Working with the Retrieve Permission Rights Node in Run Time Mode

In this quick tutorial, we will cover Working with the Retrieve Permission Rights Node in Run-Time Mode. In this tutorial, we’ll create a flow containing the Retrieve Permission Rights Node.

In this video we will cover:

• How to alter the information in the properties slide-out panel
• Deploying and testing your flow
• Retrieving the API call results

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 the Retrieve Permission Rights Node
• Basic understanding of the Catenis Permission Levels
• Basic understanding of Permission Events in Catenis Flow

After watching Working with the Retrieve Permission Rights Node in Run-Time Mode, feel free to watch the next video, Working with the Retrieve Permission Rights Node in Interactive Mode, to further expand your knowledge.

Hi, this is Claire for Blockchain of Things.

In this tutorial, we’ll create a flow containing the Retrieve Permission Rights Node.

If you don’t know what a Retrieve Permission Rights Node is,

make sure you check out the previous video,

titled “Understanding the Retrieve Permission Rights Node”.

Let’s begin!

Drag a Retrieve Permission Rights 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.

This should be the device for which you want to receive Permission Event Rights for,

also known as the “Controlling Device”.

Click on the event drop-down menu

and then select the event for which you wish to receive event permissions rights for.

Wire this node, to a Debug Node,

if you wish to see the output of the node printed on the Debug Sidebar.

Otherwise, the output from this node can be passed into another node in the flow.

Next, drag-and-drop an Inject Node into the Node-RED workspace.

Wire the Inject Node to the Retrieve Permission Rights Node,

then double-click the Inject Node to open its properties slide-out panel.

Alter the information in the Inject Nodes properties slide-out panel

by selecting the drop-down payload field and choose the string type.

Enter the Permission Event type in the blank field.

Click deploy.

Now, let’s test the flow!

Click the button on the left of the Inject Node to send

the input from the Inject Node through the flow.

The Debug Sidebar should display the returned JSON object

containing the API call results to the right side of the workspace.

Great work!

After watching this tutorial you should understand how to

use the Retrieve Permission Rights Node in RunTime Mode.

Up next,

you’ll learn how to use the Retrieve Permission Rights Node in Interactive Mode.
