The Start, End (success), and End (failure) nodes have a single connector to which you connect the nodes in your workflow. The Start node connects to the first node in your workflow; the End (success) and End (failure) nodes can connect to any number of nodes.
These three nodes are always present in the workflow and cannot be deleted. The Start and End (success) nodes must be connected. The End (failure) node can be left unconnected. All failure (red) connectors that are not explicitly connected within the workflow are implicitly connected to the End (failure) node.
The left side of each node also displays a single input connector to which you connect other nodes in the workflow.
- An email node to send email in a failure scenario
- The next node in the workflow
- The End (success) or End (failure) nodes in the workflow
