AWS S3

Manage buckets, files, and folders in Amazon S3

Overview

The AWS S3 tool provides full access to Amazon S3 cloud storage. It supports three resource types: Bucket (create, delete, getAll, search), File (copy, delete, download, getAll, upload), and Folder (create, delete, getAll). File download produces binary data attached to the output item. File upload reads binary data from an upstream item or accepts plain text content. Uses the @aws-sdk/client-s3 package for all S3 operations with automatic SigV4 signing.

Output Data

Results are merged onto the input item’s JSON, so the properties you started with remain available. Binary data on the input item is forwarded, and download adds the file to it.

Resource / Operation	Output
Bucket create, Bucket delete, File delete	One item per input item, carrying success: true.
Bucket getAll	Fans out — one item per bucket, carrying Name and CreationDate.
Bucket search	Fans out — one item per object, carrying Key, LastModified, ETag, Size, StorageClass, plus Owner when Fetch Owner is on.
File copy	One item per input item, carrying LastModified and ETag for the new copy.
File download	One item per input item, carrying fileKey, bucketName, contentType and contentLength, with the file attached as binary.
File getAll	Fans out — one item per object, carrying Key, LastModified, ETag, Size, StorageClass, plus Owner when Fetch Owner is on. Folder markers are filtered out.
File upload	One item per input item, carrying success: true, key and bucket. A binary upload also carries ETag and multipart, which is true when the file was sent as a multipart upload.
Folder create	One item per input item, carrying success: true.
Folder delete	One item per input item, carrying deleted — an array of { "Key": … } for every object removed under the prefix.
Folder getAll	Fans out — one item per folder marker found under the prefix.

When a listing returns nothing, the node still emits one item so the branch does not go silent. That item carries an empty array under a key naming what was listed — buckets, results, files or folders:

{
  "files": []
}

Downloads. The file’s bytes are attached to the output item under the binary property you name in Binary Property (default data), which is what a downstream node such as Knowledge Base or Write to File reads. contentLength and contentType describe the object as S3 reported it.

Uploads. With Binary File on, the node takes the bytes from the named input binary property and, unless you set File Name, reuses that property’s own file name as the S3 key. With Binary File off, it writes the text in File Content to the key in File Name. In both cases Parent Folder Key is prefixed to the key.

Reference results downstream by expression, e.g. {{ $json.Key }} or {{ $json.ETag }}.

Usage Examples

• Download a file from S3 bucket
• Upload a PDF to S3
• List all files in an S3 bucket
• Copy a file between S3 buckets
• Create a new S3 bucket
• Delete an S3 object

Example Configuration

Create a private bucket in a named region:

{
  "type": "aws_s3",
  "parameters": {
    "resource": "bucket",
    "operation": "create",
    "name": "my-workflow-bucket",
    "additionalFields": {
      "acl": "Private",
      "region": "us-east-1"
    }
  }
}

List every bucket the credentials can see:

{
  "type": "aws_s3",
  "parameters": {
    "resource": "bucket",
    "operation": "getAll",
    "returnAll": true
  }
}

Search a bucket recursively under a prefix:

{
  "type": "aws_s3",
  "parameters": {
    "resource": "bucket",
    "operation": "search",
    "bucketName": "my-workflow-bucket",
    "returnAll": false,
    "limit": 200,
    "additionalFields": {
      "prefix": "invoices/2026/",
      "fetchOwner": true
    }
  }
}

Download an object into the data binary property:

{
  "type": "aws_s3",
  "parameters": {
    "resource": "file",
    "operation": "download",
    "bucketName": "my-workflow-bucket",
    "fileKey": "{{ $json.Key }}",
    "binaryPropertyName": "data"
  }
}

Upload a binary file from an upstream node, encrypted and tagged:

{
  "type": "aws_s3",
  "parameters": {
    "resource": "file",
    "operation": "upload",
    "bucketName": "my-workflow-bucket",
    "binaryData": true,
    "binaryPropertyName": "data",
    "fileName": "reports/{{ $json.reportId }}.pdf",
    "additionalFields": {
      "acl": "private",
      "storageClass": "standardIA",
      "serverSideEncryption": "AES256"
    },
    "tagsUi": {
      "tagsValues": [
        { "key": "source", "value": "workflow" },
        { "key": "retention", "value": "90d" }
      ]
    }
  }
}

Upload plain text without any binary input:

{
  "type": "aws_s3",
  "parameters": {
    "resource": "file",
    "operation": "upload",
    "bucketName": "my-workflow-bucket",
    "binaryData": false,
    "fileName": "notes.txt",
    "fileContent": "{{ $json.summary }}",
    "additionalFields": {
      "parentFolderKey": "daily"
    }
  }
}

List the objects at one folder level:

{
  "type": "aws_s3",
  "parameters": {
    "resource": "file",
    "operation": "getAll",
    "bucketName": "my-workflow-bucket",
    "returnAll": true,
    "options": {
      "folderKey": "invoices/"
    }
  }
}

Copy an object between buckets, replacing its metadata:

{
  "type": "aws_s3",
  "parameters": {
    "resource": "file",
    "operation": "copy",
    "sourcePath": "/source-bucket/{{ $json.Key }}",
    "destinationPath": "/archive-bucket/{{ $json.Key }}",
    "additionalFields": {
      "acl": "private",
      "storageClass": "glacier",
      "metadataDirective": "replace"
    }
  }
}

Delete one object, then a whole folder:

{
  "type": "aws_s3",
  "parameters": {
    "resource": "file",
    "operation": "delete",
    "bucketName": "my-workflow-bucket",
    "fileKey": "{{ $json.Key }}"
  }
}

{
  "type": "aws_s3",
  "parameters": {
    "resource": "folder",
    "operation": "delete",
    "bucketName": "my-workflow-bucket",
    "folderKey": "temp/"
  }
}

Create a folder and list the folders under a prefix:

{
  "type": "aws_s3",
  "parameters": {
    "resource": "folder",
    "operation": "create",
    "bucketName": "my-workflow-bucket",
    "folderName": "{{ $json.year }}",
    "additionalFields": {
      "parentFolderKey": "invoices",
      "storageClass": "standard"
    }
  }
}

{
  "type": "aws_s3",
  "parameters": {
    "resource": "folder",
    "operation": "getAll",
    "bucketName": "my-workflow-bucket",
    "returnAll": true,
    "options": {
      "folderKey": "invoices/"
    }
  }
}
