Messaging infrastructureHTTP API
Reactions, typing, and formatting
Use Wisent extensions for tapbacks, typing indicators, expressive effects, and decorated text where the backend supports them.
Reactions, typing, and formatting — contract and behavior
- POST /v3/chats/{chat_id}/reactions adds or removes supported iMessage tapbacks against a target message.
- Typing and rich-text support depend on the chosen backend; AppleScript-only mac-relay cannot drive every private Messages feature.
- The private-API helper exposes selected IMCore capabilities through a structured loopback protocol.
- Feature absence is reported as a backend capability result rather than silently degrading formatted content.
