The Integrations Lab is where you can setup the credentials required to enable certain integrations (e.g. Arena, ShipStation, Shopify, EasyPost).  Before using an integrated Step Type in the Flow Builder you must first enable that integration in the Integrations Lab. From the portal home page, click the Integrations Lab icon to access the Integrations Lab page.

From this page you can select the corresponding tile of the integration you would like to setup which will prompt you for the required information for that integration.  Once setup, the tile will turn green to indicate that the integration is now enabled. 

Once enabled, step types that require this integration in the Flow Builder will turn from grey to white and will become selectable.

Go to the Integrations tab from the BrightReps Resources page for more specific Integration set up instructions and step type examples and uses.
