# Connecting to the Boto3 Client Interface

To connect to the low-level client interface, use Boto3’s [client()](https://boto3.amazonaws.com/v1/documentation/api/latest/reference/core/session.html#boto3.session.Session.client) method. You must pass your VAST Cluster S3 credentials and other configurations as parameters with hardcoded values. This is the only way to specify a VAST Cluster VIP as the S3 endpoint.

The following example imports the boto module and instantiates a client with the minimum configuration needed for connecting the client to your VAST Cluster S3 account over an HTTP connection:

```plaintext
import boto3
s3_client = boto3.client(
    's3',
     use_ssl=False,
     endpoint_url=<ENDPOINT-URL>    
     aws_access_key_id=<ACCESS-KEY>,
     aws_secret_access_key=<SECRET-KEY>
     region_name=<REGION>
     config=boto3.session.Config(
          signature_version='s3v4'
          s3={'addressing_style': 'path'}
    
     )
)
```

in which:

- `&lt;ENDPOINT-URL&gt;` can be any of the cluster's Virtual IPs, prefixed by *http://*. For example, `http://198.51.100.255`, in which *198.51.100.255* is one of the cluster's VIPs.

> [!NOTE]
> Note
> 
> To retrieve the cluster's virtual lPs:
> 
> - In the VAST Web UI, from the left navigation menu choose Network Access -> Virtual IPs to open the Virtual IPs page. It shows you which virtual IPs are configured on each CNode.
> - In the VAST CLI, run the `vip list` command.
- `&lt;ACCESS-KEY&gt;` and `&lt;SECRET-KEY&gt;` are your [S3 key pair](/docs-5-3/docs/en/managing-s3-user-access-from-the-vast-web-ui-tg).
- `&lt;REGION&gt;` can be any string. It is required if `signature_version=S3v4`.

###### For HTTPS Connection

For an HTTPS connection, pass parameters as follows in the [client()](https://boto3.amazonaws.com/v1/documentation/api/latest/reference/core/session.html#boto3.session.Session.client) call:

- Enable HTTPS by setting `use_ssl=True` instead of `use_ssl=False` .
- If the default certificate trust store does not recognize the signer of the installed certificate, you can use the `verify` parameter to specify a non default path to the certificate trust store. If you're using a self signed certificate, you can point this to the certificate itself. For example:

```plaintext
verify="path/to/client/cert.pem"
```
- Alternatively, you can use the `verify` parameter to disable verification:

```plaintext
verify=False
```
