**Built-in** means that it doesn't need any configuration (in most cases) and there's an instruction on how to use it inside the card.

**Not connected** means that you haven't enabled this service/tool. Once you enable it, the badge will change to **Connected**.

Some integrations are available both on **Free** and **Pro Plans**, and some of them are Pro only.
