# Using Boto3 with VAST Cluster S3

> [!NOTE]
> Note
> 
> Comprehensive documentation for Boto3 can be found on [Boto 3's official documentation site](https://boto3.amazonaws.com/v1/documentation/api/latest/index.html). Please use the official Boto3 documentation as needed in conjunction with our specific guidelines for using Boto 3 with VAST Cluster.

Boto3 is an SDK for python that enables you to interact with AWS services through python code, including the S3 service. Boto3 offers two ways to interface with the S3 APIs:

- [Client](/docs-5-3/docs/boto3-client): provides a low-level service access. There is a method available to the client that maps directly to each of the supported S3 APIs.Boto3 Client
- [Resource](/docs-5-3/docs/en/using-the-boto3-s3-service-resource): provides a higher level object-oriented access to the service.Using the Boto3 S3 Service Resource

You can use either interface to access the S3 APIs that VAST Cluster supports.

In both cases, when you create the client or resource, it creates a default session which manages configuration and state. The session can and will look for configurations in various places including several configuration files. However, configuration files do not allow you to specify an endpoint URL, so we will show you how to pass all configuration parameters, including the S3 endpoint, S3 user credentials, and other settings, in the client or resource creation call.

###### Install the SDK

Start by installing the Boto3 SDK for python:

```plaintext
$ pip install boto3
```
