Chat SDK has added a Telegram adapter, enabling bot development across Slack, Discord, GitHub, Teams, and now Telegram from a single codebase.
- •The adapter supports mentions, message reactions, direct messages, and typing indicators.
- •Developers can render basic text cards with buttons and link buttons displayed as inline keyboard elements.
- •Single file uploads are supported through the adapter.
- •Message history relies on adapter-level caching since Telegram does not expose full historical message APIs to bots.
- •Limitations include 64-byte callback data cap and no support for modals or ephemeral messages.
