Amazon S3 Connected System

Manage AWS S3 data stores with Appian! Users can access their S3 objects directly from an Appian interface. Appian documents can be uploaded to a S3 bucket with Server-Side Encryption and be configured as Public or Private.
The AWS S3 Connected System Plug-in uses the AWS Java SDK to connect to S3.

The following operations are included:

  • Create Bucket -- Adds a new bucket to the S3 instance. A bucket is needed in order to store objects(files)
  • Upload File -- Uploads a file to any specified bucket on the S3 instance
  • Upload Multiple Files -- Uploads multiple files to any specified bucket on the S3 instance
  • List Buckets -- Returns all available buckets on the S3 instance
  • List Objects -- Returns all available objects from a specified bucket
  • Delete Bucket -- Permanently removes a bucket from the S3 instance
  • Delete Object -- Permanently removes an object from a specified bucket
  • Download Object -- Downloads object from specified bucket and saves to Appian Folder


  • 19.3 is now required to use this Connected System with Download Document functionality. If you have a 19.1 or 19.2 version of Appian, then please request the previous version of this Connected System from Appian Support.
  • Access Key Id: the access key id for connecting to S3 can be retrieved from AWS Management Console Navigate to the Users > Summary page and click the “Security credentials” tab
  • Secret Access Key: the secret access key can only be viewed once upon the creation of an access key, see AWS Access Keys documentation for more information:
  • Note: Users that want to upload objects as 'Public' must have the correct IAM privileges or an "Access Denied" error will return. The s3:ListAllMyBuckets Action is needed to establish a Test Connection. Additionally, your IAM User will need the respective Action for each operation (i.e Upload File -> PutObject, Download Object -> GetObject) in their IAM Policy.
