Create a Flow
You can create flows by navigating to the Flows Manager.
See Flows Guides to learn more about leveraging Flows functionality.
Note: You can create a total of 16 Flows Managers.
By default, the flow-1 Flows Manager is created with the status of RUNNING. You can control the status of the flow by clicking Start Flow and Stop Flow. See Manage a Flows Manager to learn more.
If you'd like to organize your flows and store them in multiple Flows Managers, you can follow the steps below and create additional Flows Managers. If you are selecting an existing Flows Manager, proceed to Step 2.
To create a Flows Manager:
- Navigate to Flows Manager. The Overview pane appears.
From the Overview pane, click Add Flow. The Create Flow dialog box appears.

After creating the Flows Manager, you can open the flow canvas to create individual flows.
To create an individual flow:
For the flow manager you want to use, click the Go To Flow Definition icon. The flow canvas opens in a new browser tab.

To connect nodes, hover over a node's gray dot until it changes color, and then drag the connector to another node's gray dot until it changes color.
A node connection
If you are creating a flow for the first time in a Flows Manager, you will need to configure a connection to the connector nodes.
To configure the Connector Nodes:
