Action NodesAction nodes are the building blocks of Actionflows |
and are represented as a circle with an icon. They perform specific tasks, e.g. |
decision gateways, performing calculations, and API integrations, and are |
joined together using connectors.

Action nodes can be dragged from the toolbar onto the canvas to create a new action, and some can be clicked to see existing objects, e.g. click
to list existing screens, which can then drag be dragged from the Repository onto the canvas.Insert excerpt _action_screen _action_screen nopanel true
Most action nodes run once per record they receive on their driving from the input connection point. However, some action nodes only trigger once run after receiving the final record or once per flow, e.g.

Usually, action nodes have 
Driving connections, which pass data through to the next action node. Some action nodes have a 
Lookup connection, which send out a request for data, that is then returned to the action node data.
Nodes must be connected sequentially starting from the 
Driving interface connection point. Records will then pass through each node and be manipulated accordingly.
For most action nodes, data flow is configured when attributes are mapped to the input connection points. For Insert excerpt

Where attributes require processing by an action node, e.g. in an expression, the attributes must be mapped in as Input Parameters. These attributes are then mapped out of the action node as Output Attributes. Connectors between the action nodes pass through every attribute*, including any not mapped**. *attributes not mapped are referred to as pass-through attributes. **there can be exceptions, e.g. Converge action.
