Merge Node

The Merge node lets you unify multiple inputs into a single output within Spaceflow.

It is used when two or more flow paths need to converge before continuing to the next node. The Merge receives the outputs from nodes connected to its inputs and consolidates that information into a single output.

The Merge node requires at least 2 inputs to function.

How it works

The Merge node can have multiple inputs (minimum of 2) and a single output.

Each input can be configured individually, allowing you to:

• Define a label for visual identification;
• Determine whether that input will be required for the node's completion.

When the flow reaches the Merge node, behavior depends on the required input configuration.

Merge configuration

The following fields must be filled in the Merge node:

• Node Name (Required) Unique identification of the node within the flow.
• Inputs (Minimum: 2) Define how many inputs the node will have. The system requires at least two inputs to allow the node to be used.
  For each input, you can configure:
  • Label Text displayed on the flow connection line, making visual identification easier.
  • Required Defines whether that input needs to be completed for the node to be considered completed.

You can add new inputs by clicking Add.

Configuration example

Required input behavior

When an input is marked as required, the Merge node will only be completed when all nodes connected to required inputs are completed.

Possible scenarios

• ✅ No required inputs The node can proceed according to the flow logic, without requiring all inputs to be completed.
• ✅ One or more required inputs The node will only be approved when all inputs marked as required are completed.

This lets you control synchronization points in the flow, ensuring that multiple processes finish before continuing.

Input labels

The Label field serves exclusively for visual organization of the flow.

The defined text will be displayed on the line connecting the previous node to the Merge, making it easier to identify the path being unified.

Node output

The Merge node has a single output.

This output contains the consolidated information from all inputs connected to the node.

After the defined conditions are met (mainly the required inputs), the flow will proceed normally to the next node connected to the Merge output.
