“WhatsApp messaging for the business whose app2email API key you hold: send approved templates, reply within the 24 hour window, read conversations, hand a conversation to a person, manage contacts and the Do Not Call list. Send ONE DataPart per message: {"skill": "<skill id>", ...arguments} (any tool of the app2email MCP server is a skill; the argument names are the MCP tool's). Text-only messages are answered with input-required. Tasks complete at once and are kept in memory for a while (not across restarts): read the result from the SendMessage answer.
