# Connect to object storage

> Learn how to connect to your object storage buckets.

You can connect to your object storage using an S3-compatible API, an SDK, or the AWS CLI. Below are some examples of commands you can use with these methods. For a full list of compatible commands, refer to [S3 API compatibility](https://developers.cloudflare.com/r2/api/s3/api/).

If you currently have a bucket with AWS or GCP and would like to transfer your files from this bucket to Sevalla, please [contact our Support Team](/support/contact-support/).

## AWS CLI

### Configure your bucket

```
aws configure set aws_access_key_id YOUR_ACCESS_KEY
aws configure set aws_secret_access_key YOUR_SECRET_KEY
aws configure set default.s3.signature_version s3v4
aws configure set default.s3.endpoint_url YOUR_ENDPOINT_URL
```

### Generate a pre-signed URL

```
aws s3 presign s3://YOUR_BUCKET_NAME/FILENAME --expires-in 3600 --endpoint-url YOUR_ENDPOINT_URL
```

### Upload a file

```
aws s3 cp LOCAL_FILENAME s3://YOUR_BUCKET_NAME/ --endpoint-url YOUR_ENDPOINT_URL
```

### Download a file

```
aws s3 cp s3://YOUR_BUCKET_NAME/REMOTE_FILENAME DOWNLOADED_FILENAME --endpoint-url YOUR_ENDPOINT_URL
```

### List your bucket objects

```
aws s3 ls s3://YOUR_BUCKET_NAME/ --endpoint-url YOUR_ENDPOINT_URL
```

## Boto3 (Python SDK)

Install Boto3 if you haven’t already:

```
pip3 install boto3
```

Enter Python interactive mode:

```
python3
```

### Connect to your object storage

```
import boto3
from botocore.client import Config

# Set up R2 connection
s3 = boto3.client(
    "s3",
    endpoint_url="YOUR_ENDPOINT_URL",
    aws_access_key_id="YOUR_ACCESS_KEY",
    aws_secret_access_key="YOUR_SECRET_KEY",
    config=Config(signature_version="s3v4"),
)
```

### Generate a pre-signed URL

```
presigned_url = s3.generate_presigned_url(
    "get_object",
    Params={"Bucket": "YOUR_BUCKET_NAME", "Key": "REMOTE_FILE_NAME"},  # Replace values
    ExpiresIn=3600,  # Expiration time in seconds (e.g., 1 hour)
)

print("Pre-signed URL:", presigned_url)  # Ensure this prints
```

### Upload a file

```
s3.upload_file("LOCAL_FILENAME", "YOUR_BUCKET_NAME", "UPLOADED_FILENAME")
```

### Download a file

```
s3.download_file("YOUR_BUCKET_NAME", "REMOTE_FILENAME", "DOWNLOADED_FILENAME")

```

### List your bucket objects

```
response = s3.list_objects_v2(Bucket="your-bucket-name")
print(response)  # See what files exist
```
