Understanding the List Permission Events Node

In this quick tutorial, we will cover Understanding the List Permission Events Node. In this tutorial, you will learn about the List Permission Events Node and how it’s used in Catenis Flow.

In this video we will cover:

• What information this node retrieves
• Importing an example 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 Permission Events Node in Catenis Flow

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

Hi, this is Claire for Blockchain of Things.

In this tutorial, you will learn about the List Permission Events Node and how it’s used in Catenis Flow.

The List Permission Events Node retrieves a list of system-defined Permission Events.

The events are specific actions that can be taken

based on what permission is set, and at what permission level.

Name the node using the name field and set a Catenis Virtual Device in the connection field.

Now, let’s take a look at the example flow found at this link:

Copy the example flow.

Click the Node-RED hamburger menu, and click import to display the import flow dialog box.

Paste the flow into the import box and click the import button.

This flow is a working example implementing the List Permission Events Node.

Note, that after importing the example flow,

you will need to set the Catenis Flow Nodes to your own previously configured virtual device.

You can pause this tutorial now, to explore this flow on your own.

In the next video, you’ll learn how to create this flow yourself.

Great!

Now you should understand List Permission Events Nodes.

In our next tutorial, you’ll learn how to use the List Permission Events Node.
