# Downloader

The `youtube_download` source delivers the audio/video content of a YouTube video of your choice. Please note that due to the potentially large data volume this source is only available via the asynchronous [**Push-Pull integration**](https://developers.oxylabs.io/scraping-solutions/web-scraper-api/integration-methods/push-pull) and the [**Cloud Storage**](https://developers.oxylabs.io/scraping-solutions/web-scraper-api/features/result-processing-and-storage/cloud-storage) feature.

## How YouTube Downloader works

1. Submit via API:
   * One or more YouTube video IDs;
   * Cloud storage details.
2. Get the API response with the confirmation that your request to download a video has been successfully accepted.
3. Get the videos in the specified cloud storage location as soon as they're processed by our system.

{% hint style="success" %}
**Note**:

* The downloader defaults to 720p video resolution. If 720p is not available, the downloader will pick the best available quality below 720p. You can override this behaviour by using the `context: video_quality`parameter.
* You can download videos of up to 12 hours in length.
* The download time is limited to 1 hour.

The API will respond with a JSON object, containing the job information for each job created. The job status will be **`pending`** until the download is completed.

## Checking job status

If you provided a valid [**callback URL**](https://developers.oxylabs.io/scraping-solutions/integration-methods/push-pull#callback) when submitting your job, we will notify you upon completion by sending a `JSON` payload to the specified callback URL.&#x20;

However, if you submitted a job without using [**callback service**](https://developers.oxylabs.io/scraping-solutions/integration-methods/push-pull#callback), you can check the job status manually. Retrieve the URL from the `href` field in the `rel:self` section of the response message received after job submission. The URL for checking the job status will resemble the following: `http://data.oxylabs.io/v1/queries/12345678900987654321`. Querying this URL will return the job information, including its current `status`.

### Endpoint <a href="#endpoint-1" id="endpoint-1"></a>

```
GET https://data.oxylabs.io/v1/queries/{id}
```

## Cloud storage

You can get your YouTube videos delivered to [**Google Cloud Storage**](https://developers.oxylabs.io/scraping-solutions/features/result-processing-and-storage/cloud-storage#google-cloud-storage), [**Amazon S3**](https://developers.oxylabs.io/scraping-solutions/features/result-processing-and-storage/cloud-storage#amazon-s3), [**Alibaba OSS**](https://developers.oxylabs.io/scraping-solutions/features/result-processing-and-storage/cloud-storage#alibaba-cloud-object-storage-service-oss), or [**other S3-compatible cloud storage**](https://developers.oxylabs.io/scraping-solutions/features/result-processing-and-storage/cloud-storage#other-s3-compatible-storage).

Content files will appear in your cloud storage location and will be named according to one of the following naming schemas:

* `{video_id}_{job_id}.mp4` – for video
* `{video_id}_{job_id}.m4a` – for audio

### **Google Cloud Storage setup** <a href="#google-cloud-storage-setup" id="google-cloud-storage-setup"></a>

To get your job results uploaded to your Google Cloud Storage bucket, please **set up special permissions for our service** as shown in our [Google Cloud Storage documentation](https://developers.oxylabs.io/scraping-solutions/features/result-processing-and-storage/cloud-storage#google-cloud-storage).

```json
{
    "source": "youtube_download",
    "query": "9cQBNYsCqQs",
    "storage_type": "gcs",
    "storage_url": "bucket_name/path"
}
```

### Amazon S3 setup

To get your job results uploaded to your Amazon S3 bucket, please set up access permissions for our service. To do that, go to [**https://s3.console.aws.amazon.com/**](https://s3.console.aws.amazon.com/) → **`S3`** → **`Storage`** → **`Bucket Name`**` ``(if you don't have one, create a new one)` → **`Permissions`** → **`Bucket Policy`**.

Use the bucket policy below (don't forget to change the bucket name under `YOUR_BUCKET_NAME`):

```json
{
    "Version": "2012-10-17",
    "Id": "Policy1577442634787",
    "Statement": [
        {
            "Sid": "Stmt1577442633719",
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::324311890426:user/oxylabs.s3.uploader"
            },
            "Action": "s3:GetBucketLocation",
            "Resource": "arn:aws:s3:::YOUR_BUCKET_NAME"
        },
        {
            "Sid": "Stmt1577442633719",
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::324311890426:user/oxylabs.s3.uploader"
            },
            "Action": [
                "s3:PutObject",
                "s3:PutObjectAcl"
            ],
            "Resource": "arn:aws:s3:::YOUR_BUCKET_NAME/*"
        }
    ]
}
```

This policy allows us to write to your bucket, give access to uploaded files to you, and know the location of the bucket.

### Alibaba Cloud OSS setup

In order to save results to your Alibaba Cloud Object Storage Service (OSS), you must create the `ACCESS_KEY_ID` and `ACCESS_KEY_SECRET` and use them to form the storage URL. Follow the instructions outlined in our [Alibaba Cloud OSS documentation ](https://developers.oxylabs.io/scraping-solutions/features/result-processing-and-storage/cloud-storage#alibaba-cloud-object-storage-service-oss).

```json
{
    "source": "youtube_download",
    "query": "9cQBNYsCqQs",
    "storage_type": "s3_compatible",
    "storage_url": "https://ACCESS_KEY_ID:ACCESS_KEY_SECRET@BUCKET_NAME.oss-REGION.aliyuncs.com/FOLDER_NAME"
}
```

### S3-compatible storage setup

If you'd like to get your results delivered to other S3-compatible storage location, you'll have to include your bucket's `ACCESS_KEY:SECRET` auth string in the `storage_url` value in the payload:

```json
{
    "source": "youtube_download",
    "query": "9cQBNYsCqQs",
    "storage_type": "s3_compatible",
    "storage_url": "https://ACCESS_KEY:SECRET@s3.oxylabs.io/my-videos"
}
```
