About this template

A FastAPI application to find YouTube channel ID. By simply providing a video URL, users can retrieve information about the video's channel, including the channel ID and channel name. The app leverages the YouTube API to fetch this data, requiring users to set a YOUTUBE_API_KEY in the environment variables for it to function correctly.

Introduction to the YouTube Channel ID Retrieval Template

This template is designed to help you create an application that can fetch the channel ID and channel name from a given YouTube video URL. It utilizes the YouTube API to extract this information, which can be particularly useful for developers looking to integrate YouTube channel data into their applications or services.

Clicking Start with this Template

To begin using this template, simply click on the "Start with this Template" button. This will pre-populate the code in the Lazy Builder interface, so you won't need to copy, paste, or delete any code.

Initial setup: Adding Environment Secrets

Before you can use this template, you'll need to set up an environment secret for the YouTube API key. Here's how to do it: 1. Obtain a YouTube API key by visiting the [Google Developers Console](https://console.developers.google.com/). 2. Create a project if you haven't already. 3. Navigate to "Credentials" and click on "Create credentials" to generate a new API key. 4. Once you have your API key, go to the Environment Secrets tab within the Lazy Builder. 5. Add a new secret with the key `YOUTUBE_API_KEY` and paste your YouTube API key as the value.

Test: Pressing the Test Button

After setting up your environment secret, press the "Test" button to deploy the app. The Lazy CLI will handle the deployment, and you won't need to worry about installing libraries or setting up your environment.

Entering Input: Filling in User Input

If the template requires user input, you will be prompted to provide it through the Lazy CLI after pressing the "Test" button. For this template, you will need to input the YouTube video URL when prompted.

Using the App

Once the app is deployed, Lazy will provide you with a dedicated server link to use the API. Additionally, since this template uses FastAPI, you will also be provided with a `/docs` link where you can interact with the API's documentation and test endpoints directly. Here's a sample request you might make to the API:


POST /channel/
Content-Type: application/json

{
    "video_url": "https://www.youtube.com/watch?v=dQw4w9WgXcQ"
}

And here's a sample response you might receive:


{
    "channel_id": "UC38IQsAvIsxxjztdMZQtwHA",
    "channel_name": "RickAstleyVEVO"
}

Integrating the App

If you wish to integrate this app into an external service or frontend, you may need to add the app's server link provided by Lazy to your tool. For example, if you're building a dashboard that displays YouTube channel information, you would send a POST request to the `/channel/` endpoint with the video URL as the payload. Remember to handle the API key securely and not expose it in the frontend or any public repositories. Always use server-side code or environment secrets to store sensitive information like API keys. By following these steps, you should now have a functional application that can retrieve YouTube channel IDs and names based on video URLs, all set up and ready to be integrated into your project.
