Reference skill for Zoom Team Chat. Use after routing to a chat workflow when building user-scoped messaging integrations, chatbot experiences, rich cards, buttons, slash commands, or chat webhooks.
npx skills add anthropics/knowledge-work-plugins --skill build-zoom-team-chat-app
Background reference for Zoom Team Chat integrations. Use this after the workflow is clear, especially when the Team Chat API versus Chatbot API distinction matters.
There are two different integration types and they are not interchangeable:
Team Chat API (user type)
authorization_code)/v2/chat/users/...Chatbot API (bot type)
client_credentials)/v2/im/chat/messagesIf you choose the wrong type early, auth/scopes/endpoints all mismatch and implementation fails.
