This refers to the entire sequence of processing. | | **Step** | An individual unit of processing that makes up a Flow | Each individual process like receiving email, AI summarization, Slack notification. | | **Tool** | A component that performs a specific action | AI models, API integrations, file processing | | **Secrets** | Securely stored sensitive values | API keys, OAuth tokens | | **Workspace** | A space to organize your Flows, Secrets, and team resources | Project workspace | The diagram below shows how these concepts relate to each other: * A single **Workspace** can be shared by multiple **Accounts**, and one Account can belong to several Workspaces. * Each Workspace contains one or more **Flows**, and every Flow is composed of ordered **Steps**. * Each Step implements its functionality through exactly one **Tool**. * **Secrets** live at the Workspace level, but the same Secret can be reused across multiple Flows and Steps inside that Workspace. * Secrets are how Steps reach **External Services** (APIs, OAuth integrations) without exposing credentials in flow definitions.
