Working with the List Permission Events Node

In this quick tutorial, we will cover Working with the List Permission Events Node. In this tutorial, we’ll create a flow containing the List Permission Events Node.

This node can only be used 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.

In this video we will cover:

• How this node works
• What the action button is and how it’s used in Catenis Flow
• Deploying and testing your flow

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 List Permission Events Node in Catenis Flow

After watching Working with the List Permission Events Node, feel free to watch the next video, Understanding the Retrieve Permission Rights Node, to further expand your knowledge.

Hi, this is Claire for Blockchain of Things.

In this tutorial, we’ll create a flow containing the List Permission Events Node.

If you don’t know what a List Permission Events Node is,

make sure you check out the previous video,

titled “Understanding the List Permission Events Node”.

Let’s get started!

This node can only be used in Interactive Mode,

which allows the end user to click on the action button attached to the left of the node.

This action triggers the Catenis API method, passing the parameters set in the nodes properties slide-out panel.

Drag a List Permission Events Node into your workspace.

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

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

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

Now, click the deploy button.

To test the flow, click the square gray box attached to this node on the left.

A JSON object containing all possible Permission Events should now be printed to the Debug Sidebar.

Great work!

Now that you know how to create a flow using the List Permission Events Node,

it’s time to move on to our next tutorial,

where you’ll learn all about the Retrieve Permission Rights Node.
