Getting Started#

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

Select this integration
Configure the New Requests (Payload Only) trigger
1. Connect your HTTP / Webhook account
Configure the Generate PDF from HTML String action
1. Connect your Browserless account
2. Configure HTML String
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 Requests (Payload Only) on HTTP / Webhook

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

HTTP / Webhook Overview#

Build, test, and send HTTP requests without code using your Pipedream workflows. The HTTP / Webhook action is a tool to build HTTP requests with a Postman-like graphical interface.

Point and click HTTP requests

Define the target URL, HTTP verb, headers, query parameters, and payload body without writing custom code.

$A screenshot of Pipedream's HTTP Request Configuration interface with a GET request type selected. The request URL is set to 'https://api.openai.com/v1/models'. The 'Auth' tab is highlighted, indicating that authentication is required for this request. In the headers section, there are two headers configured: 'User-Agent' is set to 'pipedream/1', and 'Authorization' is set to 'Bearer {{openai_api_key}}', showing how the OpenAI account's API key is dynamically inserted into the headers to handle authentication automatically.$

Here's an example workflow that uses the HTTP / Webhook action to send an authenticated API request to OpenAI.

Focus on integrating, not authenticating

This action can also use your connected accounts with third-party APIs. Selecting an integrated app will automatically update the request’s headers to authenticate with the app properly, and even inject your token dynamically.

Pipedream integrates with thousands of APIs, but if you can’t find a Pipedream integration simply use Environment Variables in your request headers to authenticate with.

Compatible with no code actions or Node.js and Python

The HTTP/Webhook action exports HTTP response data for use in subsequent workflow steps, enabling easy data transformation, further API calls, database storage, and more.

Response data is available for both coded (Node.js, Python) and no-code steps within your workflow.

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.

Label	Prop	Type	Description
N/A	`httpInterface`	`$.interface.http`	This component uses `$.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 / Webhook	`http`	`app`	This component uses the HTTP / Webhook app.

Trigger Authentication#

The HTTP / Webhook API does not require authentication.

Browserless Overview#

The Browserless API on Pipedream allows you to automate browser actions without the overhead of managing your own browser infrastructure. This service provides a way to run Chrome browser sessions programmatically, making it ideal for web scraping, automated testing, and screenshot capture. Leveraging this on Pipedream, you can create serverless workflows that interact with web pages, extract data, and perform actions as a human would, all in a scalable and efficient manner.

Action Code#

// legacy_hash_id: a_B0ip1E
import { axios } from "@pipedream/platform";

export default {
  key: "browserless-convert-html-to-pdf",
  name: "Generate PDF from HTML String",

  version: "0.4.1",
  type: "action",
  props: {
    browserless: {
      type: "app",
      app: "browserless",
    },
    html: {
      type: "string",
      label: "HTML String",
      description: "HTML to render as a PDF",
    },
  },
  async run({ $ }) {
    const { html } = this;

    const data = await axios($, {
      method: "POST",
      url: `https://chrome.browserless.io/pdf?token=${this.browserless.$auth.api_key}`,
      headers: {
        "Cache-Control": "no-cache",
        "Content-Type": "application/json",
      },
      responseType: "arraybuffer",
      data: {
        html,
        options: {
          displayHeaderFooter: true,
          printBackground: false,
          format: "Letter",
        },
      },
    });

    $.export("pdf", Buffer.from(data, "binary").toString("base64"));
  },
};

Action Configuration#

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

Label	Prop	Type	Description
Browserless	`browserless`	`app`	This component uses the Browserless app.
HTML String	`html`	`string`	HTML to render as a PDF

Action Authentication#

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

Sign-up for a browserless account, it will create a unique token that allows service interaction.

About Browserless#

Browserless is a service that allows you to run headless Chrome instances in the cloud.
