Catenis Flow Guide

Asset Export Outcome Node

The Asset Export Outcome node allows you to retrieve the current information about a previously exported Catenis Smart Asset into the foreign blockchain. It displays the status of the export, its outcome progress, and the success or failure of each exported asset. This node will also display the smart contract address deployed on the foreign blockchain.

Node-RED Specific Fields

  1. Name Field:  Add a descriptive name that will help differentiate this node from others of the same type on the Node-RED workspace (not required).
  2. Connection Field: This drop-down selection is required.  Set a previously configured Catenis connection (virtual device). If you need to configure a new virtual device, click the pencil button to the right of the field and follow the direction on setting up a new virtual device that can be found here:

Catenis Flow Setting Fields

  1. Asset ID: Enter the ID of an asset that has previously been exported to a foreign blockchain.
  1. Foreign Blockchains – On this drop-down field, select the foreign blockchain that the Catenis Smart Asset has been exported to. The blockchains currently available to export to are, Ethereum Binance Smart ChainPolygon PoS Chain

Note: This node can be used in two modes: “Interactive” and “Run-Time.”

How to Use in Run-Time Mode

  1. Drag-and-drop the Asset Export Outcome Node from the Catenis Flow pallet on the left-hand side of the interface to the Node-RED workspace. Double-click on the node to display the properties slide-out panel.
  2. On the “Device” drop-down field of the properties slide-out panel, choose the Catenis Virtual Device you previously configured. The virtual device is a configuration node containing the Catenis Virtual Device information (The device ID and API Secret key). If you do not have a virtual device already configured, please refer to our documentation titled: “Configure your First Virtual Device on Node-RED” here:
  3. Add the node’s configuration information to each field of the properties slide-out panel based on your needs.  Please refer to the description of each field under the section named “Node Properties Panel Field Description” on proper usage.
  4. Then, wire this node to a debug node. 
  5. Next, drag-and-drop an “inject” node to the Node-RED workspace.
  6. Wire the “inject” node to the “Asset Export Outcome” node, and double click the inject node to open its properties slide-out panel. 
  7. Alter the information in the inject node’s properties slide-out panel by selecting the drop-down “Payload” field and choosing the “JSON” Type. An Ellipse button “…” will appear to the right of the field. Click this ellipse button to display a JSON edit box. 
  8. Enter the JSON information you wish to pass as an input to the Catenis Node (an example JSON input is below). After entering your JSON text entry, click the red “Done” button. Click the Done button again to exit the properties dialogue box.
  9. Click the red “Deploy” button on the upper right-hand side of the Node-RED dashboard to deploy this flow.
  10. Now, let’s test the flow: Click the button on the left attached to the inject node to send the input from the inject node to the flow.
  11. The debug sidebar should display the returned JSON object containing the API call results to the right side of the workspace.
  12. After running the Asset Export, a smart contract is created on the foreign blockchain. If you need the address of the smart contract to add to your wallet, you can find it in the JSON result in the id property.

How to Use Interactively

  1. In Interactive Mode: The end-user clicks on the action button (on the left) attached to the node. Then the Catenis API method is called, using the default settings (as specified in the node’s properties slide-out panel configuration).
  2. Follow steps 1 through 4 under “How to use in Run-Time Mode” in the section above.
  3. Click the red “Deploy” button on the upper right-hand side of the Node-RED dashboard to deploy this flow.
  4. Now, let’s test the flow: Click the button on the left attached to this node to send the default property panel setting to the Catenis APIs and through the flow. 
  5. The debug sidebar should display the returned JSON object containing the results to the right side of the workspace

Example JSON Object that can be passed to the Catenis Flow Node


{
    "assetId": "Insert_Your_Asset_ID_Here",
    "foreignBlockchain": "ethereum"
}

Note: Inputs injected into this node via a JSON object containing alternate node properties will override the properties set on this node's slide-out properties panel.
