PostBot API 10.3

Bot API 10.3 🔁 Button Revolution • Buttons can now be placed right inside any rich message – with multiple native styles and custom alignment. • Out of the box, these buttons support callbacks, Mini Apps, Login URLs, copying text and more. • Bots can now mark inline buttons as disabled. 👻 Ephemeral Messages • Bots can now replace their messages with an ephemeral overlay, then edit it with rich content or newly uploaded media. This unlocks rich, personalized flows and responses running in a single message. 💪 Rich Messages • Bots can now attach documents to rich messages and more easily embed media – including previously uploaded files. • Rich Messages now support expandable quote blocks and compact tables. 🦀 AI Agents • Bots now support a native Stop button for streamed drafts and can optionally preserve partial responses. • And more, see the full changelog for details: https://core.telegram.org/bots/api-changelog#august-24-2026
