewed by platform admins before tokens are issued. Every operation is audited, and tokens are only shown once.
- Admin review console
- Token shown only once / stored as hash
- Revoked tokens stop working immediately
- Audit logs export in one click
Reliable
Reliable async delivery with at-most-once semantics
Message persistence is decoupled from webhook delivery, with retries and signature verification. The same user message is delivered inbound at most once, even in multi-instance deployments.
- Redis Stream async queue
- Exponential backoff and dead-letter queue
- HMAC-SHA256 signature verification
- At-most-once delivery with stable update_id
- Delivery success rate and P95 latency dashboards

Go from zero to your first message in 4 steps
- 1
Submit an application
Fill in the bot name and use case in the developer console, then wait for admin review.
- 2
Get the bot token
Once approved, the token is shown only once and the platform stores only its hash.
- 3
Configure the webhook
Provide an HTTPS endpoint for updates. The platform signs requests and retries while keeping the same update_id for idempotency.
- 4
Call the Bot API
Send messages into enterprise chats, handle callbacks, and drive business workflows.
Review the API docs first to confirm auth and callback flows, then apply for a bot and wire it into your system.
