Getting Started#

This integration creates a workflow with a YouTube (Data API) trigger and OpenAI (ChatGPT) action. When you configure and deploy the workflow, it will run on Pipedream's servers 24x7 for free.

Select this integration
Configure the New Videos trigger
1. Connect your YouTube (Data API) account
2. Configure Maximum Results
3. Configure Polling interval
Configure the Create Transcription (Whisper) action
1. Connect your OpenAI (ChatGPT) account
2. Select a Audio Upload Type
3. Optional- Select a Language
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.

Trigger#

New Videos on YouTube (Data API)

Description:Emit new event for each new Youtube video the user posts.

Version:0.0.8

Key:youtube_data_api-new-videos

YouTube (Data API) Overview#

The YouTube Data API lets you incorporate functions normally executed on the YouTube website into your own website or application. You can perform operations like searching for videos, retrieving channel data, and managing playlists. When integrated with Pipedream's serverless platform, this API can be part of automations that react to events, synchronize YouTube data with other services, or generate custom reports.

Trigger Code#

import youtubeDataApi from "../../youtube_data_api.app.mjs";
import common from "./common.mjs";

export default {
  ...common,
  type: "source",
  key: "youtube_data_api-new-videos",
  name: "New Videos",
  description: "Emit new event for each new Youtube video the user posts.",
  version: "0.0.8",
  dedupe: "unique",
  props: {
    youtubeDataApi,
    maxResults: {
      propDefinition: [
        youtubeDataApi,
        "maxResults",
      ],
    },
    ...common.props,
  },
};

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
YouTube (Data API)	`youtubeDataApi`	`app`	This component uses the YouTube (Data API) app.
Maximum Results	`maxResults`	`integer`	The maximum number of results in a channel to return. Should be divisible by 5 (ex. 5, 10, 15).
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.
Polling interval	`timer`	`$.interface.timer`	Pipedream will poll the YouTube API on this schedule

Trigger Authentication#

YouTube (Data API) uses OAuth authentication. When you connect your YouTube (Data API) account, Pipedream will open a popup window where you can sign into YouTube (Data API) and grant Pipedream permission to connect to your account. Pipedream securely stores and automatically refreshes the OAuth tokens so you can easily authenticate any YouTube (Data API) API.

Pipedream requests the following authorization scopes when you connect your account:

emailprofilehttps://www.googleapis.com/auth/youtube.readonlyhttps://www.googleapis.com/auth/youtube.uploadhttps://www.googleapis.com/auth/youtubehttps://www.googleapis.com/auth/youtube.force-ssl

About YouTube (Data API)#

With the YouTube Data API, you can add a variety of YouTube features to your application. Use the API to upload videos, manage playlists and subscriptions, update channel settings, and more.

OpenAI (ChatGPT) Overview#

OpenAI provides a suite of powerful AI models through its API, enabling developers to integrate advanced natural language processing and generative capabilities into their applications. Here’s an overview of the services offered by OpenAI's API:

Use Python or Node.js code to make fully authenticated API requests with your OpenAI account:
