YouTube API: Upload Videos With Python (Step-by-Step)

Nov 8, 2025 by Admin 54 views

Alright guys, so you want to upload videos to YouTube using Python? Awesome! This guide will walk you through exactly how to do that using the YouTube Data API. It might sound intimidating, but I promise it's totally manageable, even if you're not a coding wizard. We'll break it down into simple steps so you can automate your uploads and save a ton of time. Let's dive in!

Setting Up Your Project and Credentials

First things first, you need to set up a project in the Google Cloud Console and get your API credentials. Think of this as getting your permission slip from Google to access their YouTube services. Here’s how you do it:

Create a Google Cloud Project: Head over to the Google Cloud Console and create a new project. Give it a descriptive name like "YouTube Uploader" so you know what it's for. This project will house all your API configurations.
Enable the YouTube Data API v3: Once your project is created, search for "YouTube Data API v3" in the API Library and enable it. This tells Google that you intend to use the API for YouTube-related tasks.
Create Credentials: Now, you’ll need to create credentials to authenticate your Python script. Go to the "Credentials" page in the Cloud Console. Click on "Create Credentials" and select "OAuth client ID". You might be prompted to configure the consent screen. If so, just fill in the required details (like your application name and support email). For the application type, choose "Desktop app".
Download Your Credentials: After creating the OAuth client ID, you’ll get a JSON file containing your credentials. Download this file and keep it safe! This file is super important because it contains the keys your script will use to authenticate with the YouTube API. I usually rename it to client_secrets.json and keep it in the same directory as my Python script.
Install the Google API Client Library: In your Python environment, you'll need to install the google-api-python-client and google-auth-httplib2 libraries. Open your terminal or command prompt and run: pip install google-api-python-client google-auth-httplib2. These libraries handle the communication between your Python script and the YouTube API.

Setting up these credentials might seem like a lot, but it's crucial for securely accessing the YouTube API. Treat your client_secrets.json file like a password – don't share it with anyone! Once you've got your credentials set up, you're ready to move on to the fun part: writing the Python code.

Writing the Python Script

Okay, now for the code! We'll write a Python script that uses the credentials you just obtained to upload a video to YouTube. Here’s a step-by-step breakdown:

Import Necessary Libraries: Start by importing the required libraries. These libraries will handle the API calls and authentication process:
```
import google_auth_oauthlib.flow
import googleapiclient.discovery
import googleapiclient.errors

scopes = ["https://www.googleapis.com/auth/youtube.upload"]
```
Here, we're importing the google_auth_oauthlib.flow for handling the OAuth 2.0 flow, googleapiclient.discovery for building the YouTube API service, and googleapiclient.errors for handling any API errors. The scopes variable defines the permissions your script needs – in this case, the permission to upload videos to YouTube.

Authenticate and Authorize: Next, you need to authenticate and authorize your script using the credentials you downloaded earlier. This involves creating a flow object, prompting the user to authorize the application, and building the YouTube API service:

def get_authenticated_service():
    flow = google_auth_oauthlib.flow.InstalledAppFlow.from_client_secrets_file(
        "client_secrets.json", scopes
    )
    credentials = flow.run_local_server(port=0)
    return googleapiclient.discovery.build("youtube", "v3", credentials=credentials)

youtube = get_authenticated_service() ```

This code defines a function `get_authenticated_service()` that handles the authentication process. It reads your `client_secrets.json` file, initiates the OAuth 2.0 flow, and prompts you to authorize the application in your web browser. Once authorized, it builds the YouTube API service object, which you'll use to make API calls.

Prepare Video Metadata: Before uploading the video, you need to prepare the metadata, such as the title, description, and category. This metadata helps YouTube understand what your video is about and how to categorize it:
```
request_body = {
    "snippet": {
        "categoryI d": 22,
        "title": "My Awesome Video",
        "description": "This is a description of my awesome video."
    },
    "status": {
        "privacyStatus": "private",
        "selfDeclaredMadeForKids": False,
    }
}

media_file = "path/to/your/video.mp4"
```
Here, request_body is a dictionary containing the video metadata. You can customize the categoryId, title, and description to match your video. The privacyStatus can be set to private, public, or unlisted. The selfDeclaredMadeForKids setting is important for compliance with children's online privacy regulations. Replace `
