Getting Started

This integration creates a workflow with a HTTP / Webhook trigger and Helper Functions action. When you configure and deploy the workflow, it will run on Pipedream's servers 24x7 for free.

  1. Select this integration
  2. Configure the New Requests (Payload Only) trigger
    1. Connect your HTTP / Webhook account
  3. Configure the Download File To /tmp action
    1. Connect your Helper Functions account
    2. Configure Download File URL
    3. Configure Target Filename
  4. Deploy the workflow
  5. Send a test event to validate your setup
  6. 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.

Trigger

Description:Get a URL and emit the HTTP body as an event on every request
Version:0.1.1
Key:http-new-requests-payload-only

Trigger Code

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

// Core HTTP component
// Returns a 200 OK response, emits the HTTP payload as an event
export default {
  key: "http-new-requests-payload-only",
  name: "New Requests (Payload Only)",
  // eslint-disable-next-line
  description: "Get a URL and emit the HTTP body as an event on every request",
  version: "0.1.1",
  type: "source",
  props: {
    // eslint-disable-next-line
    httpInterface: {
      type: "$.interface.http",
      customResponse: true,
    },
    http,
  },
  async run(event) {
    const { body } = event;
    this.httpInterface.respond({
      status: 200,
      body,
    });
    // Emit the HTTP payload
    this.$emit({
      body,
    });
  },
};

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.
LabelPropTypeDescription
N/AhttpInterface$.interface.httpThis component uses $.interface.http to generate a unique URL when the component is first instantiated. Each request to the URL will trigger the run() method of the component.
HTTP / WebhookhttpappThis component uses the HTTP / Webhook app.

Trigger Authentication

The HTTP / Webhook API does not require authentication.

Action

Description:Downloads a file to [your workflow's /tmp directory](https://pipedream.com/docs/code/nodejs/working-with-files/#the-tmp-directory)
Version:0.3.0
Key:helper_functions-download-file-to-tmp

Helper Functions Overview

Pipedream provides a set of helper functions that make it easy to manipulate
and work with data in your workflow. You can use these helper functions to:

  • Perform mathematical operations on data
  • Format data
  • Extract data from arrays and objects
  • Convert data from one format to another
  • Manipulate dates and times
  • Generate random data

Here are some examples of what you can build using the Helper Functions API:

  • A calculator that performs mathematical operations on data
  • A formatter that formats data
  • An extractor that extracts data from arrays and objects
  • A converter that converts data from one format to another
  • A date and time manipulator
  • A random data generator

Action Code

import helper_functions from "../../helper_functions.app.mjs";
import { axios } from "@pipedream/platform";
import fs from "fs";

export default {
  key: "helper_functions-download-file-to-tmp",
  name: "Download File To /tmp",
  description: "Downloads a file to [your workflow's /tmp directory](https://pipedream.com/docs/code/nodejs/working-with-files/#the-tmp-directory)",
  version: "0.3.0",
  type: "action",
  props: {
    helper_functions,
    url: {
      type: "string",
      label: "Download File URL",
      description: "Enter the URL of the file to download",
    },
    filename: {
      type: "string",
      label: "Target Filename",
      description: "The filename that will be used to save in /tmp",
    },
  },
  async run({ $ }) {
    const {
      url, filename,
    } = this;

    const resp = await axios($, {
      url,
      responseType: "arraybuffer",
    });

    /**
     * Saves file to /tmp folder and exports file's file name and file path,
     */
    const rawcontent = resp.toString("base64");
    const buffer = Buffer.from(rawcontent, "base64");
    const downloadedFilepath = `/tmp/${filename}`;
    fs.writeFileSync(downloadedFilepath, buffer);

    const filedata = [
      filename,
      downloadedFilepath,
    ];

    return filedata;
  },
};
