About This Template

This workflow automatically fetches the Nikkei 225 closing price every weekday and sends a formatted message to a list of users on LINE.

This is perfect for individuals or teams who need to track the market's daily performance without manual data checking.

How It Works

  1. Schedule Trigger: Runs the workflow automatically every weekday at 4 PM JST (Tokyo time), just after the market closes.
  2. Get Data: An HTTP Request node fetches the latest Nikkei 225 data (closing price, change, %) from a data API.
  3. Prepare Payload: A Code node formats this data into a user-friendly message and prepares the JSON payload for the LINE Messaging API, including a list of user IDs.
  4. Send to LINE: An HTTP Request node sends the formatted message to all specified users via the LINE multicast API endpoint.

Who It’s For

  • Anyone who wants to receive daily stock market alerts.
  • Teams that need to share financial data internally.
  • Developers looking for a simple example of an API-to-LINE workflow.

Requirements

  • An n8n account.
  • A LINE Official Account & Messaging API access token.
  • An API endpoint to get Nikkei 225 data. (The one in the template is a temporary example).

Setup Steps

  1. Add LINE Credentials: In the "Send to LINE via HTTP" node, edit the "Authorization" header to include your own LINE Messaging API Bearer Token.
  2. Add User IDs: In the "Prepare LINE API Payload" (Code) node, edit the userIds array to add all the LINE User IDs you want to send messages to.
  3. Update Data API: The URL in the "Get Nikkei 225 Data" node is a temporary example. Replace it with your own persistent API URL (e.g., from a public provider or your own server).

Customization Options

  • Change Schedule: Edit the "Every Weekday at 4 PM JST" node to run at a different time. (Note: 4 PM JST is 07:00 UTC, which is what the Cron 0 7 * * 1-5 means).
  • Change Message Format: Edit the message variable inside the "Prepare LINE API Payload" (Code) node to change the text of the LINE message.

Automatically Send Daily Nikkei 225 Closing Price to LINE

This n8n workflow automates the process of fetching the daily closing price of the Nikkei 225 index and preparing it for distribution. While the provided JSON only includes the data fetching and preparation steps, the workflow is designed to simplify the regular delivery of this financial data.

What it does

  1. Triggers on a Schedule: The workflow starts automatically at predefined intervals.
  2. Fetches Nikkei 225 Data: It makes an HTTP request to an external API to retrieve the latest Nikkei 225 closing price.
  3. Processes Data: A Code node is used to process the raw data received from the API, likely extracting the relevant closing price and potentially formatting it.
  4. Edits Fields: The "Edit Fields (Set)" node transforms or renames data fields, ensuring the data is in the desired structure for subsequent actions (e.g., sending to LINE).

Prerequisites/Requirements

  • n8n Instance: A running instance of n8n.
  • External API for Nikkei 225 Data: An API endpoint that provides the Nikkei 225 closing price. This workflow assumes such an API exists and is configured within the HTTP Request node.
  • LINE Account (Implied): While not explicitly in the JSON, the workflow's name suggests an integration with LINE for sending messages. A LINE account and a LINE Notify token or similar setup would be required for the final delivery step (which is not included in this JSON).

Setup/Usage

  1. Import the Workflow: Import the provided JSON into your n8n instance.
  2. Configure HTTP Request:
    • Open the "HTTP Request" node.
    • Ensure the URL and any necessary authentication headers or query parameters for your Nikkei 225 data API are correctly configured.
  3. Review Code Node:
    • Open the "Code" node.
    • Verify the JavaScript code correctly parses the response from your chosen Nikkei 225 API and extracts the closing price. Adjust as necessary based on your API's response structure.
  4. Configure Edit Fields (Set) Node:
    • Open the "Edit Fields (Set)" node.
    • Adjust the field transformations to match the desired output structure for your LINE message.
  5. Schedule the Trigger:
    • Open the "Schedule Trigger" node.
    • Set the desired interval for the workflow to run (e.g., daily at a specific time after market close).
  6. Add LINE Integration (Not in JSON): To complete the workflow as suggested by its name, you would need to add a LINE node (e.g., LINE Notify) after the "Edit Fields (Set)" node. Configure this node with your LINE credentials and a message template using the processed Nikkei 225 data.
  7. Activate the Workflow: Save and activate the workflow.

If AI returns non-JSON, keep “Return only a JSON array” as the last line of the prompt and keep jsonOutput enabled. Consider adding validation on parsing.warnings to gate Salesforce writes. For discounts/taxes in OLI: Standard OLI fields don’t support per-line discount amounts directly; model them in UnitPrice or custom fields. Replace the Composite API URL with your org’s domain or use the Salesforce node’s Bulk Upsert for simplicity.
