Gateway Node

This page is for application designers who need to configure functionality for components or events. It explains the properties for the gateway node, which is part of an actionflow.

Overview

Use a  Gateway node to control the path that data records take as they flow through an actionflow. You can add several output connection points. On the output connection points, you can specify decision logic to control the path of data, record by record.

Example

Sometimes there is a threshold in your data that affects the way you want to process it. For example, you might want someone to approve orders over £1000, whereas orders below this value can be placed without approval.

The application screen, below, lists the orders pending approval.

The actionflow for this requires a gateway node to capture orders with a value of £1000 or more so that it can send these to the person authorised to approve them.
