# SendMsg integration

> What this integration supports through the Unified.to API, by object. Live data: `GET https://api.unified.to/unified/integration?type=sendmsg` with your workspace API key (or Core MCP `list_unified_integrations` with `type: "sendmsg"`). All integrations: https://docs.unified.to/integrations.md

## Overview
