Torii provides a public API where you can fetch and modify data displayed in the platform. The API Access section lists your organization's stored keys, their expiration dates, who created them and when.  On-hover, each entry will display a trashcan icon for removal.

Torii maintains a developer platform located at https://developers.toriihq.com/ with guides for creating custom workflow actions and connecting custom integrations.
