Catenis Flow Guide

List Exported Assets Node

The List Exported Assets node retrieves a list of previously exported Catenis Smart Assets that satisfy your search criteria. Then the node returns the status of these assets as well as further relevant information.

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 directions on setting up a new virtual device that you can find here.

Catenis Flow Setting Fields

  1. Asset ID: Enter the ID of a previously migrated and exported Catenis Smart Asset.
  2. Foreign Blockchain: Select a foreign blockchain that the asset has been exported to among the available foreign blockchains, which currently include: Ethereum, Binance Smart Chain, and Polygon PoS Chain.
  3. Token Symbol: This is the ticker symbol for the foreign token (e.g., BTC).
  4. Status: Enter a single status or a comma-separated list of statuses, such as pending, success, error, etc. Your search will be filtered to include these statuses.
  5. Negate Status: Enter a single status or a comma-separated list of statuses, such as pending, success, error, etc. Your search will be filtered to exclude these statuses.
  6. Start Date: Specify the start date of the period you wish to see the history.
  7. End Date: Specify the end date of the period you wish to view the history.
  8. Limit: Specify the maximum number of issuances returned. (Optional)
  9. Skip: Specify the number of issuances to skip. (Optional)

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 List Assets Node from the Catenis Flow pallet area 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.  Please refer to the description of each field under the section named “Node Properties Panel Field Description” for 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 “List Exported Assets” 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 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.

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 set 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


{
    "selector": {
        "assetId": " Insert_Your_Asset_ID_Here ",
        "foreignBlockchain": "ethereum",
        "tokenSymbol": "EDT",
        "status": "pending,success,error",
        "negateStatus": false
    },
    "limit": 3
}

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.
