Beyond the built-in Colossal app, Colossal connects to many third-party services — payment providers, marketing platforms, notification tools, and more. Each connection you add brings its own **events** (which can start an automation) and **actions** (which an automation can run), available in the [Automation Builder](/automations/overview) right alongside Colossal's built-in events and actions. Add connections from the [Colossal dashboard](https://app.colossal.sh). For the full catalog — and the events and actions each connection provides — see [colossal.sh/apps](https://colossal.sh/apps). See every available connection and the events and actions it provides.
