Working with the List Message Node in Interactive Mode

In this quick tutorial, we will cover “Working with the List Message Node in Interactive Mode”. In interactive mode, the end user clicks on the action button attached to the node, and the Catenis API method is called using the default settings. You are not required to provide any input for nodes that support interactive mode. This video shows how to run the List Message Node interactively.

In this video we will cover:

• Using the List Message Node interactively
• See the interactive results based on the property panel settings

Prerequisite

• A Free Catenis Development account or Production account
• Node-RED installed on either a local or cloud environment
• Catenis Flow Pallet installed on Node-RED
• A Catenis Virtual Device configured on Node-RED
• Basic understanding of how to use Node-RED
• Basic understanding of how messages work in Catenis

Hi, this is Clara for Blockchain of Things.

In this tutorial, we’ll create a flow containing the List Messages Node in Interactive Mode.

In Interactive Mode, the end user clicks on the action button attached to the node,

and the Catenis API method is called, using the default settings.

Before you proceed with this tutorial, you should have already learned how this node works.

As well as how to create a flow using the node in RunTime Mode.

If you haven’t yet completed these tutorials or would like to review, you can access them here:

Ready?

Let’s do this!

Drag-and-drop a List Messages Node
into the Node-RED workspace.

Double-click it to display its properties slide-out panel.

On the device drop-down field, choose your Catenis Virtual Device.

The Virtual Device is a Configuration Node containing the Catenis Virtual Device information.

If you do not have a Virtual Device configured, check out the video at this link:

Add the node’s configuration information based on your needs to each field.

Wire this node to a Debug Node and open the Debug Sidebar.

Click the deploy button.

Now, let’s test the flow.

Click the button on the left of this node to send the default property panel setting to the
Catenis APIs and through the flow.

The Debug Sidebar should display the returned JSON object

containing the results to the right side of the workspace.

Awesome!

Now that you know how to create a flow using the List Messages Node in Interactive Mode,

you can move on to our next tutorial

in which we’ll learn the ins and outs of the Issue Asset Node.
