Getting Started#

This integration creates a workflow with a Open Exchange Rates trigger and Node action. When you configure and deploy the workflow, it will run on Pipedream's servers 24x7 for free.

Select this integration
Configure the New Currency Fluctuation trigger
1. Connect your Open Exchange Rates account
2. Configure Polling interval
3. Select a Currency Id
4. Configure Change
Configure the Run Node Code action
1. Connect your Node account
Deploy the workflow
Send a test event to validate your setup
Turn on the trigger

Details#

This integration uses pre-built, source-available components from Pipedream's GitHub repo. These components are developed by Pipedream and the community, and verified and maintained by Pipedream.

To contribute an update to an existing component or create a new component, create a PR on GitHub. If you're new to Pipedream component development, you can start with quickstarts for trigger span and action development, and then review the component API reference.

New Currency Fluctuation on Open Exchange Rates

Description:Emit new event when a new significant change in a specified currency rate is detected.

Open Exchange Rates Overview#

The Open Exchange Rates API provides real-time and historical exchange rates for currencies worldwide, which enables you to retrieve the latest currency data for any purpose like financial reporting, pricing products in multiple currencies, or converting currency for international transactions. In Pipedream, you can tap into this API to create workflows that automate currency-related tasks, enrich data with current exchange rates, and trigger actions based on currency fluctuations.

Trigger Configuration#

This component may be configured based on the props defined in the component code. Pipedream automatically prompts for input values in the UI and CLI.

Label	Prop	Type	Description
Open Exchange Rates	`app`	`app`	This component uses the Open Exchange Rates app.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.
Polling interval	`timer`	`$.interface.timer`	Pipedream will poll the Open Exchange Rates on this schedule
Currency Id	`symbol`	`string`	Select a value from the drop down menu.
Change	`change`	`string`	The change you consider significant.

Trigger Authentication#

Open Exchange Rates uses API keys for authentication. When you connect your Open Exchange Rates account, Pipedream securely stores the keys so you can easily authenticate to Open Exchange Rates APIs in both code and no-code steps.

Getting started

First, open an account on the Open Exchange Rate dashboard.

Then confirm your email address with the link sent to your account's email address.

Then, copy and paste the App ID into the field below.

Node Overview#

Develop, run and deploy your Node.js code in Pipedream workflows, using it between no-code steps, with connected accounts, or integrate Data Stores and File Stores.

This includes installing NPM packages, within your code without having to manage a package.json file or running npm install.

Below is an example of installing the axios package in a Pipedream Node.js code step. Pipedream imports the axios package, performs the API request, and shares the response with subsequent workflow steps:

Action Code#

import node from "../../node.app.mjs";

export default {
  name: "Run Node Code",
  version: "0.0.2",
  key: "node-run-node-code",
  description: "Write custom Node.js code and use any of the 400k+ npm packages available. Refer to the [Pipedream Node docs](https://pipedream.com/docs/code/nodejs) to learn more.",
  props: {
    node,
  },
  type: "action",
  methods: {},
  async run({
    steps, $,
  }) {
    // Return data to use it in future steps
    return steps.trigger.event;
  },
};
