How to Connect Amazon S3 to CloudPairs

Before you start

Requirements

An AWS IAM access key with permissions for the bucket or prefixes you need.

The AWS region for the bucket, such as us-east-1.

A bucket name if you want CloudPairs to open a specific bucket by default.

Setup

In CloudPairs, select Add Cloud Drive or open Connections and choose Add connection.

Select Amazon S3 from the provider list. The same form also supports custom endpoints through the optional Endpoint field.

Add a connection name, region, Access Key ID, Secret Access Key, and optional default bucket.

Click Test connection. CloudPairs verifies the credentials and bucket listing before you save.

Save the connection, open it in either pane, and copy files to local storage, R2, SFTP, or another S3 bucket.

Best practices

Create keys with only the S3 actions and bucket prefixes required for your workflow.

For non-AWS S3 APIs, use the S3-compatible guide so endpoint and region behavior are clear.

Troubleshooting

AccessDenied

Check IAM policy permissions for ListBucket, GetObject, PutObject, DeleteObject, and the bucket ARN/prefix.

Wrong region error

Confirm the bucket region in AWS and update the Region field in CloudPairs.
