| Input node |
| Nodes process data from left to right. A white square on the left hand side indicates that the node can receive inputs from a message object. The node's documentation will describe the expected input “msg” format. |
|---|---|---|
| Output node |
| A white square on the right hand side indicates that the node can output payload data. If there is more than one icon on the right hand side, it means that the node can output multiple sets of data. |
| Nodes with inputs and outputs |
| If a node has squares on both the left and right, it means it accepts inputs from a message object and can output payload data. For details on the expected inputs and outputs, see each node's on-line documentation (select the node, then review the details in the Info tab). |
| Node with missing configuration |
| A red triangle indicates that all required fields are not properly configured. Double-click the node to find out what field(s) require additional configuration (they will be marked with a red box, like the URL field below), then update the node accordingly. |
| Unsaved node |
| This blue circle indicates that the node is not yet saved in the server. If there is any node with a blue circle icon, the Deploy button will become active. |
