description: "Summary of the configurable components Corridor exposes for customizing dashboards, data-lake access, approvals, exports, and external integrations."
---

Corridor offers various configurable components which makes it very flexible.
The users can create their own set of dashboards, read from and save to any type of data-lake, add shortcuts
to the platform for external apps, export the artifacts to external apps, get approval from external reviewers.
The user could also create custom APIs, using the `corridor` package and use those APIs from external applications.
