# API Reference Pointers This doc is intentionally lightweight; prefer the official REST reference for the authoritative schema. ## Team Chat API (user-level) - Send message: `POST /v2/chat/users/me/messages` - Typical needs: - list channels - post to channel / DM - thread replies ## Chatbot API (bot-level) - Send bot message: `POST /v2/im/chat/messages` ## Notes - If you see "invalid access token" errors, check: - app type (General App OAuth vs others) - scopes - whether the user re-consented after scope changes
